Abstract
This paper reports the results of a survey investigation into the investment decision making
practices of large UK manufacturing companies, especially in relation to investments in
advanced manufacturing technologies. A 24% response rate was received in a survey of the
finance directors of 466 large UK manufacturing companies. Responses were classified into
three groups ranging from non-users of AMT to sophisticated users and analysis revealed that
more sophisticated users do emphasise certain intangible benefits in combination with measures
relating to the traditional dimensions of return and risk.
Key words: Advanced Manufacturing Technology (AMT); capital investment decision; survey;
intangible factors.
1. Introduction
This paper reports the results of a survey investigation into the investment decision making
practices of large UK manufacturing companies. The interest of the researchers was in the
manner in which companies justify investment in advanced manufacturing technologies (AMT)
and whether the methods used are significantly different from those used in justifying non-AMT
investments.
Slagmulder et al. (1995) highlighted strong interest in the topic, perhaps because investment
in Computer-integrated Manufacturing (CIM) technologies such as Computer-aided
Manufacturing (CAM) , Flexible Manufacturing Systems (FMS) and Automated Storage and
Retrieval Systems (AS/RS) can develop manufacturing capabilities that create or sustain
competitive advantage.
The literature can be divided into three strands. First there are a large number of surveys of
practice such as those of Klammer et al (1991) in the USA, Pike and Wolfe (1988) in the UK,
Van Cauwenberg et al. (1996) in Belgium, and Kalyebara (1996) in Australia. These have
concentrated particularly on the measures of financial performance and project risk used in
1
practice. Most survey studies deal with capital budgeting decisions in general and relatively few
with AMT decisions in particular. However, the surveys of Pike et al. (1989) and Slagmulder et
al. (1995) were exceptions and these studies highlighted the importance of non-financial or
‘intangible’ factors in AMT decision making.
A second strand of research can be traced back to Haynes and Solomon (1962), Hastie
(1974) and King (1975). These researchers have gained insights through field studies of practice.
They point out that much of the capital budgeting literature places great emphasis on the
appraisal of investments. However, in practice, investment decisions involve many steps, of
which appraisal is only one, and possibly not the most important. These researchers emphasise
other steps such as the creation of investment proposals, their progress through the organisation,
the interplay of financial and ‘strategic’ information in the process etc. More recent field studies
by Slagmulder and Bruggeman (1992) and Nixon (1995) concentrated on AMT investment
decision making. Their conclusions echo those of the earlier field studies, emphasising all the
stages in the capital budgeting process and the importance of “strategic” (as opposed to purely
financial) considerations in AMT decision making.
A third strand of research can be described as ‘normative’, developing prescriptions for
practice. Whereas the first two strands are broadly descriptive: identifying practice either
through questionnaire surveys or field studies, this strand emphasises the development of
theoretical models. This work has a long history, from the development of the return on
investment (ROI) measure to the discounted cash flow measures of net present value (NPV) and
internal rate of return (IRR). Subsequently, the rapid development of finance theory has seen the
relationship between return and risk theorised and empirically tested (see for example: Lumby,
1995; Davis and Pointon, 1994; and Pike and Dobbins, 1986).
During the 1980s a number of researchers focused on the alleged difficulties of justifying
AMT investment proposals against the, by then traditional, return-risk theoretical framework.
Kaplan and Atkinson (1989) provided a powerful analysis in which they identified excessively
high hurdle rates, incorrect base-case forecasts and failure to recognise all the benefits of AMT
as deficiencies in traditional appraisal methods when applied to AMT investments. Perhaps in
response to Kaplan’s (1986) question: ‘Must AMT be justified by faith alone?’ Several
researchers have developed theoretical models which combine both financial and non-financial
variables and Slagmulder et al. (1995) note: ‘More and more authors are convinced that good
investment appraisal requires that strategic and financial considerations be reconciled and
integrated’.
The increasingly rich literature supplies many possible theoretical models and suggestions as
to how AMT investment decisions ‘should’ be taken. The particular aim of this research was to
test a number of hypotheses and assumptions which are endemic, either implicitly or explicitly,
in the existing literature. These are developed in the next section.
2. Development of Hypotheses
In this section a number of hypotheses will be developed that postulate relationships between
several investment variables (the dependent variables) and level of AMT investment (the
independent variable). Table 1 provides a summary of the dependent variables.
While some authors, (e.g. Primrose and Leonard , 1987 and Park and Son, 1988) suggest that
all the costs and benefits of AMT investments should be quantified financially and others (e.g.
Medearis et al., 1990 and Elango and Meinhart, 1994) suggest that strategic considerations might
totally over-ride financial ones, the majority (e.g. Meredith and Suresh, 1986; Srinivasan and
Millen, 1986; Parsaei and Wilhelm, 1989; O’Brien and Smith, 1993; Accola, 1994; Angelis and
Lee, 1996) opt for a combination of financial and strategic considerations in AMT appraisal.
Meredith and Hill (1987) suggest a relationship between the appropriateness of traditional
financial analysis and strategic analysis in evaluating an investment. They suggest that traditional
2
financial analysis is most appropriate when evaluating stand-alone systems while strategic
analysis becomes most appropriate in evaluating fully integrated systems (see also: Meredith and
Suresh, 1986 and Slagmulder et al., 1995).
These considerations lead to the following two hypotheses:
H1: Companies rely more on strategic decision criteria for AMT investments than for nonAMT investments.
H2: Less reliance is placed on financial analysis for AMT investments than for non-AMT
investments.
Many authors (e.g. Putrus, 1990; Datta et al., 1992; O’Brien and Smith, 1993; and Accola,
1994) have made various assumptions about the ‘intangible’ or ‘strategic’ benefits that are
associated with AMT investments. The ‘normative literature’, especially, is replete with
theoretical analyses that include throughput, market share/growth, flexibility, quality,
organisational learning, company image, human factors, workforce morale, technology position
and other benefits of AMT.
H3: A wide range of intangible benefits become important in the justification of AMT (as
opposed to non-AMT) investment.
The use of capital budgeting techniques such as payback (PB), return on investment (ROI),
and discounted cash flow (DCF) methods has been a major subject in almost every previous
survey. DCF methods have been classified as ‘sophisticated’ while PB and ROI have been seen
as ‘unsophisticated’ or ‘naive’ (e.g. Klammer et al., 1991; Pike, 1988; Chen, 1995). Generally,
surveys have reported increasingly widespread use of sophisticated, DCF, methods with a
preference for internal rate of return (IRR) over net present value (NPV) (Klammer et al., 1991;
Pike, 1988 and 1996). However, the payback period method is still the most widely used
evaluation technique with virtually all companies using it either as a primary or secondary
technique (Lefley, 1994). Previous surveys found a significant relationship between company
size and the use of sophisticated investment appraisal methods such as NPV and IRR with the
largest companies usually using the most sophisticated method(s) (e.g., Schall et al., 1987; Drury
et al., 1993; and Chen, 1995). In the survey reported here, large companies were sampled, so:
H4 : Sophisticated, DCF, methods of investment appraisal are now more important than
unsophisticated methods in large companies.
Just as large companies tend to use more sophisticated techniques it might be expected that
companies investing in more advanced forms of AMT might employ more sophisticated
investment appraisal techniques. Indeed, Woods et al. (1985, p. 42) had expected that ‘… users
(of new technology), by definition, are more advanced in their thinking and therefore more likely
to use more modern investment appraisal techniques with their greater sophistication …’
H5: The sophistication of the financial evaluation technique used increases with the
sophistication of the investment project being evaluated: from non-AMT to fully
integrated AMT.
In addition to ‘financial’ and ‘strategic’ considerations, evaluation of AMT projects, like
other investment opportunities, needs to take account of project risk. Two approaches are usually
considered: the moment-oriented approach and the dimension-oriented approach (see, for
example, Accola et al., 1995; Accola, 1994; Aschenbrenner, 1984; and Schoemaker, 1979). The
moment-oriented approach assumes that data are available to identify the multiple possible
project outcomes and their related probabilities. In this approach, the riskiness of an investment
project may be measured by its standard deviation or variance. The dimension-oriented approach
presumes that project risk can be analysed in different dimensions. For example, Accola (1994)
suggested: impact on company liquidity; variability of project outcomes; and possibility of
massive (ruinous) loss. In recommending a dimension based approach, Accola (1994) argued
that risk adjustment of the hurdle rate or payback period to take account of risk was suspect
3
because this confounded two intrinsically different project characteristics: return and risk. The
following hypothesis is set to test the applicability of Accola’s suggestion:
H6: Practitioners consider three risk ‘dimensions’ to be important: impact of the project on
company liquidity, variability of project outcomes, and possibility of massive loss.
Moment-oriented approaches to risk measurement are usually classified into two categories (Ho
and Pike, 1991; 1992; and Walker and Klammer, 1984). Simple (naive) techniques involve
intuitive adjustments to either the cash flows or a parameter in the evaluation model. For
example, increasing the discount rate, reducing the required payback, or using conservative cash
flow forecasts. Sophisticated techniques, on the other hand, are based on comprehensive
evaluation of uncertainties and include probability analysis, simulation, and the capital asset
pricing model (CAPM). Where researchers (e.g. Meredith and Suresh, 1986 and Hundy and
Hamblin, 1988) have commented on the risk associated with AMT investments, they have
assumed that such investments, because of their large outlays, long lives, delayed benefits and
possibly unfamiliar technology are more risky than other investments.
H7: More sophisticated treatments of risk are employed in the evaluation of AMT as
opposed to non-AMT investments.
Underpinning much of the existing literature is a presumption that traditional, economic/financial
investment appraisal measures systematically penalise AMT investment proposals (see, for
example, Kaplan, 1986; Kaplan and Atkinson, 1989, ch. 12; Dugdale and Jones, 1995; and
Abdel-Kader, 1997). First, traditional, financial, analysis, it is argued, fails to capture many of
the ‘intangible’ benefits which should flow from AMT investment. Second, traditional
approaches militate against AMT because of high discount rates and short payback targets which
systematically penalise long-term investments.
H8: The same financial criteria are applied to AMT investments as other (non-AMT)
investments.
H9: AMT investments are difficult to justify because of failure to recognise all their
“strategic” or “intangible” benefits.
The development of hypotheses is summarised in table 2.
3. Research design and data collection
The survey instrument was designed to identify differences between the evaluation of AMT and
other types of investment and to investigate any relationship between the sophistication of
investments themselves and the sophistication of the technique(s) used to evaluate them. Of
particular interest was the impact of qualitative factors on AMT decisions and how practitioners
incorporate such intangible factors into their analysis. An attempt was therefore made to identify
and investigate all the qualitative factors previously reported in the literature.
Respondents were asked to rate the importance of each technique or criterion on a five-point
rating scale. Previous surveys indicate that most companies use more than one technique, so it
was logical to gather information about the importance of each technique rather than to
categorise or rank them. However, to provide information comparable with previous surveys,
respondents were also asked to identify the financial appraisal technique they regarded as most
important if the firm used several techniques.
While previous studies have compared practices relating to different project types
(replacement, expansion, etc.), no attention has been paid to distinguishing between AMT
investments and other types of investment. A particular feature of this survey is the division of
responding companies into three groups: those not employing AMT; those using less integrated
forms of AMT and those using fully integrated AMT systems. This division facilitated relatively
sophisticated statistical analysis. As noted by Chen (1995), most previous surveys have been
analysed using only simple descriptive statistics but here, Kruskal-Wallis one-way ANOVA was
4
used to compare the importance of various techniques and criteria across each group of
companies. The Kruskal-Wallis one-way ANOVA is a non-parametric statistical test for repeated
measures and three or more mutually independent samples (see, for example, Gibbons, 1993 and
Siegel and Castellan, 1988).
The survey was structured so as to identify the extent of AMT investment in the responding
firm, the techniques employed to measure financial return and risk when evaluating investment
opportunities and the “intangible” variables considered. The grouping of companies according to
their commitment to AMT allowed comparative analysis of the return, risk and intangibles
dimensions. The survey also sought the opinions of practitioners on the expected benefits of
AMT investments and the difficulties they experienced in obtaining approval for AMT
investments.
A postal questionnaire was used to collect primary data. This method was chosen in order to
access a sufficiently large number of respondents without incurring undue costs. The
questionnaire was developed during September 1995 - January 1996 and involved study of the
literature and pilot interviews with finance directors of three UK manufacturing companies in
order to ensure that the final version was not easily misunderstood and of manageable length.
A sample of 466 UK manufacturing companies were chosen from the ‘FAME’ database
(Financial Analysis Made Easy). These companies satisfied two criteria: (1) the first digit of their
primary SIC UK industry codes are either ‘3’ or ‘4’1 so that they operate in the manufacturing
sector, and (2) they are large companies so that they are more likely to have invested in AMT.
The size of companies was measured by three variables: turnover (a minimum of £30 million for
the year ended 1994), fixed assets (a minimum of £30 million for the year ended 1994) and
number of employees (a minimum of 100 employees for the year ended 1994). Based on these
criteria, questionnaires were mailed to the financial directors of 466 large UK manufacturing
companies during the last week of January, 1996 and follow-up telephone calls were made to
non-respondents in the last week of February, 1996. By the end of March 138 responses were
received, a response rate of 29.6%. Of those received, 36 were returned unanswered because the
company policy was not to respond to surveys (20 Companies), the questionnaire was not
relevant to the company (8 companies), lack of time (5 companies), or the company was in the
middle of a merger (3 companies). So, the net response rate was 23.7% (102 completed
questionnaires / 430 potential respondents). Further, three completed questionnaires were judged
as not valid to the analysis because the respondents had not participated in investment evaluation
processes. Hence, 99 usable completed questionnaires were used in the analysis giving a net
usable response rate of 23% (99 / 430). This response rate is comparable with other similar
surveys such as those of Lefley (1994) and of Chen (1995) which had response rates of 28.8%
and 20% respectively.
Follow-up interviews were carried out during April-June 1996 with nine of the respondents
who had experience in AMT decisions making. These interviews enabled the reliability of
questionnaire responses to be checked and allowed further investigation of some issues raised by
the questionnaire results.
In order to assess the possibility of any sample bias the 99 responding companies were
compared with the sample frame of 466 companies. The comparison was based on the two
criteria for choosing the original sample, the industry distribution (according to the first digit of
1
The first digit of ‘3’ includes metal goods, engineering and vehicles industries while the first
digit of ‘4’ includes other manufacturing industries
5
SIC UK primary industry) and the size of the company measured by turnover, fixed assets, and
number of employees for the year ending 1994.
The chi-square test of homogeneity indicated a significant difference between the industry
distribution of the responding companies and the sample frame (p = .005) and a crosstabulation
for the industry distribution of both samples suggested that responding companies might be
biased towards SIC UK industry code ‘3’. Two-sample t-tests were conducted on company size
measured by turnover, fixed assets and number of employees for the year ended 1994. The
results indicated that responding companies were significantly larger than the sample frame in
terms of turnover (p = .007), but not significantly different in terms of fixed assets (p = .943) or
number of employees (p = .981).
To further investigate the effect of non-response bias, the answers to the main questions in
the questionnaire from respondents who replied without the follow-up telephone calls (72
respondents) were compared with the answers from respondents who replied only after the
follow-up telephone calls (27 respondents). There was no significant difference between the two
groups of answers2. Thus, it might be concluded that more respondents would not change the
results of the study.
It can be concluded that non-response bias is not likely to be a threat to the conclusions of the
study. However, the analysis indicates that the findings are more generalisable to larger rather
than smaller companies and to companies with SIC UK primary code ‘3’ rather than ‘4’.
4. Survey Results and Hypotheses testing
4.1. Classification of responding companies
In order to test the research hypotheses, responding companies were categorised according to
their level of AMT investment. Seven types of AMT system are frequently referred to in the
literature: CNC, robotics, AMH, FMS, CAD, CAM and CIM and, following Meredith and
Suresh (1986), these systems were categorised into three groups according to level of integration.
The first level comprised stand-alone systems such as CNC and robotics, the second level
comprised linked systems such as CAD, CAM, and AMH, and the third level comprised
integrated systems such as FMS and CIM.
Seventy-six companies (77%) had invested in AMT and table 3 shows that most of these had
invested in several different AMT applications. The table shows that CAD systems were most
prevalent while the relatively lowest percentages were for FMS and CIM. This categorisation
permitted the operationalisation of the independent variable in the study, defined as ‘degree of
AMT investment’ and ranging from none through stand-alone to fully integrated systems.
There were no companies in the “stand-alone” AMT group, so the companies were classified
into three groups: non-AMT companies, less-integrated companies (those adopting CAD and/or
CAM and/or AMH) and fully-integrated companies which have invested in FMS and/or CIM.
Table 4 summarises the number and percentage in each group.
4.2. The importance of financial return, intangibles and risk in AMT investment
Most of the hypotheses developed postulate differences between the evaluation of non-AMT and
AMT investments. (The exceptions are H4 and H6 that deal with practitioner attitudes to
investment appraisal methods and risk measurement in general). In order to test the hypotheses
responding companies were asked to rate the importance of 27 different factors/techniques in
investment decision making. Responses are summarised in table 5 under four broad headings:
2
For example, means differences in the importance of ‘payback’, ‘quality and reliability of
outputs’ and ‘sensitivity analysis’ were 0.12 (p = .883), 0.10 (p = .834) and 0.20 (p = .318).
6
financial appraisal techniques, non-financial criteria, risk analysis techniques and Accola’s risk
aspects.
In table 5 the mean “score” for each factor/technique is shown separately for each category
of respondents: non-AMT, less integrated and fully integrated. This analysis facilitated the use of
a non-parametric analysis of variance (the Kruskal-Wallis test) in order to determine whether
there were statistically significant differences in the AMT investment behaviour of the three
groups of companies. The results of this test are summarised in table 6.
Table 6 shows that there are no significant differences (at the 5% level) among the three
groups of companies as regards financial appraisal and risk analysis techniques. However, this is
not the case for non-financial criteria. Here there are four criteria: ‘quality and reliability of
outputs’ (p-value = .0006), ‘reduced lead-times’ (p = .0045), ‘obtaining greater manufacturing
flexibility’ (p = .0140), and ‘reduced inventory levels’ (p = .0398) which are significant. It can be
concluded that the importance of these four non-financial criteria are affected by the level of
AMT. All four criteria have higher degrees of importance in fully integrated companies than in
less integrated companies while their importance in less integrated companies is greater than in
non-AMT companies. There is thus evidence that these four ‘strategic’ criteria may be major
reasons for investing in AMT and hypothesis 1, that companies rely more on strategic decision
criteria in evaluating AMT, can be supported3.
The results do not support hypothesis 2: less reliance is placed on financial analysis for AMT
investments than for non-AMT investments. While strategic analysis becomes more important
for AMT companies this is not at the expense of financial analysis. Casual inspection of table 2
suggests that AMT companies see financial analysis as more important than do non-AMT
companies. However, the Kruskal-Wallis test failed to reveal any significant differences in the
behaviour of the three groups of companies and the null hypothesis (no difference between AMT
and non-AMT companies) cannot be rejected.
Analysis of non-financial investment criteria (tables 5 and 6) does suggest that these factors
become more important in AMT investment and significantly so in four cases: quality and
reliability of outputs; greater manufacturing flexibility; reduced lead-times and reduced
inventory levels. Additionally two factors: requirements of customers and consistency with
corporate strategy were seen as important by all respondents with no significant differences
between companies. The remaining factors were not so important, being relatively lowly rated by
all respondents with no significant differences between companies. Hypothesis 3 is supported
but the number of significant intangible benefits is restricted. Four such benefits were identified
in this survey.
Hypothesis 4 relates to investment decision making in general and states: sophisticated, DCF,
methods of investment appraisal are now more important than unsophisticated methods in large
companies. However, on the basis of the sample of large companies surveyed, this hypothesis
cannot be supported. With the exception of discounted payback, all the measures of financial
performance were seen as important, with the unsophisticated methods (payback and ROI) rating
marginally more important than the sophisticated, DCF, methods.
3
Strictly, a hypothesis cannot be ‘proved’, it can only be rejected or supported. Here, the
hypothesis is that there is a difference in reliance on strategic decision criteria across non-AMT,
less integrated and fully integrated AMT companies. The test relates to the null hypothesis- that
there is no difference across companies- and this null hypothesis is rejected. By inference the
alternate hypothesis is supported.
7
The results do not support hypothesis 5: the sophistication of the financial evaluation
technique used increases with the sophistication of the investment project being evaluated. All
the methods of appraisal, with the exception of discounted payback, were considered to be
important and there were no significant differences in the behaviour of the three groups of
companies. The null hypothesis cannot be rejected and it can be concluded that a “package” of
financial return indicators is employed by most companies in appraising investment
opportunities - whether investing in AMT or in more conventional projects.
The results are somewhat inconclusive in testing hypothesis 6: that practitioners consider the
three risk ‘dimensions’: impact on company liquidity, variability of project outcomes, and
possibility of massive loss to be important. Almost as many respondents regarded these issues to
be relatively unimportant as thought them important or very important. Analysis of the results by
type of company was also uninformative with the less- integrated group of companies rating
these issues less important than either the fully integrated or the non-AMT groups of companies.
The results do not support hypothesis 7: that more sophisticated treatments of risk are
employed in the evaluation of AMT investments. Only the relatively unsophisticated technique
of sensitivity analysis was considered to be really important by any of the respondents and the
“AMT companies” were just as reluctant to use sophisticated methods (such as simulation and
the capital asset pricing model) as the non-AMT companies. The Kruskal-Wallis test did not
reveal any significant differences (at 5% level of significance) in the behaviour of the three
groups of companies.
4.3. Further analysis of financial return measures
Respondents who use the payback method as a financial appraisal technique for evaluating
investment projects were asked to indicate the required payback period which is most frequently
used in their firms. Table 7 shows the percentages of respondents for each group of companies.
A period of 3 years or less is most frequently used: 70% of the non-AMT companies, 76% of the
less integrated companies, and 83% of the fully integrated companies require payback in 3 years
or less.
Respondents who use discounting methods were asked to indicate the range of minimum
rates of return or discount rate required by their firms, see table 8. The modal band for non-AMT
companies and less integrated companies was in the range 10 - 15% while it was in the range 16
- 20% for fully integrated companies. The results indicate increasing discount rates from nonAMT companies to less integrated companies to fully integrated companies. In non-AMT
companies 41% of respondents use a discount rate higher than 15% but the corresponding
figures for less integrated and fully integrated companies are 53% and 60% respectively.
The results suggest that the more integrated AMT companies specify more stringent payback
periods and hurdle rates. However, chi-square tests failed to reveal any significant difference in
the behaviour of the three groups of companies and the null hypothesis (no difference between
non-AMT and AMT companies) cannot be rejected.
The survey results appear to support hypothesis 8: the same financial criteria are applied to
AMT as to other investments. (In fact visual inspection of tables 7 and 8 even suggests that
financial criteria may become more stringent from non-AMT to less-integrated to fullyintegrated companies.) The typical payback periods in the range 1 - 3 years and discount hurdle
rates of 10-16% or even more might be expected to penalise AMT investment proposals.
This evidence therefore appears to support these who argue that AMT investment proposals,
with long lives and delayed benefits are penalised by the financial criteria used in their
evaluation. However, caution must be exercised in drawing conclusions about hypothesis 8
because respondents were also asked whether they agreed with the following proposition: “It is
difficult to get AMT investment proposals approved because of stringent financial criteria”. Only
8
15% of respondents agreed or strongly agreed with this statement, the vast majority were either
neutral or disagreed, see table 9.
The conflicting results mean that hypothesis 8 is neither supported nor rejected.
4.4. Further analysis of the benefits of AMT investment
The practices of companies which invest in AMT were further investigated through a question
which aimed to identify which factors they evaluated financially and which non-financially. A
list of 21 benefits was provided and respondents were asked to identify whether each benefit was
considered financially, non-financially or not at all in the evaluation process. The results are
shown in table 10.
These results indicate that eight benefits are almost always considered, either financially or
non-financially, in evaluating AMT investments: reduced material costs (100%), reduced scrap
and rework costs (100%), improved product quality (100%), reduced labour costs (98%),
reduced inventories level (98%), faster response to market needs (97%), improved competitive
position (97%), and reduced lead times (96%). Conversely, a significant minority did not
consider the following four benefits in the evaluation process at all: obtaining experience of new
technology (45%), effects on employee morale (40%), floor space reduction (34%), and reduced
after sale costs (32%).
Most firms were willing to quantify seven benefits in financial terms: reduced labour costs
(97%), reduced material costs (96%), reduced inventories (92%), reduced scrap and rework costs
(89%), increased sales volume (79%), savings from less frequent set-ups (69%), and increased
manufacturing capacity (52%).
The benefits which were considered on a non-financial basis by the majority of respondents
were: improved product quality (86%), faster response to market needs (86%), consistency with
corporate strategy (78%), improved competitive position (77%), greater manufacturing
flexibility (75%), reduced lead times (74%), improved company image (71%), easier production
scheduling (65%), retention of market share (58%), and increased market share (54%)
The results appear to support hypothesis 9: AMT investments are difficult to justify because
of failure to recognise all their strategic or intangible benefits. The responses do indicate that
some benefits might be ignored altogether. However, caution should be exercised in drawing
conclusions, because these benefits (experience of new technology, employee morale, reduced
floor space, reduced after sale costs) are not considered to be particularly important by
practitioners (see table 5).
Two further questions were asked in relation to recognition of the benefits of AMT and the
possibility of implementing AMT investment on “strategic” grounds only (see table 9).
These results again offer broad support for hypothesis 9. Practitioners confirm that some
potential benefits are not taken into account because they are difficult to express in financial
terms and they disagree with the proposition that AMT investment might be approved on nonfinancial grounds alone. Again, however, caution should be exercised in assessing the strength of
these views. If some benefits are unimportant it hardly matters that they are ignored, and, just
because AMT investment cannot normally be justified on non-financial grounds alone, it does
not necessarily follow that AMT is especially difficult to justify.
5. Discussion
The survey indicates that investment projects are affected by three groups of factors: financial
return measures, non-financial criteria, and risk measures. This conclusion is based on the
perceived importance of at least some of the measures or criteria within each group of factors.
For example, the payback period, a financial measure, was judged important or extremely
important by 75% of respondents. Eighty seven percent of respondents considered the ‘quality
and reliability of outputs’, a non-financial criteria, important or extremely important. ‘Sensitivity
9
analysis’, a risk measure, was considered as important or extremely important by 77% of
respondents. The following discussion is structured around these three groups of factors.
5.1. Financial return measures
The evaluation of projected financial return (Hypotheses 2, 4, 5, and 8) remains important. All
the measures of financial return are important, with the ‘naive’ techniques, ROI and payback
period, being seen as marginally more important than the sophisticated discounting techniques.
This finding is consistent across all three groups of companies (non-AMT, less-integrated, and
fully-integrated AMT) so hypothesis 5 that: the sophistication of the project affects the choice of
financial technique, is rejected. This finding is consistent with those of Woods et al (1985),
Lefley (1994) and Chen (1995).
It would be tempting to conclude that investment evaluation is still undertaken in a relatively
naive manner in many companies. However, the continuing importance of payback (see also,
Klammer, 1970; Woods et al., 1985; Schall et al., 1987; Pike, 1982, 1988 and 1996; Drury et al.,
1993; and Lefley, 1994) and ROI should not be taken out of context. The survey results lead to
the rejection of hypothesis 2- that less reliance is placed on economic/financial analysis in
justification of AMT investments than for non-AMT investments. In fact, the results indicate that
all the measures of financial performance are seen as important, whether evaluating AMT or
non-AMT investments. In addition, most respondents disagreed with the proposition that: ‘ it is
possible to implement an AMT investment proposal based only on potential non-financial
benefits.’ It is clear that financial analysis is important, a range of financial indicators is usually
employed and most of these indicators are seen as important (discounted payback period being a
possible exception).
While hypothesis 5 concentrated on the choice of technique in relation to AMT, hypothesis 8
concentrated on criteria. Hypothesis 8, that the same criteria are applied to AMT as to other
investments, was supported. A picture of practice emerges where the same financial techniques
and financial criteria are applied to all investments whether AMT or not. As other researchers
have found, stringent criteria are often applied in practice and this survey supports previous
findings with short payback periods and relatively high discount rates being the norm.
It would be logical to conclude that AMT investment proposals are penalised by these
practices, supporting Kaplan’s (1986) question ‘Must AMT be justified by faith alone?’ and
Lefley’s (1994, p. 2758) assertion that: ‘… the use of [the] PB method of investment appraisal
practically guarantees rejection of AMT projects …’. Lefley continued: ‘… the payback method,
with its ‘short’ payback period, is inappropriate for projects such as AMT where the capital
expenditure is spread over a number of years, and the returns do not fully materialise until well
into the life or [of] the project.’
However, care must be exercised in reaching such conclusions because respondents did not
generally agree with the proposition: ‘It is difficult to get AMT investment proposals approved
because of stringent financial criteria.’ Traditional techniques are used and stringent financial
criteria applied but this does not necessarily mean that AMT proposals are more difficult to
approve than other investment proposals. One could speculate about the reasons for this finding.
Perhaps, contrary to expectations, AMT investments actually meet the criteria laid down; or
financial analysis is seen as a post hoc exercise to confirm an investment decision made on other
grounds; or the apparently high return demanded is offset when non-financial factors are taken
into account. This issue is considered next.
5.2. Non-financial criteria
Hypotheses 1, 3, and 9 relate to the evaluation of non-financial criteria in AMT investments.
Hypothesis 1 postulates increasing use of ‘strategic’ analysis and hypothesis 3 suggested that a
wide range of intangible benefits would be incorporated in such analysis. The first hypothesis
was supported and there was restricted support for hypothesis 3.
10
There was some evidence in support of hypothesis 9: that AMT investment is difficult to
justify because of failure to recognise all their intangible or non-financial benefits. Respondents
tended to agree that ‘some of the potential benefits of AMT are not taken into account because
they are difficult to express in financial terms.’ However, this is not conclusive, because the
omission of criteria such as ‘improved company image’, ‘employee morale’ and ‘experience
with new technology’ is not significant if such issues are judged unimportant- and many
respondents did not consider these ‘benefits’ to be important. It was surprising that ‘employee
morale’ was judged unimportant because other researchers (for example, Accola, 1994 and
Mensah and Miranti, 1989) have seen this as an important motivation for investing in AMT.
Table 6 suggests that at least eight non-financial criteria (or intangible factors) are considered
important in the evaluation process. Further analysis of the importance of intangible factors
across the three groups of companies indicated that these factors were seen as more important by
fully-integrated companies than by the other two groups (non-AMT and less-integrated
companies). The mean scores for almost all the intangible factors were higher for fully-integrated
companies than for the other two groups of companies (see table 6) and this supports the view of
Meredith and Hill (1987) who argued that the justification of higher levels of automation usually
needs more attention to intangible factors relative to economic justification. For four nonfinancial factors the Kruskal-Wallis one-way ANOVA indicated significant differences among
the three groups of companies and these factors may be the key ‘drivers’ behind many AMT
investments. Additionally, the intangible factor ‘requirements of customers’, is very important in
all groups of companies and indicates that firms should pay considerable attention to market
research during investment appraisal.
The importance of intangible factors in investment appraisal is confirmed by this survey and
specific factors are identified as important by the majority of respondents.
5.3. Risk measures (hypotheses 6 and 7)
The survey results indicate that sensitivity analysis is the most important technique for dealing
with investment project risk. This finding is consistent with the findings of Klammer et al.
(1991), Pike (1988) and Ho and Pike (1991).
A significant difference4 was found in the importance of sensitivity analysis among the three
groups of companies. It was less important in both less-integrated and fully-integrated companies
than non-AMT companies. This finding is consistent with that of Lefley (1994) who found a
reduction in the use of sensitivity analysis in assessing AMT investment project risk.
The widespread use of sensitivity analysis as evidenced by the current survey might be
attributed to its simplicity and the availability of computer packages which can help in applying
it in practice. Strictly, sensitivity analysis is not a technique of risk analysis at all, it merely
describes the sensitivity of key factors through their effect on the profitability of a project. It
gives an indication of the most sensitive variables but not their probability of occurrence. A
further limitation is the consideration of only one variable at once. (This could be overcome by
use of computer based simulation but this technique was considered important by only 11% of
respondents). This does not mean the technique is irrelevant but it does mean that it should only
be a first step in evaluating risk. Knowing the key sensitive factors, decision makers can then
estimate their variability and more sophisticated methods of risk analysis can then be undertaken.
Adjusting the required PB period according to the riskiness of a project was judged either
important or extremely important technique by only 40% of the respondents. This may appear
4
At 8% level of significance.
11
inconsistent with the earlier findings of Lefley (1994) who found 71.5% of respondents used this
method. However, Lefley’s respondents may use the technique without considering it especially
important and, when this is taken into account, the results of the two surveys can easily be
reconciled. The low percentage of respondents who consider adjusting the required payback
period as an important way of reflecting project risk may seem inconsistent with the high
importance given to payback as a financial appraisal technique but this provides evidence that
decision makers separate the two issues of financial evaluation and risk assessment.
In this survey, 70% of respondents in the non-AMT companies required payback in 3 years
or less while 76% and 83% of respondents in less-integrated and fully-integrated companies
respectively required this payback period. If shorter payback is required for higher risk
investments, it might be inferred that AMT investments are perceived to be riskier than other
investments. A similar inference could be drawn from the finding that higher discount or hurdle
rates are employed in both less-integrated and fully-integrated companies than in non-AMT
companies. While only 41% of respondents used 16% or more as a hurdle rate in non-AMT
companies, 53% and 60% of respondents used the same range in less-integrated and fullyintegrated companies respectively.
In general, the survey findings relating to risk analysis did not give a clear idea about how
practitioners deal with investment risks. Only sensitivity analysis and the use of conservative
cash flow estimates were considered important in dealing with risk by the majority of
respondents. The most preferred theoretical methods in evaluating investment risk: probability
analysis, CAPM and computer simulation, were judged to be important by very few respondents.
Furthermore, when respondents were asked to indicate the importance of the three possible
dimensions of risk suggested by Accola (1994) (the impact on company liquidity, the variability
of the project outcome, and the possibility of massive loss) only the impact on company liquidity
was rated important by over 50% of respondents.
6. Conclusion
A recurrent theme in the AMT literature is the strategic importance of such investments and
hence the need for a wider analysis when appraising them. Many researchers have developed
theoretical models designed to meet this perceived need by combining both financial and
strategic analyses. Such models range from simple combination of multiple attribute scores (e.g.
Parsaei and Wilhelm, 1989; Meredith and Suresh, 1986; Nelson, 1986) to the relatively
sophisticated analytic hierarchy process (e.g. Wabalickis, 1988; Ghosh and Wabalickis, 1991;
Putrus, 1990; Datta et al., 1992; O’Brien and Smith, 1993; Angelis and Lee, 1996) and the use of
‘strategic cost management’ analysis (e.g., Shank, 1996 and Carr and Tomkins, 1996).
The models in the literature usually either illustrate a particular algorithm (such as the
analytic hierarchy process) or a particular theoretical perspective (such as Porter’s strategic
analysis). Whilst many models do not have clear justifications, there are now a number of themes
in the AMT literature and these themes provided a basis for framing the hypotheses tested in this
research.
The results suggest that AMT investment decisions in practice do involve increasingly
‘strategic’ analysis but not at the expense of economic or financial analysis. ‘Intangible’,
‘strategic’, benefits such as customer requirements and consistency with corporate strategy are
important in investment decision making and four specific intangible benefits: ‘quality and
reliability of outputs’, ‘reduced lead-times’, ‘obtaining greater manufacturing flexibility’, and
‘reduced inventory levels’ are of particular significance in justifying AMT.
Several measures of financial return are considered to be important in practice and most
companies employ a ‘package’ of such measures (typically, payback, return on investment and
discounted cash flow measures) when evaluating investment projects. Practitioners appear to
make no distinction between AMT and other investments either in the techniques employed or in
12
the criteria used in decision making. The financial criteria employed seem quite stringent with
payback period of less than 3 years and discount/hurdle rate in excess of 10% per annum being
common.
It might seem logical to conclude that the difficulties of incorporating intangible benefits and
omission of some benefits together with stringent financial criteria would penalise AMT
investment proposals. There is evidence that this may be so but caution should be exercised in
drawing conclusions because practitioners do not appear to regard, some benefits (such as
‘improved company image’, ‘employee morale’ and ‘experience with new technology’) as
important - so their omission may not matter. And practitioners do not perceive gaining approval
for AMT investments to be more difficult than other investment proposals.
The findings provide practitioner support for a number of normative proposals in the
literature. Models which attempt to combine ‘financial’ and ‘strategic’ analyses would be
favoured as would the inclusion of several financial measures and certain, specific, ‘intangible’
benefits. Conversely, models which concentrate solely on financial or strategic analysis would
not be favoured and some ‘intangible’ benefits routinely incorporated in examples in the
literature would not normally be regarded as important by practitioners.
The survey suggests that the treatment of risk in practice is relatively naive. Sophisticated
techniques of risk analysis are not employed for AMT (or any other) investment project and the
only really popular technique is sensitivity analysis. Here a significant difference between
companies was found with the technique being rated most important by non-AMT companies!
In general the survey results provide confirmation of work by field researchers such as Nixon
(1995) and Slagmulder and Bruggeman (1992). Typically, practitioners adopt holistic
approaches incorporating both financial and strategic analyses in the evaluation of AMT
investment proposals. There is also support for Shank’s ‘strategic cost management’ (SCM)
analysis. Shank (1996) identified three SCM themes which ‘should’ be considered in AMT
appraisal: value chain analysis, cost driver analysis and competitive advantage analysis. These
three themes can readily be discerned in practitioners concern with: quality and reliability of
outputs and requirements of customers (value chain analysis); greater manufacturing flexibility,
reduced lead-times and reduced inventory levels (value chain analysis and cost driver analysis);
and keeping up with competition (competitive advantage analysis).
While this survey highlights practitioner concern with financial and strategic analyses it does
not necessarily indicate that such analyses are undertaken in a systematic manner. This provides
motivation for further research into the development of normative models which practitioners
would find acceptable. Multiple attribute, analytic hierarchy process and strategic cost
management models hold promise for this line of research.
The survey also suggests that the treatment of risk in practice would be a suitable topic for
further research. A series of interviews with nine of the survey respondents was undertaken in
order to both confirm the survey findings and to further investigate this topic. These interviews
did support the survey findings and, additionally, revealed that practitioners were not so
concerned with measuring project risk as with minimising it. The normative recommendations in
the literature appear to find little favour with practitioners and the development of models which
would be acceptable to practitioners and the (empirical) identification of ‘best practice’ would
also appear to be fruitful area for further research.

Project risk has a number of separate

H6: Practitioners consider three risk ‘dimensions’ to
be important: impact of the project on company
liquidity, variability of project outcomes, and
possibility of massive loss.
The large outlays involved in AMT investment

investments make AMT investments risky and
therefore sophisticated risk analysis techniques
‘should’ be employed in their evaluation.
