Recurrent information systems (IS) problems, including low quality, long development lead times, user dissatisfaction, and high implementation costs have been a persistent theme in the IS literature and have led to the perception of a "software crisis". Consequently, the IS development community has adopted several software process improvement (SPI) programs supported by formal process assessment approaches such as the capability maturity model (CMM). Research, conducted mostly in developed countries to evaluate the effects of such programs, has confirmed that an SPI focus can contribute to the production of high-quality systems; however, this phenomenon has rarely been studied in smaller enterprises such as those in Jamaica and other developing countries. The insights gleaned from such research in larger organisations may not be entirely applicable to the smaller firms in Jamaica. The authors undertook a survey of Jamaican organisations which revealed the absence of any f...

The objective of the conference was to explore, uncover and impart a deeper understanding of applied strategies for enhancing the competitiveness of Jamaican firms, society and economy for successful participation in the Global Knowledge Economy, in support of Jamaica’s national development; and more generally, the transformation of the economy of the Caribbean region from low-cost, natural-resource-based to an innovation-driven powerhouse. Immense interest had been expressed in this very important and timely topic, by a variety of sectors, firms, trade unions and members of academia and the media, as the country continues the debate on growth strategies, grounded in our yet untapped unique human potential. The issues and policies related to two critical knowledge economy pillars, education and innovation, and the nexus between both, provided the capacity and capability for powerful and important synergies. The role of knowledge management and knowledge management systems and their ...

ABSTRACT The information system (IS) discipline has been plagued by the absence of agreed definitions of the numerous terminologies that are used throughout the range of processes and activities employed to deliver applications for productive use. This lack of agreement also has constraining implications for cumulative research in the discipline. In this paper, we propose a solution to the problem that involves the development of a formal IS domain ontology using a methodology that focuses on ensuring the completeness and consistency of the ontology. The ontology provides a mechanism for standardising the vocabulary in the domain, classifying concepts and terms, representing relationships, identifying synonyms and homonyms, and it identifies the instances of these concepts and relationships. Our solution will facilitate knowledge sharing in the information systems community and further scholarly activities which require a deeper understanding of the structure of information in this domain.

ABSTRACT The theories of social exchange, task-technology fit, and technology acceptance are utilized in a field study of software development methodologies. This investigation includes the effects of user experiences on perceptions of acceptance and usage of a methodology. More specifically, perceptions of the outputs and deliverables from a methodology and perceptions of challenges and obstacles to using and applying a methodology were found to significantly and positively influence perceived usefulness and negatively influence ease of use of a methodology, respectively, within a developer's organization. Perceived usefulness was a positive and strong antecedent to perceptions of fit between the methodology and client problems, and the strengthening of efficacy beliefs about the methodology.
