Cost Variance Analysis: How to Identify and Explain Cost Deviations

1. What is Cost Variance Analysis and Why is it Important?

cost variance analysis is a process of comparing the actual cost of a project or activity with the planned or budgeted cost. It helps to identify and explain the reasons for any deviations from the expected cost, such as overruns or savings. Cost variance analysis is important for several reasons:

- It helps to monitor and control the project performance and ensure that it is on track with the scope, schedule, and quality objectives.

- It helps to identify and mitigate any risks or issues that may affect the project cost, such as changes in scope, delays, errors, or inefficiencies.

- It helps to communicate the project status and progress to the stakeholders, such as sponsors, clients, or management, and justify any corrective actions or changes that may be required.

- It helps to improve the project planning and estimation process by learning from the past experience and applying the best practices and lessons learned.

To perform a cost variance analysis, the following steps are usually involved:

1. Collect and organize the cost data for the project or activity, such as the actual cost incurred, the planned or budgeted cost, and the earned value (the value of the work completed).

2. calculate the cost variance (CV), which is the difference between the actual cost and the planned cost. A positive CV indicates a cost saving, while a negative CV indicates a cost overrun.

3. calculate the cost performance index (CPI), which is the ratio of the earned value to the actual cost. A CPI greater than 1 indicates a cost efficiency, while a CPI less than 1 indicates a cost inefficiency.

4. analyze the cost variance and the cost performance index to identify the root causes and the impact of the cost deviations. Some of the common factors that may cause cost variance are:

- Scope changes: Changes in the project scope may increase or decrease the cost of the project, depending on the nature and extent of the changes.

- Schedule changes: Changes in the project schedule may affect the cost of the project, as some costs are time-dependent, such as labor, materials, or equipment.

- Quality changes: Changes in the project quality may influence the cost of the project, as higher quality may require more resources, time, or effort, while lower quality may result in rework, defects, or customer dissatisfaction.

- Resource changes: Changes in the project resources, such as human, material, or equipment, may alter the cost of the project, as different resources may have different costs, availability, or productivity.

- External factors: Factors outside the project control, such as market conditions, inflation, exchange rates, or regulations, may affect the cost of the project, as they may change the prices, availability, or demand of the project inputs or outputs.

5. report and communicate the cost variance analysis results to the relevant stakeholders, such as the project team, sponsors, clients, or management, and provide recommendations or suggestions for improving the project cost performance or addressing any issues or risks that may arise.

6. Implement any corrective actions or changes that may be necessary or agreed upon to bring the project cost back on track or optimize the project cost performance.

For example, suppose a project has a planned cost of $100,000 and an actual cost of $120,000 at a certain point of time. The earned value of the project at that point is $80,000. The cost variance analysis for this project would be:

- CV = Actual Cost - Planned Cost = $120,000 - $100,000 = -$20,000

- CPI = earned Value / Actual cost = $80,000 / $120,000 = 0.67

- The cost variance analysis shows that the project has a cost overrun of $20,000 and a cost inefficiency of 0.67. This means that the project is spending more than planned and delivering less value than expected. Some of the possible causes for this situation are:

- The project scope may have increased or changed without adjusting the budget accordingly.

- The project schedule may have been delayed or extended due to unforeseen circumstances or poor planning.

- The project quality may have been compromised or lowered due to errors, defects, or rework.

- The project resources may have been insufficient, unavailable, or unproductive due to shortages, turnover, or conflicts.

- The project may have been affected by external factors, such as inflation, currency fluctuations, or regulatory changes.

- The cost variance analysis results should be reported and communicated to the stakeholders, along with the explanations and recommendations for improving the project cost performance or resolving any issues or risks. Some of the possible actions or changes that may be implemented are:

- The project scope may be revised or clarified to align with the budget and the expectations of the stakeholders.

- The project schedule may be updated or optimized to reduce the duration or the cost of the project.

- The project quality may be improved or enhanced by implementing quality assurance or quality control measures, such as testing, inspection, or feedback.

- The project resources may be increased, replaced, or trained to improve the availability, productivity, or efficiency of the project team or the project inputs or outputs.

- The project may be adjusted or adapted to cope with the external factors, such as hedging, negotiating, or complying with the market conditions, exchange rates, or regulations.

It almost goes without saying that when you are a startup, one of the first things you do is you start setting aside money to defend yourself from patent lawsuits, because any successful company, even moderately successful, is going to get hit by a patent lawsuit from someone who's just trying to look for a payout.

2. How to Calculate the Difference Between Actual and Budgeted Costs?

In this section, we will delve into the concept of cost variance and explore how to calculate the difference between actual and budgeted costs. Cost variance is a crucial metric in financial analysis, as it helps organizations assess the effectiveness of their budgeting and cost control processes.

To begin, let's examine cost variance from different perspectives. From a project management standpoint, cost variance measures the variance between the actual costs incurred during a project and the budgeted costs. It provides insights into whether a project is over or under budget and helps identify areas where cost-saving measures can be implemented.

Now, let's move on to the calculation of cost variance. The formula for calculating cost variance is relatively straightforward. It involves subtracting the budgeted costs from the actual costs. The resulting value indicates whether the project is over or under budget.

Here is the formula for cost variance:

Cost Variance = actual costs - Budgeted Costs

For example, let's say a project has a budgeted cost of $10,000, but the actual costs incurred amount to $12,000. By applying the cost variance formula, we can calculate the cost variance as follows:

Cost Variance = $12,000 - $10,000 = $2,000

A positive cost variance indicates that the actual costs are higher than the budgeted costs, suggesting that the project is over budget. Conversely, a negative cost variance implies that the actual costs are lower than the budgeted costs, indicating that the project is under budget.

To provide a more comprehensive understanding, let's explore some scenarios where cost variance analysis can be applied:

1. identifying Cost overruns: Cost variance analysis helps identify projects or activities that are exceeding their budgeted costs. By pinpointing these cost overruns, organizations can take corrective actions to bring the project back on track.

2. Assessing Cost Control Measures: cost variance analysis enables organizations to evaluate the effectiveness of their cost control measures. By comparing the actual costs with the budgeted costs, organizations can identify areas where cost-saving initiatives have been successful and areas that require further attention.

3. project Performance evaluation: Cost variance analysis plays a vital role in evaluating project performance. By analyzing cost variances across different projects, organizations can identify patterns and trends, enabling them to make informed decisions for future projects.

Cost variance analysis is a valuable tool for assessing the financial performance of projects and activities. By calculating the difference between actual and budgeted costs, organizations can gain insights into cost overruns, evaluate cost control measures, and make data-driven decisions.

3. A Case Study of a Project with Cost Deviations

In this section, we will look at a cost variance analysis example of a project that experienced cost deviations from its planned budget. We will examine the causes and effects of the cost variances, as well as the corrective actions taken by the project manager and the project team. We will also discuss the lessons learned from this case study and how they can be applied to other projects. cost variance analysis is a useful tool for monitoring and controlling the project performance and ensuring that the project objectives are met within the allocated resources.

The project we will analyze is a software development project that aimed to deliver a new application for a client in the banking sector. The project had a duration of six months and a budget of $500,000. The project followed the agile methodology and used the earned value management (EVM) technique to measure the project progress and performance. The project had four main phases: initiation, planning, execution, and closure. The project team consisted of 10 software developers, two testers, one project manager, and one business analyst.

The project faced several challenges and risks that resulted in cost deviations from the planned budget. Some of the main factors that contributed to the cost variances were:

- Scope changes: The client requested several changes and additions to the project scope during the execution phase, which increased the project complexity and required more resources and time to complete.

- Quality issues: The project team encountered some technical difficulties and bugs in the software development process, which affected the quality of the deliverables and caused rework and delays.

- Resource turnover: The project team experienced a high turnover rate of software developers, which reduced the productivity and efficiency of the team and increased the training and hiring costs.

- Communication breakdown: The project team had poor communication and coordination with the client and the stakeholders, which led to misunderstandings and conflicts and affected the project performance and satisfaction.

The project manager and the project team used the cost variance analysis to identify and explain the cost deviations and to take corrective actions to bring the project back on track. The cost variance analysis involved the following steps:

1. Calculating the earned value (EV), the actual cost (AC), and the planned value (PV) of the project at each reporting period. The EV is the value of the work completed, the AC is the cost incurred, and the PV is the budgeted cost of the work scheduled.

2. Calculating the cost variance (CV) and the cost performance index (CPI) of the project at each reporting period. The CV is the difference between the EV and the AC, and the CPI is the ratio of the EV to the AC. The CV and the CPI indicate whether the project is under budget or over budget.

3. analyzing the causes and effects of the cost variances and determining the root causes of the problems. The project manager and the project team used various tools and techniques, such as the fishbone diagram, the Pareto chart, and the 5 whys, to identify the factors that contributed to the cost deviations and to assess their impact on the project performance and objectives.

4. Taking corrective actions to address the cost variances and to improve the project performance. The project manager and the project team implemented various measures, such as negotiating the scope changes with the client, improving the quality assurance and testing processes, retaining and motivating the project team members, and enhancing the communication and collaboration with the client and the stakeholders, to reduce the cost deviations and to ensure the project success.

The project was completed with a total cost of $550,000, which was 10% higher than the planned budget. The project delivered the expected quality and functionality to the client, but with a slight delay of two weeks. The project achieved a customer satisfaction rating of 8 out of 10. The project manager and the project team conducted a lessons learned session at the end of the project and documented the best practices and the improvement areas for future projects.

The cost variance analysis example of this project shows how cost variance analysis can help project managers and project teams to monitor and control the project costs and to take corrective actions to ensure the project success. Cost variance analysis can also provide valuable insights and learnings for improving the project management processes and practices and for avoiding or minimizing the cost deviations in future projects. Cost variance analysis is a powerful tool for project management that can help project managers and project teams to deliver successful projects within the budget constraints.

4. How to Identify the Factors that Lead to Cost Overruns or Underruns?

One of the most important aspects of cost variance analysis is to identify and explain the causes of cost deviations. Cost variance causes are the factors that lead to cost overruns or underruns, which are the differences between the actual and planned costs of a project or activity. Cost variance causes can be classified into two main categories: internal and external. Internal causes are those that are within the control or influence of the project manager or the project team, such as scope changes, resource allocation, quality issues, or estimation errors. External causes are those that are outside the control or influence of the project manager or the project team, such as market fluctuations, regulatory changes, natural disasters, or force majeure events. In this section, we will discuss how to identify and explain the cost variance causes from different perspectives, such as the project sponsor, the project manager, the project team, and the stakeholders. We will also provide some examples of common cost variance causes and how to address them.

Some of the steps to identify and explain the cost variance causes are:

1. Review the cost variance report. The cost variance report is a document that summarizes the actual and planned costs of a project or activity, and calculates the cost variance and the cost performance index (CPI). The cost variance report can help to identify the areas or elements of the project or activity that have the highest or lowest cost deviations, and the overall performance of the project or activity in terms of cost. The cost variance report can also provide some clues or indicators of the possible cost variance causes, such as the status of the project or activity, the changes in the scope, the availability of the resources, the quality of the deliverables, or the external factors that affect the project or activity.

2. Analyze the cost variance causes. The analysis of the cost variance causes involves digging deeper into the root causes of the cost deviations, and understanding the reasons and the impacts of the cost variance causes. The analysis of the cost variance causes can be done using various tools and techniques, such as the cause-and-effect diagram, the 5 whys technique, the Pareto chart, or the fishbone diagram. The analysis of the cost variance causes can help to determine the nature and the source of the cost variance causes, whether they are internal or external, controllable or uncontrollable, preventable or unavoidable, or positive or negative.

3. Explain the cost variance causes. The explanation of the cost variance causes involves communicating the findings and the results of the analysis of the cost variance causes to the relevant parties, such as the project sponsor, the project manager, the project team, and the stakeholders. The explanation of the cost variance causes can be done using various formats and methods, such as the cost variance analysis report, the cost variance dashboard, the cost variance presentation, or the cost variance meeting. The explanation of the cost variance causes should be clear, concise, accurate, and objective, and should include the following information: the summary of the cost variance report, the description of the cost variance causes, the impacts of the cost variance causes, the actions taken or planned to address the cost variance causes, and the recommendations or suggestions to improve the cost performance of the project or activity.

Some of the examples of common cost variance causes and how to address them are:

- Scope changes. Scope changes are the modifications or additions to the original scope of the project or activity, which can affect the cost of the project or activity. Scope changes can be caused by various factors, such as the changes in the requirements, the expectations, the preferences, or the needs of the project sponsor, the project manager, the project team, or the stakeholders. Scope changes can lead to cost overruns or underruns, depending on the nature and the magnitude of the scope changes. To address the scope changes, the project manager or the project team should follow a formal and documented change management process, which should include the following steps: identify the scope change, evaluate the scope change, approve or reject the scope change, implement the scope change, and update the cost baseline and the cost variance report accordingly.

- Resource allocation. resource allocation is the process of assigning and managing the resources of the project or activity, such as the human resources, the material resources, the equipment resources, or the financial resources. Resource allocation can affect the cost of the project or activity, as the resources have different costs and availability. Resource allocation can be influenced by various factors, such as the availability of the resources, the demand of the resources, the quality of the resources, or the conflicts of the resources. resource allocation can lead to cost overruns or underruns, depending on the efficiency and the effectiveness of the resource allocation. To address the resource allocation, the project manager or the project team should follow a systematic and realistic resource management process, which should include the following steps: estimate the resource requirements, plan the resource allocation, execute the resource allocation, monitor and control the resource allocation, and update the cost baseline and the cost variance report accordingly.

- Quality issues. Quality issues are the problems or defects that affect the quality of the deliverables or the outcomes of the project or activity, such as the functionality, the reliability, the usability, or the satisfaction of the deliverables or the outcomes. Quality issues can impact the cost of the project or activity, as the quality issues can result in rework, waste, delays, or customer complaints. Quality issues can be caused by various factors, such as the lack of quality standards, the lack of quality control, the lack of quality assurance, or the lack of quality improvement. Quality issues can lead to cost overruns or underruns, depending on the severity and the frequency of the quality issues. To address the quality issues, the project manager or the project team should follow a comprehensive and continuous quality management process, which should include the following steps: define the quality expectations, plan the quality activities, perform the quality activities, measure and evaluate the quality performance, and update the cost baseline and the cost variance report accordingly.

5. How to Present and Communicate the Cost Variance Results to Stakeholders?

A cost variance report is a document that summarizes the differences between the actual and planned costs of a project. It helps project managers and stakeholders to understand the reasons for the cost deviations, the impact of the deviations on the project performance, and the corrective actions that need to be taken to bring the project back on track. A cost variance report is an essential tool for effective project cost management and communication.

However, preparing and presenting a cost variance report is not a simple task. It requires careful analysis, clear explanation, and strategic communication. Project managers and cost analysts need to consider the following aspects when creating and delivering a cost variance report:

1. The audience and the purpose of the report. Different stakeholders may have different expectations and interests in the cost variance report. For example, senior executives may want to see the big picture and the bottom line, while functional managers may want to see the details and the root causes. Therefore, the report should be tailored to the specific audience and the purpose of the report. The report should also highlight the key messages and the main takeaways for the stakeholders.

2. The format and the structure of the report. The cost variance report should be organized and presented in a logical and consistent way. The report should include the following elements: an executive summary, a cost variance overview, a cost variance analysis, and a cost variance action plan. The executive summary should provide a brief overview of the project status, the cost variance results, and the main recommendations. The cost variance overview should provide a graphical and numerical representation of the cost variance data, such as a cost performance index (CPI), a cost variance (CV), and a cost variance percentage (CV%). The cost variance analysis should explain the causes and the effects of the cost deviations, such as scope changes, schedule delays, resource issues, quality problems, or external factors. The cost variance action plan should outline the corrective and preventive actions that need to be taken to address the cost deviations, such as revising the budget, adjusting the scope, rescheduling the activities, reallocating the resources, or negotiating with the suppliers or the customers.

3. The tone and the style of the report. The cost variance report should be written and spoken in a professional and respectful manner. The report should avoid blaming, criticizing, or accusing anyone for the cost deviations. Instead, the report should focus on the facts, the evidence, and the solutions. The report should also use clear, concise, and precise language, avoiding jargon, acronyms, or technical terms that may confuse or alienate the stakeholders. The report should also use positive and constructive words, such as "opportunities", "improvements", or "lessons learned", rather than negative and defensive words, such as "problems", "failures", or "mistakes".

4. The delivery and the feedback of the report. The cost variance report should be delivered and communicated to the stakeholders in a timely and appropriate manner. The report should be shared with the stakeholders before the presentation, so that they can review and prepare for the discussion. The presentation should be scheduled and conducted in a suitable setting, such as a meeting room, a conference call, or a webinar. The presentation should also be interactive and engaging, allowing the stakeholders to ask questions, share opinions, or provide suggestions. The presentation should also be followed by a feedback session, where the project manager and the cost analyst can solicit and address the feedback from the stakeholders, such as their concerns, their expectations, or their satisfaction.

By following these guidelines, project managers and cost analysts can create and present a cost variance report that is informative, persuasive, and actionable. A cost variance report that is well-prepared and well-delivered can help project managers and stakeholders to improve the project performance, to enhance the project communication, and to achieve the project success.

6. How to Develop and Implement Corrective Measures to Control Costs?

cost variance is the difference between the actual cost and the planned or budgeted cost of a project or activity. It can be positive or negative, indicating that the project is over or under budget, respectively. Cost variance analysis is the process of identifying and explaining the reasons for the cost deviations, and taking corrective actions to bring the project back on track. In this section, we will focus on the cost variance action plan, which is the set of steps and measures that a project manager or a business owner can take to control the costs and minimize the negative impact of cost variance.

A cost variance action plan should be developed and implemented as soon as possible, after the cost variance analysis has been done and the root causes of the cost deviations have been identified. The action plan should be realistic, feasible, and aligned with the project objectives and scope. It should also be communicated and agreed upon by all the relevant stakeholders, such as the project team, the sponsors, the clients, and the suppliers. The action plan should include the following elements:

1. The cost variance goals and targets. These are the specific and measurable outcomes that the action plan aims to achieve, such as reducing the cost variance by a certain percentage or amount, or bringing the project within the budget limit by a certain date. The goals and targets should be SMART: Specific, Measurable, Achievable, Relevant, and Time-bound.

2. The cost control strategies and tactics. These are the specific actions and methods that will be used to achieve the cost variance goals and targets. They can be classified into two types: preventive and corrective. Preventive strategies are those that aim to avoid or reduce the occurrence of cost variance in the future, such as improving the project planning and estimation, implementing effective change management and risk management, and negotiating better contracts and prices with the suppliers. Corrective strategies are those that aim to fix or mitigate the existing cost variance, such as reducing the project scope or quality, reallocating or optimizing the resources, and seeking additional funding or revenue sources.

3. The cost control responsibilities and accountabilities. These are the roles and tasks that each stakeholder or team member has to perform to execute the cost control strategies and tactics. They should be clearly defined and assigned, and the expectations and deliverables should be communicated and agreed upon. The responsibilities and accountabilities should also be monitored and evaluated regularly, and feedback and recognition should be provided.

4. The cost control tools and techniques. These are the tools and techniques that will be used to support the cost control strategies and tactics, such as cost management software, cost reports and dashboards, cost performance indicators and metrics, cost audits and reviews, and cost variance contingency plans. The tools and techniques should be selected and applied appropriately, and the results and outcomes should be analyzed and reported.

For example, suppose that a project has a budget of $100,000 and a planned duration of 12 months. After six months, the project has spent $70,000 and has completed 50% of the work. The cost variance is $10,000, or 10%, which means that the project is over budget. The cost variance analysis reveals that the main causes of the cost deviation are inaccurate estimation, scope creep, and unexpected delays. The project manager decides to develop and implement a cost variance action plan, which includes the following elements:

- The cost variance goal is to reduce the cost variance to 5% or less by the end of the project, and to complete the project within the budget limit of $100,000.

- The cost control strategies are to revise the project plan and estimate, to implement stricter change control and approval processes, to accelerate the project schedule by using the critical path method and crashing techniques, and to negotiate a discount with the supplier for the remaining materials.

- The cost control responsibilities are to assign the project planner to update the project plan and estimate, to assign the project sponsor to approve any change requests, to assign the project team to work on the critical path activities and to report any issues or risks, and to assign the project manager to negotiate with the supplier and to monitor and control the project cost performance.

- The cost control tools are to use a cost management software to track and forecast the project cost, to use a cost report and dashboard to display the cost variance and performance indicators, to use the earned value management technique to measure the project progress and performance, to use a cost audit and review to verify and validate the project cost, and to use a cost variance contingency plan to prepare for any potential cost deviations.

By developing and implementing this cost variance action plan, the project manager hopes to control the costs and minimize the negative impact of cost variance on the project success.

7. How to Avoid Common Mistakes and Pitfalls in Cost Variance Analysis?

Cost variance analysis is a useful tool for monitoring and controlling the performance of a project or a business. It helps to identify and explain the differences between the actual costs and the planned or budgeted costs of a project or a business activity. However, cost variance analysis is not without its challenges and limitations. There are some common mistakes and pitfalls that can affect the accuracy, reliability, and usefulness of cost variance analysis. In this section, we will discuss some of these mistakes and pitfalls and how to avoid them. We will also provide some best practices and tips for conducting a successful and effective cost variance analysis.

Some of the common mistakes and pitfalls in cost variance analysis are:

1. Using inappropriate or inaccurate cost data. Cost variance analysis relies on the quality and accuracy of the cost data that is used for comparison. If the cost data is outdated, incomplete, inconsistent, or inaccurate, the cost variance analysis will produce misleading or erroneous results. For example, if the actual costs are based on different accounting methods, currency rates, or inflation rates than the planned or budgeted costs, the cost variance analysis will not reflect the true performance of the project or the business. To avoid this mistake, it is important to use cost data that is relevant, reliable, and comparable for cost variance analysis. The cost data should be collected and reported in a consistent and standardized way, using the same accounting principles, currency rates, and inflation rates. The cost data should also be updated and verified regularly to ensure its accuracy and validity.

2. Ignoring or misinterpreting the causes of cost variances. Cost variance analysis is not only about calculating the differences between the actual and planned or budgeted costs, but also about understanding and explaining the reasons behind those differences. Ignoring or misinterpreting the causes of cost variances can lead to incorrect or ineffective decisions and actions. For example, if a positive cost variance (actual cost is lower than planned or budgeted cost) is attributed to a favorable market condition, rather than to a cost-saving initiative, the project or business may miss an opportunity to replicate or sustain the cost performance. Conversely, if a negative cost variance (actual cost is higher than planned or budgeted cost) is attributed to an unavoidable external factor, rather than to a poor management or execution, the project or business may fail to address or correct the cost issue. To avoid this mistake, it is important to conduct a thorough and objective analysis of the causes of cost variances. The analysis should consider both internal and external factors, such as changes in scope, quality, schedule, resources, risks, assumptions, market conditions, customer requirements, and stakeholder expectations. The analysis should also distinguish between controllable and uncontrollable factors, and between one-time and recurring factors, to determine the appropriate and feasible actions and recommendations.

3. Focusing only on the total or aggregate cost variance. Cost variance analysis can be performed at different levels of detail, such as by project, by activity, by resource, by category, or by period. Focusing only on the total or aggregate cost variance can obscure or overlook the significant or meaningful cost variances that occur at the lower levels of detail. For example, if the total cost variance of a project is zero or negligible, it may imply that the project is on budget and performing well. However, this may hide the fact that some activities or resources are over budget and underperforming, while others are under budget and overperforming, resulting in a net zero or negligible cost variance. This can prevent the project from identifying and addressing the cost problems or opportunities that exist at the lower levels of detail. To avoid this mistake, it is important to perform cost variance analysis at different levels of detail, depending on the purpose and scope of the analysis. The cost variance analysis should drill down to the level of detail that provides the most relevant and useful information for decision making and action taking. The cost variance analysis should also highlight and explain the significant or meaningful cost variances that occur at any level of detail, and their implications and impacts on the project or business performance.

9. How to Benefit from Cost Variance Analysis and Improve Project Performance?

Cost variance analysis is a powerful tool for project managers to monitor and control the budget and performance of their projects. By comparing the actual costs with the planned or budgeted costs, project managers can identify and explain the causes of cost deviations, and take corrective actions to prevent or minimize them in the future. Cost variance analysis can also help project managers to communicate the project status and progress to the stakeholders, and justify any changes or requests for additional resources. In this section, we will discuss how to benefit from cost variance analysis and improve project performance from different perspectives, such as project scope, quality, schedule, risk, and stakeholder satisfaction. We will also provide some tips and examples on how to conduct cost variance analysis effectively and efficiently.

Here are some ways to benefit from cost variance analysis and improve project performance:

1. Align project scope with budget and expectations. One of the main reasons for cost variance is the mismatch between the project scope and the budget. Project scope defines the work that needs to be done to deliver the project deliverables and meet the project objectives. Budget is the estimated amount of money that is allocated for the project. Expectations are the desired outcomes and benefits that the project stakeholders expect from the project. Cost variance analysis can help project managers to align the project scope with the budget and expectations by identifying and quantifying the scope changes, and assessing their impact on the cost and value of the project. For example, if a project manager finds out that the actual cost is higher than the planned cost due to an increase in the project scope, he or she can use cost variance analysis to evaluate whether the scope change is justified by the increase in the project value, and whether it is approved by the project sponsor and the key stakeholders. If not, the project manager can use cost variance analysis to negotiate and agree on the scope change, or request for additional budget or resources to accommodate the scope change.

2. Ensure project quality and customer satisfaction. Another reason for cost variance is the variation in the project quality and customer satisfaction. Project quality is the degree to which the project deliverables and processes meet the quality standards and requirements. Customer satisfaction is the extent to which the project deliverables and processes meet or exceed the customer expectations and needs. Cost variance analysis can help project managers to ensure project quality and customer satisfaction by measuring and comparing the actual quality and customer feedback with the planned or expected quality and customer satisfaction. For example, if a project manager finds out that the actual cost is lower than the planned cost due to a decrease in the project quality, he or she can use cost variance analysis to determine the root causes of the quality issues, and implement corrective actions to improve the quality and prevent further defects or errors. Alternatively, if a project manager finds out that the actual cost is higher than the planned cost due to an increase in the customer satisfaction, he or she can use cost variance analysis to validate the customer feedback and satisfaction, and leverage the positive results to enhance the project reputation and relationship with the customer.

3. Optimize project schedule and resources. A third reason for cost variance is the deviation in the project schedule and resources. Project schedule is the planned sequence and duration of the project activities and milestones. Resources are the people, equipment, materials, and other assets that are needed to perform the project activities. Cost variance analysis can help project managers to optimize project schedule and resources by tracking and analyzing the actual time and effort spent on the project activities and tasks, and comparing them with the planned or estimated time and effort. For example, if a project manager finds out that the actual cost is higher than the planned cost due to a delay in the project schedule, he or she can use cost variance analysis to identify and address the factors that caused the delay, such as resource constraints, dependencies, risks, or changes. Similarly, if a project manager finds out that the actual cost is lower than the planned cost due to an acceleration in the project schedule, he or she can use cost variance analysis to verify and document the reasons for the acceleration, such as resource availability, efficiency, or innovation.

4. Manage project risks and uncertainties. A fourth reason for cost variance is the occurrence of project risks and uncertainties. Project risks are the events or conditions that have a negative impact on the project objectives, such as cost, quality, schedule, or scope. Uncertainties are the events or conditions that have an unknown impact on the project objectives, such as market changes, technological changes, or regulatory changes. Cost variance analysis can help project managers to manage project risks and uncertainties by identifying and evaluating the actual and potential effects of the risks and uncertainties on the project cost and performance, and implementing appropriate responses to mitigate or exploit them. For example, if a project manager finds out that the actual cost is higher than the planned cost due to a risk occurrence, he or she can use cost variance analysis to assess the severity and probability of the risk, and determine the best response strategy, such as avoidance, reduction, transfer, or acceptance. Conversely, if a project manager finds out that the actual cost is lower than the planned cost due to an uncertainty occurrence, he or she can use cost variance analysis to estimate the magnitude and likelihood of the uncertainty, and decide the best response strategy, such as exploitation, enhancement, sharing, or retention.

5. Improve project communication and reporting. A fifth reason for cost variance is the lack or excess of project communication and reporting. project communication is the exchange of information and knowledge among the project stakeholders, such as project team, sponsor, customer, and suppliers. Project reporting is the presentation and dissemination of project information and data, such as project status, progress, performance, and issues. Cost variance analysis can help project managers to improve project communication and reporting by providing a clear and consistent framework and format for collecting, analyzing, and presenting the project cost and performance data, and highlighting the key findings and recommendations. For example, if a project manager finds out that the actual cost is different from the planned cost, he or she can use cost variance analysis to generate a comprehensive and concise report that shows the cost variance, the cost performance index, the cost variance percentage, the cost variance explanation, and the cost variance action plan. The project manager can then use the report to communicate and report the project cost and performance to the relevant stakeholders, and solicit their feedback and support.
