Variance Analysis
Variance Analysis is a technique used in project management to identify and analyze the differences between planned and actual project performance, particularly concerning the project scope, time and cost. It involves comparing the planned work, costs or schedule against the actual progress, identifying deviations or variances, tracing the causes behind these variances and determining appropriate corrective actions. Variance analysis helps to monitor the project performance, mitigate risks, improve resource allocation, and ensure that the project stays on track towards achieving its objectives. It also provides valuable insights for future projects, enabling organizations to continuously improve their project management processes and practices.
Guide: Variance Analysis in Project Management
Variance Analysis is a crucial concept in the PMBOK Guide Seventh Edition. It is a quantitative investigation of the difference between actual and planned behavior. This analysis helps to maintain control over a project's scope by managing potential and actual changes to the elaborated scope statement.
The importance of Variance Analysis lies in its utilization for explaining the performance efficiency, the cause of the variance, and potential adjustments needed. For instance, if a project is running behind schedule or exceeding its allocated budget, variance analysis can help identify the reason behind this and what actions are necessary to realign the project with its initial plan.
