Complete Guide on Cost Variance Analysis for PMP Exam
Cost Variance Analysis is a fundamental part of cost management in project management. It pertains to the PMBOK Guide Seventh Edition.
Why is it important?
It helps in assessing the efficiency of cost performance of any project. It enables project managers to understand if they are over or under the budget, which is crucial for project success.
What is it?
Cost variance analysis is measuring the cost performance by comparing the budgeted costs of work performed (earned value), with the actual cost of the work performed. A negative cost variance means the project is over budget and a positive variance indicates the project is under budget.
How does it work?
Cost Variance (CV) is calculated by subtracting the actual cost (AC) from the earned value (EV). The formula is CV = EV - AC.
Answering exam questions on Cost Variance Analysis:
1. Understand the difference between a negative and positive variance.
2. Remember the Cost Variance formula and understand how to use it.
3. Ensure to read the question carefully before choosing the answer.
4. Practice as many questions as possible on cost variance, to solidify your understanding.
Exam Tips: In the exam, you could be given a scenario and asked to calculate the cost variance. Always remember that negative variance means the project is over budget and a positive one means it's under budget.
