Final answer:
Zero cost variance is not always good for a project. It does not guarantee project success or efficiency.
Step-by-step explanation:
Zero cost variance is not always good for a project. Cost variance measures the difference between the actual cost of completing an activity or project and the planned cost. A zero cost variance means that the actual cost matches the planned cost, indicating that the project is on track. However, this does not necessarily mean that the project is successful or efficient.
For example, if the planned cost was too high and the actual cost matches it, it means that the project may have been over-budgeted and there was no cost-saving achieved. On the other hand, if the planned cost was too low and the actual cost matches it, it means that the project may have been under-budgeted and there was no allowance for any unforeseen expenses.
Therefore, while zero cost variance can be an indicator of good planning and execution, it does not guarantee project success or efficiency. It is important to consider other factors such as the quality of deliverables, timeliness, and customer satisfaction.
