Kerry has just completed an estimate for his project. In his estimate, he’s come to the conclusion that this project should be completed by his target date based on the fact that there are many repetitious activities, which should take less time to complete as time goes on, thereby shortening the last leg of the project. What answer best addresses the estimating technique that Kerry used?
Explanation
Answer: b - The type of estimating that Kerry used is best represented by the Learning Curve approach under Parametric Estimating, which looks at historical info and tries to project completion times, taking into account improvements to the process. One-time estimating involves using one estimate per activity. Analogous estimating involves using similar projects as a basis for an estimate. Three-Point estimating involves using three estimates per activity creating a range.
Key Take Away: Advanced project managers may tend to favor one estimating technique over another, but as with other things in life, it’s important to expand your horizons, and constantly explore other ways of doing things that may prove to be more effective.
