Here are the key inputs, tools and techniques, and outputs of the Estimate Activity Durations process:
Inputs:
- Activity list
- Enterprise environmental factors
- Organizational process assets
Tools and Techniques:
- Expert judgment
- Analogous estimating
- Parametric estimating
- Three-point estimating
Outputs:
- Activity duration estimates
- Basis of estimates
- Project documents updates
The primary output is the activity duration estimates, which are time estimates for completing individual activities based on factors such as resource availability, complexity, past experience, etc. These estimates are an important input for developing the project schedule.
