Create Project Management Tasks

In the Planning list, representing Planning Process Group, create the Estimate activity durations task with subtasks corresponding to the output of the Estimate Activity Durations process: Develop duration estimates, Develop basis of estimates, and Update project documents.

Create Project Management Documents

In the Docs section, create the Duration Estimates and Basis of Estimates documents.

Duration estimates are quantitative assessments of the likely number of time periods that are required to complete an activity, a phase, or a project. They do not include any lags.

In Basis of Estimates, supporting detail for duration estimates may include:

  • Documentation of the basis of the estimate
  • Documentation of all assumptions made
  • Documentation of any known constraints
  • Indication of the range of possible estimates
  • Indication of the confidence level of the final estimate
  • Documentation of individual project risks influencing this estimate
