6.5 ESTIMATE ACTIVITY DURATIONS

Process Definition

This process determines the scheduled duration of each activity based on the scope and required resources to determine work effort and the number of work periods needed to complete each scheduled duration for each activity.

Process Assessment

Developing an activity estimate will help determine how long and the costs associated with each task and how long it will take to complete the project. By developing an activity duration estimate baseline a project can measure and improve upon processes to reduce time duration and costs.

Estimate Durations

6.5.1

Input

Scope Statement 611:

The scope statement as depicted in the ITD project in PGMT611, has two input constraints one is time and the other is cost.

6.5.2

Tools and Techniques

Three-point estimating 613:

This three-point estimate generated using QM software tool and Z-table to interpret three different duration scenarios of Optimistic time, Most likely time, Pessimistic duration and costs. This is a quick and dirty way to estimate duration activity estimates.

6.5.3

Output

Activity duration Estimates 501:

Created in PGMT 501, utilizes precedence duration diagramming and Excel to estimate an output activity duration and costs for several different scenarios.
