6.4 ESTIMATE ACTIVITY DURATIONS

Estimate Activity Durations is the process of estimating the number of work periods needed to complete individual 

activities with estimated resources. The key benefit of this process is that it provides the amount of time each activity 

will take to complete. This process is performed throughout the project. The inputs, tools and techniques, and outputs of 

this process are depicted in Figure 6-12. Figure 6-13 depicts the data flow diagram of the process.
