Summary Activity Calculation Example
The scheduling values for a summary activity are calculated based on the information provided for its sub-activities (the “child” activities).Summary activity progress is tracked through each child activity. A summary activity is finished when all child activities have been marked complete.
For example, consider a summary activity that has four child activities:
|
Child Activity
|
Start
|
Finish
|
Duration
|
Work
|
% Work Complete
|
|
Activity 1
|
01-06-2017
|

Activity 2
|

|
01-24-2017
|

|

|
|
Activity 3
|
01-09-2017
|
02-05-2017
|
20 days
|
80 hours
|
25%
|
|
Activity 4
|
01-08-2017
|
01-10-2017
|
3 days
|
10 hours
|
100%
|
 |
The duration is the number of working days between the start and finish dates. This example uses a work week that extends Monday through Friday, with 40 hours of work per week.
|
As a result, the summary activity has the following values:
|
Start
|
Finish
|
Duration
|
Work
|
% Work Complete
|
|
01-06-2017
|
02-05-2017
|
23 days
|
170 hours
|

• Duration
The duration is calculated based on the number of working days between the earliest start date (01-06-2017) and the latest finish date (02-05-2017) from among the child activities.
• Work
The work is calculated based on the sum number of hours for all child activities.
• % Work Complete
Progress is weighted based on how much work each activity represents:
|
(Child Activity Work ÷ Total Work) * 100 = Percent of work that the child activity represents |
For example, Activity 4 represents 10 hours out of 170 hours of work:
|
(10 ÷ 170) * 100 = 5.8 |
Therefore, when Activity 4 is completed, 6% (rounded to the next whole number) is added to the percentage of work complete for the summary activity.
