Core TSIs : Projects : Working with Projects : Defining the effort for project activities
Defining the effort for project activities
Procedure
1. Go to Projects > Project items.
2. Select the project activity (WBS item) for which you want to define the effort.
3. Go to the Effort field and enter a value using the period picker. The effort can be defined in minutes, hours, days, weeks, or months.
If a project calendar is linked: effort is calculated based on the defined working hours (for example: 09:00–17:00, Monday to Friday).
If no calendar is linked: effort is calculated using continuous time—24 hours a day, 7 days a week.
