Since projects can vary considerably, there are few hard-and-fast rules about the contents of activities or how long they can last. Activities in a production line, for example, might last a day or two, while activities in a large development project might have durations of many months or even years.
In general, most activities share the following characteristics:
A definite duration
Logical relationships to other activities in a project
Resources such as people, materials, or facilities
It is a good idea to keep these characteristics in mind when defining activities. By breaking a project down into a set of discrete activities with relatively limited durations, it is possible to establish more objective, and thus more accurate, estimates of progress.
When you insert activities on the change details form, a unique activity ID is created automatically and cannot be changed. The ID will start with the letters ACT and will be a parent ID.
When a change request has Change Details included on the form and allows creating, editing, and deleting of activities, the change can only be associated with a single project.
If the PM Compass project is associated with many Open Plan projects, you must select a control account on the change request form. In addition, all activities in the control account must come from one of the Open Plan projects.
If the selection on the change request form includes activities from more than one Open Plan project, the following error message is displays when you click the Change Details button:
“The selected project and/or control account has activities coming from more than one Open Plan project. Your selections on the change request form must be associated with a single Open Plan project."
