a. Activity attributes
Identifying activity attributes is helpful for further selection and sorting of planned activities. They are used for schedule development, for report formatting purposes, and for selecting, ordering, and sorting planned schedule activities in various ways in reports. They extend the definition of activities by identifying multiple components associated with each activity. They include an activity identifier that is unique, the WBS identification number, and activity label or name. Once they are finished, they may include activity predecessors and successors, logical relationships, leads and lags, resource requirements, imposed dates, constraints and assumptions. They can be used to determine where the work has to be performed, the project calendar, the person responsible, and the type of activity involved.
