| # Activity Relationships (tppss2510m000) Use this session to define and maintain activity relationships. The activities must be sequenced accurately to provide realistic schedules. An activity relationship is a logical relationship indicating that a certain activity (successor) cannot start or end until another activity (predecessor) starts or ends. The predecessor or successor activity can also be a milestone activity. One cannot link the same predecessor task twice to same successor task and one cannot link the same predecessor task to the same successor task. You cannot create, edit or delete a relationship for projects with Finished/ Closed/ Archived status. Project The code that identifies the project. Description The description or name of the code. Status The status of the project. Plan The code that identifies the plan. Description The description or name of the code. First Free Number The first free number to be used in the activity relationship series. When you define a new series, you must enter the series' starting number. LN increases the number by one each time a number is issued. Predecessor Activity The activity which initiates the relationship. Description The description or name of the code. Predecessor Cost Type Select the cost type associated with the activity for which the budget is maintained. Pred.Budget LineNo. The budget line generated for the selected cost type. Successor Activity The activity linked to the predecessor activity. The activity cannot start or end until the predecessor activity starts or ends based on the value of the Relationship Type field. Successor Cost Type Select the cost type associated with the activity for which the budget is maintained. Succ.Budget Line No. The budget line generated for the selected cost type. Relationship Type Select the relationship type to define the dependencies between the predecessor and successor activities. Following are the possible values: Finish-to-Start The initiation of the task of the successor depends upon the completion of the task of the predecessor. Finish-to-Finish The completion of the task of the successor depends upon the completion of the task of the predecessor. Start-to-Start The initiation of the task of the successor depends upon the initiation of the task of the predecessor. Start-to-Finish The completion of the task of the successor depends upon the initiation of the task of the predecessor. Lead/Lag Lead time is the overlap between activities that have a dependency. You enter lead time as a negative value. Example, if an activity can start when its predecessor is half completed, you can specify a finish-to-start dependency with a lead time of 50 per cent for the successor task. Lag time is a delay between activities that have a dependency. You enter lag time as a positive value. Example if you need a two-day delay between the finish of one activity and the start of another, you can establish a finish-to-start dependency and specify the lag time as two days. Lead/Lag Unit The unit of time. Relationship Established The check box is selected automatically, when the relationship is established in MS Project. Print Activity Relationships Prints the activity relationships and the related data. |
