Legacy Issue Number: 18718
Source: InterCAX ( Lonnie VanZandt)
According to the definition of ProjectSequence, "MODAF: Asserts that one ActualProject (MODAF::Project) follows from another - i.e. the target ActualProject cannot start until the source ActualProject has ended. DoDAF: NA".
The restriction "...cannot start until the source ActualProject has ended..." precludes practical project management.
In practice, projects can have a partial ordering yet not be strictly sequential. Projects can overlap each other in time, occurring partially contemporaneously.
One sees, in a common tool such as Microsoft Project, the ability to specify Start to Start, Finish to Finish, Start to Finish, and Finish to Start offsets.
Recommended Remedy: Enhance Project Sequencing to support SS, FF, SF, and FS offsets between prior and next ActualProjects. The kind of offset and the duration of the offset would each be Tag Values of ProjectSequence.
