Concept of Paths and Path Segments
Momentum Science has identified two new components within the Critical Path Method Schedule, that have always been there … just never defined: Activity Path and Activity Path Segment.
Under Dominant Project Management, there is only the Activity (at one end of the spectrum) and the overall Schedule (at the other end of the spectrum). There is nothing in between. Even the infamous “Critical Path” is only defined as a set of activities leading from Project (Schedule) Start to Project (Schedule) Finish. We have not found one Dominant Project Management book that actually defined the word, “path.”
By comparison, Momentum Management provides a clear definition of what constitutes an Activity Path. In fact, it goes further … by defining Path Ends, Path Start, and Path Finish (including the conditions necessary to qualify as each). It further clarifies the overlapping nature of Activity Paths, resulting in individual activities actually residing on multiple Activity Paths at the same time.
Finally, it defines a new term, Activity Path Segment, to help us isolate a subset of activities along a single Activity Path that have no intervening or interfering connections, except between the activities one to another, in serial order..
Application of Path and Path Segment Designations
With the establishment of these intermediate Work Scope Containers, for the first time work performance can be planned, executed, monitored, and analyzed with greater granularity that the Overall Project, but without getting into the minutia of activity-by-activity comparisons (as is now the common practice under Dominant Project Management). Said bluntly, Activity Paths and Path Segments allow us to still be able to spot the forest from the trees.
