Each task has a duration of 9 days to complete 90 production-units of work.
This is illustrated by the simple project below, where tasks A, B, and C are sequentially performed between Start and Finish milestones. In terms of a project schedule, this kind of relationship is most easily modeled as Finish-to-Start with a negative lag (aka “lead”). The most common front-end planning occurrence of these relationship in my experience is in logic driven summary schedules, where analysis of the underlying detailed logic indicates that the start of a successor summary activity is closely associated with, but before, the approaching finish of its summary predecessor. In general, the possibility of modest overlap exists at many Finish-Start relationships in detailed project schedules, sometimes being implemented as part of a fast-tracking exercise. In engineering/design, many follow-on tasks may be allowed to proceed after key design attributes are “frozen” at some point near the finish of the predecessor task. Real-world examples of such overlap include the cleanup/de-mob and mob/setup stages of sequential tasks in construction projects.
In practice, Runner 2 establishes a mark on the track – paced backward from the exchange zone – and starts his own run when Runner 1 reaches the mark. Runner 2 does not care about Runner 1’s fast start nor his awkward stumble at the midway point his only focus is on gauging Runner 1’s finishing speed and starting his own run at the precise instant necessary to match speeds in the transition zone. At the end of Leg 1, Runner 2 must start running before Runner 1 arrives, timing his acceleration to ensure an in-stride passing of the baton in the exchange zone, simultaneous with the completion of Leg 1. Overlapping tasks with Finish-Start Transition relationships can be described in terms of a relay (foot)race, where an exchange zone for handing over the baton exists between each pair of “legs” (i.e. There are essentially two categories of overlapping task relationships: Finish-Start Transitions and Progressive-Feeds. Nevertheless, they remain the most effective tools for accurately modeling the plan of work in many cases. These items were not supported in the original Critical Path Method (CPM), and some scheduling guidelines and specifications still prohibit or discourage their use. Handling the second condition typically requires the use of time lags and logic relationships that are not Finish-to-Start.
