A driving predecessor is an immediate predecessor that currently determines the start or finish date of its successor through schedule logic. If the driving predecessor moves later, the successor will
The difference between hard vs soft constraints is how severely each one restricts a schedule’s response to network logic. In a forward-scheduled network, a soft constraint prevents an activity from
Schedule leads can damage schedule quality because they allow a successor to start before its predecessor reaches the event defined by the relationship. That overlap may look efficient. However, it
Schedule lags are appropriate when a relationship requires a real, measurable passage of time and no work, resources, or meaningful progress occurs during that interval. A fixed curing, drying, cooling,
Out of sequence progress occurs when an activity reports actual progress even though the predecessor condition defined in the schedule has not been satisfied. For example, a successor may start
To trace the Microsoft Project critical path, start at the project completion milestone and follow its driving predecessors backward through the schedule. Use the Critical Tasks format to see critical
The DCMA 14 point assessment is a set of schedule metrics used to examine the structure, status and execution performance of an Integrated Master Schedule (IMS). It checks areas such
Schedule risk drivers are the activities, risk events, uncertainties and network paths that have the greatest influence on a target milestone or program finish date. You identify them by running
Schedule margin and management reserve address different dimensions of program risk. Schedule margin is an allowance of time placed at strategic points in a schedule. Management reserve (MR) is budget
Procurement schedule delays propagate through an Integrated Master Schedule (IMS) when a late purchase, approval, fabrication step or delivery pushes logically connected downstream work. The delay may first consume available
