An Integrated Master Schedule (IMS) is a logic-driven model of the work required to complete a program. It connects activities, milestones, dependencies, and authorized scope from program start through completion.
To understand how to build an integrated master schedule, start with the work rather than the scheduling software. Define the program scope, organize it through the Work Breakdown Structure (WBS),
The difference between an Integrated Master Plan and an Integrated Master Schedule is straightforward: the IMP defines the event-driven criteria for program success, while the IMS defines the time-phased work
An effective IMS WBS structure uses the Work Breakdown Structure (WBS) to organize schedule scope by product or deliverable. Detailed activities sit beneath the applicable WBS elements and work packages,
An effective IMS schedule status process records what happened, forecasts the remaining work and calculates the effect on contractual milestones. Set a common status date, collect actual starts and finishes,
The IMS status date is the cutoff date through which the Integrated Master Schedule reflects actual progress. It separates recorded performance from the forecast for remaining work. Schedulers also call
IMS critical path analysis identifies the sequence of remaining activities that drives a program completion date or another key milestone. To perform it correctly, update the Integrated Master Schedule (IMS)
A near critical path schedule review identifies sequences of work that could soon control a program completion date or key milestone. These paths have more total float than the current
An effective IMS schedule review confirms more than whether the file opens and passes a metric screen. Before customer delivery, the scheduler should verify contractual compliance, status integrity, network logic,
