Planning & Scheduling Excellence Guide (PASEG)

Government Standards Reviewed by forProject Technology - updated Sep 2026
Quick definition: The Planning & Scheduling Excellence Guide (PASEG) is the NDIA Integrated Program Management Division's reference guide on building, using, and maintaining an Integrated Master Schedule.

The PASEG collects practical scheduling guidance from Government and Industry practitioners into a single reference, covering task naming, relationship logic, constraints, Working Calendars, Critical Path and Driving Path analysis, schedule risk, and execution metrics. It is written primarily for the DoD community, but the techniques apply to any scheduling tool or environment. It is guidance rather than a requirement — the PASEG is explicitly subordinate to whatever each program's contract specifies, and where a technique is contentious it points to the Generally Accepted Scheduling Principles (GASP), eight tenets describing a sound schedule. The current edition is Version 6, September 2025.

Why it matters

Much of the scheduling terminology in this encyclopedia traces back to the PASEG, which is the closest thing the defense scheduling community has to a common reference. Knowing it exists — and that it is guidance rather than contractual obligation — helps a team distinguish settled practice from local habit.

FAQ

Is following the PASEG a contractual requirement?
No. The PASEG is guidance and is subordinate to whatever each program's contract requires — which may include EIA-748, the EVMS Interpretation Guide, the IPMR or IPMDAR data item descriptions, and the contractor's own EVM System Description.
Who publishes the PASEG?
The NDIA Integrated Program Management Division (IPMD). It began as a 2009 NDIA scheduling Intent Guide draft, transferred to the NDIA Program Management Systems Committee in 2012, which was renamed the IPMD in 2014.
