Generally Accepted Scheduling Principles (GASP)
The Generally Accepted Scheduling Principles (GASP) are eight
over-arching tenets for building, maintaining, and using schedules as
effective management tools.
The GASP is concise and easily understood, yet set high expectations
for program management teams to develop and use schedules.
The first five GASP tenets describe the requisite qualities of a valid
schedule; that is, one that provides complete, reasonable, and credible
information based on realistic logic, durations, and dates.
The latter three GASP tenets reflect increased scheduling maturity
that yields an effective schedule.
An effective schedule provides timely and reliable data, aligns
time-phased resources, and is built and maintained using controlled
and repeatable processes.
The GASP serves several purposes. First, they are high level tenets,
or targets, for sound scheduling. The GASP also serves as a validation
tool for the program team or organization to assess schedule maturity
or schedule areas needing improvement.
Lastly, the GASP can be used as a governance tool to assess new or
different scheduling approaches with objectivity and detachment.
Achieving a GASP-compliant schedule indicates the schedule is not
merely healthy, but fit.
A healthy schedule is functional and meets minimum management
purposes, but a fit schedule is robust and dynamic.
A fit schedule provides the program team with a program execution
roadmap of meaningful progress and realistic forecasts against a
resource-loaded performance measurement baseline.
Thus, meeting all eight GASP tenets demonstrates that the program
team builds and maintains the schedule with rigor and discipline so
that the IMS remains a meaningful management tool from program
start through completion.
