Building an Analysis Schedule – Lessons Learned from the SGSS Program

Methods and Models I Track



Constructing an integrated cost and schedule uncertainty model involves bringing together important program elements: cost, risk, and schedule. The model’s core is the schedule; the linking of costs and risks to the schedule is what allows the implementation of time-dependent costs and, ultimately, an analysis that jointly considers cost and schedule. It follows, then, that one of the first, and often largest, difficulties in constructing an integrated cost and schedule model is the development of the schedule backbone.
Modern program master schedules (e.g., Integrated Master Schedules-IMS) are typically massive and labyrinthine. This presentation covers an approach for developing an analysis schedule that is directly informed by an IMS, but is not purely derived from summation of the activities. This highlights a key enable in that an analysis schedule does not need to be a rote summarization of the IMS. This presentation will cover the key attributes of an analysis schedule and how it can be constructed from high-level knowledge of program work flows and other available data.
