How to Build a Schedule Recovery Plan
A schedule recovery plan is a time-phased, resource-supported set of actions designed to restore an achievable contractual, program or internal milestone. It should identify the delay’s root cause, quantify its
Monthly IMS Status and Schedule Analysis Checklist
An effective IMS monthly status checklist does more than confirm that actual dates were entered. It verifies that the Integrated Master Schedule reflects current execution, produces a credible forecast and
P50 vs P80 Schedule Dates
In a P50 vs P80 schedule comparison, the P50 date has a 50 percent model-estimated probability of being met or improved. The P80 date has an 80 percent probability of
How to Identify Schedule Risk Drivers
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 vs Management Reserve
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
How Procurement Delays Propagate Through an IMS
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
Schedule Risk Analysis (SRA): Complete Guide
Schedule risk analysis estimates the probability that a program will meet a milestone or completion date. It applies uncertainty and discrete risks to a logic-driven schedule, runs many simulated outcomes
What Is Monte Carlo Schedule Risk Analysis?
Monte Carlo schedule risk analysis is a quantitative method for estimating the probability that a program will meet a completion date or interim milestone. Instead of treating every activity duration
Three-Point Duration Estimates: Optimistic, Most Likely, Pessimistic
A three point duration estimate defines a credible range for an activity using optimistic, most likely and pessimistic durations. Instead of assuming that one deterministic duration will occur, the three
