The document is a transcript from an April 16th, 2011 AACE Symposium workshop about performance measurement baselines. The speaker defines a performance measurement baseline as a time-phased budget plan for accomplishing work that is used to measure project performance. It includes budgets assigned to scheduled work and their spreads, as well as indirect budgets derived from a resource loaded master schedule contained in work packages. The speaker notes that connecting four key words - credible, performance, measurement, and baseline - can increase the probability of project success.
