Schedule slippage is an unfortunate reality for many large development programs. The Australian Defence Materiel Organisation Schedule Compliance Risk Assessment Methodology (SCRAM) provides a framework for identifying and communicating the root causes of schedule slippage and recommendations for going forward to Program and Executive-level management. It is based on a repeatable process that uses a root cause analysis of schedule slippage model to locate factors that impact program schedule along with a “health check” of the documented schedule, assessing its preparation and probability distribution of completion dates. SCRAM can be used at the commencement of a program to validate a proposed schedule and identify potential risks, during program execution as a “health check”, or as a diagnostic tool to identify root causes when schedule slippage occurs. To date, SCRAM has been applied to a number of major development acquisition programs in Australia and the United States. According to one documented report, seventy-eight percent of US Department of Defense Programs have experienced some form of schedule slippage . Schedule slippage is a symptom of any number of problems or causes occurring on a project.
