Post Completion Audits (PCA). an important area in capital budgeting have not received much attention in the past. In a competitive environment, however, PCA plays an important role. Uncertain initial forecasts and current estimates can be revised using post audit information under a Bayesian approach at virtually no additional cost, thus enhancing future decisions. Prueitt and Park [2]. developed the Cash Flow Control Chart (CFCC) model for a special class of investment problems with multiple identical units with uncertain cash flows, typically found in Advanced Manufacturing Systems (AMS) and fleet replacement. This paper provides meaningful interpretations to modified Cash Row Control Chart (M-CFCC) patterns.
