This article presents a diagnostic review of the PERT (Program Evaluation and Review Technique) technique, and defines the technique and outlines some of the problematic aspects of designing a PERT Cost system that may have an impact on schedule and cost performance. The author discusses observations on the construction of proposal networks and pitfalls in networking, such as the sophistry of the black boxes, the vendor nose constraining the vertical fin design, grouping of engineering releases, waiting time, the reversal of constraints, acceptable level of technical risk, and updating of subsidiary networks. He reminds users of the PERT technique that a sound, synthesized system design is complex and necessitates adherence to the prescribed procedures.
