The practicalities of PERT

This paper indicates that PERT has not been as successful as its potential actually warrants. It is suggested that the practical aspects of PERT have been neglected in favor of the theoretical aspects, and that as a result PERT implementation efforts have in many cases failed. Seven basic implementation and operation errors are identified and discussed as being the keys to PERT failures. In addition an implementation network is included which depicts the tasks and logic required for a successful PERT implementation.
