Program Evaluation and Review Technique
The Program Evaluation and Review Technique
commonly abbreviated PERT
is a model for project management
invented by United States Department of Defense
's US Navy Special Projects Office in 1958
as part of the Polaris
launch project. This project was a direct response to the Sputnik crisis
This project model was the first of its kind, a revival for scientific management, founded in fordism and taylorism. Though every company now have their own "project model" of some kind, they all resemble PERT in some respect. Only DuPont corporations critical path method was invented at roughly the same time as PERT.
The most famous part of PERT is the "PERT Networks", charts of timelines that interconnect. PERT is intended for very large-scale, one-time, complex, non-routine projects.
