Graphical Evaluation and Review Technique

<p>Graphical Evaluation and Review Technique (GERT) is a <a href="/facts/Network_theory/m6CQovwm">network analysis</a> technique used in <a href="/facts/Project_management/JgQVSU3o">project management</a> that allows probabilistic treatment both network logic and estimation of activity duration. The technique was first described in 1966 by <a href="/facts/Alan_Pritsker/d4AHqHU1">Dr. Alan B. Pritsker</a> of Purdue University and WW Happ.
</p><p>Compared to other techniques, GERT is only rarely used in complex systems. Nevertheless, the GERT approach addresses the majority of the limitations associated with <a href="/facts/Program_Evaluation_and_Review_Technique/TVTWehCE">PERT</a>/<a href="/facts/Critical_path_method/cl8LtYqY">CPM</a> technique. GERT allows loops between tasks. The fundamental drawback associated with the GERT technique is the complex programme (<a href="/facts/Monte_Carlo_method/AkHjY7jc">Monte Carlo simulation</a>) required to model the GERT system. Development in GERT includes Q-GERTS - allowing the user to consider queuing within the system.
