Graphical Evaluation and Review Technique (GERT)
- GERT allows probabilistic treatment of both the network logic and estimation of duration for completing the activity, following a randomly determined sequence of observations.
- This technique is similar to PERT, but it allows both deterministic and nondeterministic (probabilistic) branching in a network.
- GERT allows to having loops between activities in a network.
- Though GERT addresses the major limitations of other scheduling techniques like CPM and PERT, it is very rarely used in complex systems.
Advantages of GERT:
- Addresses the limitations of other scheduling techniques
- Allows non-deterministic sequences in execution.
Disadvantages of GERT:
- Complex algorithm required to model the GERT system
- GERT has not gained popularity. It is very rarely used

Graphical Evaluation and Review Technique, commonly known as GERT, is ...
Graphical Evaluation and Review Technique (GERT) is a network analysis technique used in project management. It is commonly used to analyze and evaluate complex projects that involve uncertainty and probabilistic factors. GERT allows for the analysis of general stochastic networks, the probabilistic treatment of both network logic and estimation of activity duration.
Key Points:
- GERT is a network analysis technique used in project management.
- It allows for the analysis of general stochastic networks.
- It provides a probabilistic treatment of both network logic and estimation of activity duration.
Analysis of General Stochastic Networks:
- GERT enables the analysis of general stochastic networks, which are networks that involve probabilistic factors and uncertainty.
- This means that GERT can handle projects where the duration of activities or the sequence of events is uncertain or variable.
- It allows for the modeling and evaluation of complex projects that involve random events or variations in activity durations.
Probabilistic Treatment of Network Logic:
- GERT provides a probabilistic treatment of network logic, which means that it takes into account the uncertainties and probabilities associated with different paths and events in the project.
- It allows for the consideration of different scenarios and probabilistic outcomes in the project schedule.
- This helps project managers to assess the potential risks and uncertainties associated with a project and make informed decisions.
Estimation of Activity Duration:
- GERT also enables the estimation of activity duration in a probabilistic manner.
- Instead of providing a single duration estimate for each activity, GERT allows for the consideration of a range of possible durations along with their associated probabilities.
- This provides a more realistic representation of the project schedule and allows for a better understanding of the potential variations in project completion time.
Identification of Minimum Time to Complete the Project:
- One of the key objectives of GERT is to identify the minimum time needed to complete the total project.
- By considering the uncertainties and probabilistic factors, GERT helps project managers to identify the critical path and the activities that have the most impact on the project duration.
- This information can be used to optimize the project schedule and allocate resources effectively.
In conclusion, GERT is a powerful network analysis technique used in project management. It allows for the analysis of general stochastic networks, the probabilistic treatment of network logic, and the estimation of activity duration. By considering uncertainties and probabilistic factors, GERT helps project managers to evaluate complex projects and make informed decisions.
