By Sivaraj Dhanasekaran
Schedule Network Analysis is one of the tools and techniques of Schedule Development process. Critical Chain Method is one of the method used to perform Schedule Network Analysis.
This method is used to prepare the project schedule when limited or restricted resources are available.
In this method, the PM usually schedule all or most of the high risk or critical activities in the earlier stage of the project schedule. This allows the critical tasks to be completed early as well as gives buffers to handle unexpected problems if arises. Also the PM will combine several tasks in to one task and assign one resource to handle all.
The steps involved:
- Construct the Schedule Network Diagram
- Define dependencies
- Define constraints
- Calculate critical path for the project
- Apply resource availability
The critical path will change once the resource availability has been applied.
