Activities in a project typically require the use of resources such as people, material, equipment and working capital. The schedule for the activities that we had calculated in the previous module assumes that adequate resources are available as and when required. However, in practice often adequate resources may not be available as required and the schedule may have to be modified. There are two types of problems when resource requirements are considered. One is the Resource Smoothing Problem and the other is the Resource Limitation problem. In the first one, i.e. the Resource Smoothing Problem, although the resources are available as and when required, we would want to find a schedule that “smoothes” the use of resources without delaying the project completion time. Critical Chain Project Management (CCPM) is the next topic dealt with in this module. CCPM has not gained universal acceptance although it is being used by some organizations with positive results. CCPM places a lot of emphasis on aggressive estimation of activity durations and provides for buffers to take care of some delays. With Risk Management, we first define what risk is and then discuss the risk management process including risk identification, risk assessment and various ways of reducing exposure to risk. Risk monitoring and control including change control process are also covered. Finally, the Program Evaluation and Review Technique (PERT) including a simulation approach to finding the distribution of the project completion time is covered as the last topic in this module. As in the previous modules, towards the end of this module, we present some practical aspects pertaining to the concepts covered. This again is done through a Q & A format with Mr. Prashun Dutta, Advisor - Gaiga Smart Cities
