We have so far learnt how to construct project schedules using the CPM and PERT techniques. However, we assumed that all the resources needed to achieve that schedule will be available when needed. This is obviously not true. There might be fewer systems analysts or programmers available than needed to execute the project. And if even the actual number might be sufficient, the resource might not available in the specific time periods needed.
Projects compete with each other as well as with normal everyday organizational functions for resources. There are two main types of resources- the resources that are consumed and the ones that are not consumed.
The goal for this lesson is how to achieve your project management goals in the face of limited resources.
