This is the final video in the Networks series for Further Maths. This is looking at the concept of Crashing. What is Crashing? Well, we look to try and complete a set of activities in a reduced amount of time by considering the activities on the critical path. When we reduce the length of time of the activities this can cost us money! So, we call it crashing with cost. I take a look at how we can crash the project and how we need to make sure, when we do crash, that we don't make new critical paths through the network.
