CPA Stage 1 The data collection

The team will:

  1. identify all the activities needed for the project's completion. You will not be required to do this in this course, or in the examination, as the nature of the activities and their duration will be provided or you will be given a complete network and asked to manipulate it. This is probably the most important part of CPA, the collection of the data.
  2. identify the dependencies, if any, between activities - in other words which activities must be completed, before other activities can start. Again, you will be given this information.

Imagine you are making a cup of tea. Some activities need to be done CONSECUTIVELY, i.e. one after the other. Clearly it wouldn't be sensible to pour hot water onto the tea bag until it is in a cup! An activity that follows another is said to be consecutive; it depends on the previous activity being complete before it can start. For example a roof cannot be put on a building until the walls are finished.

However, some activities do not rely on others; they can be done whilst others activities are in progress, e.g. you can get the cup out of the cupboard, whilst the kettle is boiling. These activities can run CONCURRENTLY (together).

It is important to know whether activities are consecutive or concurrent, as this affects the duration of the project and planning of the resource use.

A judge sentences a criminal to a three-year sentence for burglary, and a four-year

term for violence. These are to run consecutively. He is also sentenced to two years

prison for another burglary, which is to run concurrently. How many years in total

will the criminal serve?
