2. Structuring the method around functional analysis

2.1 Using functional specifications

During preliminary studies, the project is defined very succinctly. You will be familiar with :

• the basic need ;

• main function(s) ;

• some secondary functions ;

• major constraints.

The analogical method is there to help you estimate the cost on the basis of these basic assumptions alone.

To do this, you need to familiarize yourself with the functional specifications of the product to be developed. This helps you to identify the functional requirements of the final product, and provides some quantitative data to help you determine the complexity...
