•to demonstrate an ability to produce data and process models

Outline of the task :

The assignment requires you to play the role of a systems analyst. You are required to analyse the current situation and to develop a systems requirements specification.

You should ensure that the development of a new logical solution addresses the problems of the current situation, and where possible addresses new business needs and opportunities for the client.
