The Stages Problem Statement What is the current situation? What are the problems with current situation? What are the requirements of the new website (which will solve the problem)? How will the website solve the problem? Details of any data inputs, processing and output which will occur.

The Problem Statement This is a statement which informs you of what the problem is which the website aims to solve, Should be a short statement – which the rest of the analysis document will explore, If you are doing this unit in connection with g048 then you should use the brief as your problem statement.

The Current System This will describe the current working practices of the organisation which the website will replace, If the website for example is to encourage sales then you would describe how the company currently trades, If the website is for promotion or raise awareness then you will describe how they currently do this.

Problems With Current System List of issues which the current ways of working provide, These could be minor irritations or major floors which are seriously hindering efficiency, Each issue needs to be explained.

Website Requirements List of requirements for the new website so that it solves the current problem and meets the needs of the organisation, Can be also described as the “success criteria” of the site which will be looked at again during evaluation, Could be a mix of simple requirements and more complex ones The website must have the address clearly displayed The website must have a way of displaying products so customers can view them, then purchase them A note should be added to each requirement explaining how it solves the problems identified.
