Analysis - Precisely describing the problem in order to establish the users needs and solutions.

e.g of things that need improving - jobs where data needs to be more organised

- jobs which have to be done more quickly

- jobs which need better presentation

This is carried out by the systems analyst who determines:

1/ The user requirements

2/ Any failings of the current system

3/ Input data plus its source and output data plus its destination.

4/ The constraints on hardware, software and development time.

5/ Weather or not what the customer wants is what they really need

6/ Weather or not any proposed solution is feasible in reality

Research Methods

- Interview

- Questionnaire

- Observation

- Collecting Documentation used by business e.g invoices, bills etc..

- Researching similar business'.

Contents of Analysis

- Current system and any problems with it.

- Information requirements of the user. (required outputs) - (Input requirements)

- Feasibility study - technical feasibility - is technology available

- economical feasibility - are the development and running costs available

- legal feasibility - e.g does it breach data protection act

- social feasibility - e.g Might pose a health hazard

- Alternative solutions to the problem

- costs - hardware, software and paying

Design - Describing how the chosen solution will function
