Systems Life Cycle

1. Analysis

   • Collect information and identify problems
     • Observation
     • Questionnaries
     • Interviews
     • Looking at documents

2. Design

   • Designing a new system and correcting problems
     • Make the design clear
     • Use text boxes
     • Use of tick boxes (to make choiches)
     • Use clear fonts and clear text colours

3. Development & Testing

   • Development and testing of the new system

4. Implementation

   • Replacing the old system
     • Methods of changeover
       • Direct
       • Parallel
       • Pilot
       • Phased

5. Documentation

   • Creating technical and user documentation
     • How to use the software
       • How to load/install
       • How to save files
       • How to add/delete
       • How to log in/out
       • Software/Hardware requirements
       • Glossary of terms

6. Evaluation

   • Evaluating if the new system complete the requirements
     • Compare the final task with the original
     • Interview users
     • Compare test results from the new system with the old one
     • Identify posible improvemnents
