- Processing to be carried out
- Deliverables
- Details of the file definitions
- A detailed time plan
- Designs of outputs, whether on screen, on paper, or by other methods
- The client is involved by telling you how they want the solution to look
- Installation and conversion
- Deliverables
- Fully functional solution, signed off by the client
- Fully documented including user guide and technical documents
- This is where the old system is surpassed by the new system
- The client is involved by seeing if the solution fits in with the environment and that it is up to their standards
- Deliverables
- Analysis
- What its strengths and weaknesses are
- Exactly what the existing system does
- What is required of the new system
- Any constraints that may be placed on the new system
- The client is involved by being part of the investigation part of analysis
- Review and maintance
- Corrective maintenance
- This means putting right any error reports once the system is up and running
- Adaptive maintenance
- This means altering the current system to meet any new client requirments
- Perfective maintenance
- This means tweaking the current system to sort out any inefficiencies
- Corrective maintenance
- Construction the solution
- Writing the code for the new system
- Deliverables
- Working system
- Documents of the solution
- Draft version of the user guide
- The client is involved by seeing if all the key parts of the solution are included
- Testing
- Integration testing
- When module testing is done modules are combined one at a time and then it is debugged
- Module testing
- Module testing means testing individual sections of software
- Functional testing
- This is used to pick up on any errors that went through module and integration testing
- It is also used to see if the new system meets the requirements of the client
- Systems testing
- This is where the users put it through its paces and then give feedback about the system
- User testing
- This is the final test before the system goes operational
- Give the system to the users in a controlled enviroment to see how the system copes in the field
- Operational testing
- This is conducted in an actual environment where the system will be in use
- Deliverables
- Test date and results
- Modified user guide
