This system design phase includes the following steps: 1. The analyst should specify the file structures, storage devices etc. 2. The database is also designed in this phase. 3. Hardware cost, capability, speed, error rates, and other performance characteristics are specified. 4. Changes to be made in the organizational structure of the firm are outlined. 5. Input, output, files, forms and procedures are planned. 6. Finally, standards for testing, documentation and system control are formulate
According to Simon (1977), Intelligence, Design, And Choice, known as IDC are the phases of Decision making process. In the intelligence phase, decision situation is studied, figure out severity of problem, ownership of the problem. In the design phase, design of solutions for the problem is created. In the choice phase, one of the best solution from the different designed solutions are selected.
This would depend on what you are building. I would suggest that you start with all permits plans and design documents. You might also keep all design change and information documents as well. Add in all inspections and testing. Keep all purchase information through at least the warranty phase. This would be a good place to start. More complex projects will require better documentation.

The planning stage of the system development life cycle begins with a request to the system analyst.this is known as the system request.A system request is a describes a problem or desired changes to be made to an information system.this changes can be a minor or a major changes.A minor change inthe system involves a correction to the system interface or any other minor change within the system.whileas a major change refers to a replacement of an old information system with a new one to be able to cope with environmental changes. The planning phase deals with the following issues; .SYTEM REQUEST .FEASIBILITY STUDY .PRELIMINARY INVESTIGATIONS. PRELIMINARY INVESTIGATION For more;meatnealll@yahoo.com
