Developing Information Systems
"The actions that are taken to create an information system that solves an organizational problem are called system development". These include system analysis, system design, programming/implementation, testing, conversion, production and finally maintenance. These actions usually take place in that specified order but some may need to repeat or be accomplished concurrently.
Conversion is the process of changing or converting the old system into the new. This can be done in three basic ways, though newer methods (prototyping, Extreme Programming, JAD, etc.) are replacing these traditional conversion methods in many cases:
- Direct cut – The new system replaces the old at an appointed time.
- Pilot study – Introducing the new system to a small portion of the operation to see how it fares. If good then the new system expands to the rest of the company.
- Phased approach – New system is introduced in stages.
