The Systems Development Life Cycle: Implementation

The next phase is to actually create the components of the system and to convert from the old system to the new system The implementation phase consists of the following steps:

• Acquire the appropriate hardware and software
• Develop software
• Test the system — Testing should be an integral part of this phase, ensuring that each component works as it should and that the design plan is being followed.
• Write documentation
• Training
• Conversion — When development is complete, it's time to put the system in place. There are four main conversion methods — parallel, pilot, phased, and plunge.

Some authors refer to phased conversion as piecemeal conversion.

Although this topic discusses the implementation phase as part of the general systems development life cycle, this phase can be applied to developing an e-business solution for an organization.
