The systems development life cycle (SDLC) is the overall process for developing information systems, from planning and analysis through implementation and maintenance.

Pilot implementation installs the new system in phases (for example by department) until it is verified that it works correctly.

Projects are typically dynamic in nature, and change should be expected and anticipated for successful project completion.

The implementation phase involves taking all of the detailed design documents from the design phase and transforming them into the actual system.

One way to support users’ questions is to create a help desk, or a group of people who respond to users’ questions.

Detailed user documentation is created that highlights how to use the system and how to troubleshoot issues or problems.

Post-implementation reports are formal reports or audits of a project after it is up and running.

Discovery prototyping builds a small-scale representation or working model of the system to ensure that it meets the user and business requirements.

Plunge implementation discards the legacy system completely and immediately migrates all users to the new system.

Loose coupling is the capability of services to be joined together on demand to create composite services, or disassembled just as easily into their functional component.
