System development lifecycle

Discussion Points

For this discussion complete the following:

• Choose two types of testing techniques and compare them.

Implementation Phase and System Maintenance Phases

As we conclude the Design Phase, we move into the System Implementation Phase and then Systems Maintenance phase.

Implementation Phase

After the system passes acceptance testing, the project then moves to the Systems Implementation phase.  In this phase, the software will be handed off to the users.  If necessary, training will also be provided to the users on the new system.  Sometimes the new system will run in tandem with the old system for a while, to ensure a smooth transition.  If this is not possible, then it can be prudent to roll out the new software in stages, to minimize risk.

Major Deliverable: Installed System, Test Plan, Programs, documentation, Migration Plan, Support Plan, Problem Report, Change Request, Post-Implementation Audit Report

System Maintenance Phase

After the new system has been implemented and put into production, the Systems Maintenance Phase begins.  During this phase, the system is monitored and any minor problems or bugs that are discovered by the users are fixed.  Improvements are made to both software and hardware to fix bugs, improve performance, address security issues, and implement user requirements. Periodic reviews may also be scheduled to ensure that the system is functioning as intended.  System patches are installed. Major enhancements may trigger a mini SDLC process which restarts the SDLC. At some point the system may be replaced with major enhancements.

Major Deliverable:  Updated System, Report on Process Reviews and User Satisfaction, Security Certifications

Course Objectives(s)

• CO5: Discuss the implementation phase of the SDLC, programming the system, testing, and documentation
