Operations and maintenance[edit]
The deployment of the system includes changes and enhancements before the decommissioning or sunset of the system.Maintaining the system is an important aspect of SDLC. As key personnel change positions in the organization, new changes will be implemented. There are two approaches to system development; there is the traditional approach (structured) and object oriented. Information Engineering includes the traditional system approach, which is also called the structured analysis and design technique. The object oriented approach views the information system as a collection of objects that are integrated with each other to make a full and complete information system.
Evaluation[edit]
The final phase of the SDLC is to measure the effectiveness of the system and evaluate potential enhancements.
