The designed software may require integration with the outer entities. For example, there may be the need for integration with databases, libraries, and other programs.
Implementation entails installation of the software on user computers. Notably, software is tested for portability. At the same time, Integration and adaptability related problems are dealt with at the implementation stage. On other occasions, the software may require post- installation configurations at the user end.
Software Operation and Maintenance
This is in terms of fewer errors and enhanced efficiency. Importantly, it might require training of users on how to operate and ensure that they maintain the software operational. In order to, maintain the software operationally, coding updates are required. This depends on technological changes and/or changes in the user end environment. In most cases, this stage/phase is faced with challenges from anonymous problems and unknown defects.
