Give examples of activities in the lifecycle phases of desig

Give examples of activities in the life-cycle phases of design, implementation, and operation. Why does the discontinuity of life-cycle phases cause stress in an organization? Give examples of how the stress might manifest itself. System implementation relies heavily on good planning. List several examples of plans that need to be developed to ensure a smooth system implementation.

Solution

Design:

-->During this phase, functional, support and training requirements are translated into preliminary and detailed designs.
--> Decisions are made to address how the system will meet functional requirements.
--> A preliminary (general) system design, emphasizing the functional features of the system, is produced as a high-level guide.
-->Then a final (detailed) system design is produced that expands the design by specifying all the technical detail needed to develop the system.

Implementation:

--> During this phase, the new or enhanced system is installed in the production environment, users are trained, data is converted (as needed),
the system is turned over to the sponsor, and business processes are evaluated.
-->This phase includes efforts required to implement, resolve system problems identified during the implementation process,
and plan for sustainment.

Operation:

-->The system becomes operational during this phase.
-->The emphasis during this phase is to ensure that sponsor needs continue to be met and that the system continues to perform according to specifications.
-->Routine hardware and software maintenance and upgrades are performed to ensure effective system operations.
-->User training continues during this phase, as needed, to acquaint new users to the system or to introduce new features to current users.
-->Additional user support is provided, as an ongoing activity, to help resolve reported problems.
