The System Development Life Cycle Use/Evaluation phase Revision is to ensure that all work or procedures perforn are to the best.
Parallel systems: as the name suggests, this is where two systems (the current and the new ones) are run at the same time to preform the same job. While this duplicates the work, there are some significant advantages to this type of system. As the performance of the existing system is a known quantity, it gives the developers something to compare the performance and accuracy of the new system to. The trial system: this is where a small version of the system is set up and trialed before the widespread introduction of the system. This trial emulates all aspects of the computer system to ensure that they work properly. It aims to reproduce as closely as possible the "real life" situation the system will be used in. Where the new system requires the old hardware and/or software to be removed, and it is not possible to have a cutover program or parallel systems, then the use of a trial system has significant benefits. HELPFUL AND UNDERSTOOD.

In order to make the system a success it must be able to produce the outcomes that can solve the problem that has been identified. Therefore the output required needs to be outlined early in the process. Once output has been identified it places constraints on the system. While it may sound minor, the manner in which output is to be created and/or displayed is actually of great significance to the design of a computer system and therefore it must be identified as early as possible.
Adaptation is one aspect that we should think about when we talk about system. There’s always something new that will come up along the way and in order for a system to cope up with growing change, then the company must re-engineer its system every now and then. Therefore the cycle starts again.
Information Technology -> The System Development Life Cycle Use/Evaluation Phase Revision Revision Use this question and answer activity to review the phases of the SDLC.
The activity given in the course is very effective to review different phases of SDLC. it is regular process to review systems for improving operational activities. Concerned technical personnel should identify the essential systems .
