- 12 - a system can operate together, and (iii) acceptance testing is performed to determine whether the business user's requirements have been satisfied. Further, during this phase, the programmers correct errors in the coding process (known as debugging) as well as in the design process. Typically, the testing known as regression testing is performed on prerecorded data. The use of prerecorded data is important because the testers have known solutions and outcomes against which the software can be tested, and new methods, capabilities, and functions can be tested without risk to real (production) data. H. Phase 8: Implementation In the implementation phase, the software is placed into production (also known as going live), usually in a gradual process. During this phase, the software application is used on actual data by the end users (those who will be using the software product). It is also during this phase that the end users are trained in the use of the software. I. Phase 9: Postimplementation In the postimplementation phase, the software is maintained through continuous debugging, updating, and enhancing to meet new business needs.Page: Previous 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 Next
