Credentialing System Implementation at xxx Health Systems The previous two parts of this three-part assignment, the systems analysis and application architecture and process design aspect of the credentialing software project at TPI Health Systems (TPI) was explored. This last paper will explore the implementation stage of the systems development life cycle (SDLC) as it related to the credentialing project at TPI. There are six major steps to the implementation phase of the SDLC: (1) coding, (2) testing, (3) installation, (4) documentation, (5) training and (6) support. The text actually details five steps and breaks-out the last step, support, into its own phase (Satzinger, Jackson, & Burd, 2004, p. 626). The first phase, coding, is …show more content…

These changes did not fit into the SyMed project plan, so the TPI process was changed to accommodate the pre-written user interface of the SyMed system. Testing is the next phase of the implementation phase. A comprehensive testing program includes a stepwise process starting with unit testing, followed by testing of group components called integration testing and concluded with entire systems test (Satzinger et al., 2004, p. 640). Individual units or modules are tested prior to integration with more advanced modules, using driver modules. Once a set of modules are put together, integration testing can take place. These test include checking for interface compatibility, run-time exceptions, parameter values and unexpected state interactions (Satzinger et al., p. 644-645). Jeff Theobald suggests that an effort should be made to concentrate not on just errors in a single application or module, but also the system as a whole and between systems (Theobald, 2007). After these tests are completed, the project goes on to system testing. System testing often involves daily “build and smoke” tests, where the system is set to run and is observed for “smoke” or errors (McConnell, 1996). The TPI credentialing system was tested in this manner. The project made it through the first two testing
