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

The SyMed development team called in the architect of the system and a step back to the analysis phase was made. Their entire development team, along with the architect, made a trip from Nashville to Louisville to redo the initial analysis. The team went back to Nashville with the new data and called back to say they could not do the project. The end of the project consumed uncounted person-hours, 7 months on the calendar and about $25,000 dollars.
The next part of the implementation phase is installation. This phase is accomplished by several methods. The first is direct installation. This is where the new system is installed and implemented and the old system is “turned off.” This is a simple but risky way for a new system to be deployed. The next possible method of installation is parallel. This method is demonstrated by keeping both systems going for an extended amount of time. This is a low risk but high cost implementation scenario. Phased installation is the last method and is characterized by multiple possible pathways to final installation. Phased installation is also low risk, but can become quite complex due to the multiple pathways (Satzinger et al., 2004). The TPI credentialing system, had it made it to this phase, was to be a parallel installation.
Documentation is the next phase of implementation and usually consists of user documentation
