The paper evaluates how hospital information systems are designed and implemented to gain the greatest insights and needs analysis from stakeholders before the programming and development work begins. The paper looks at how the System Development Lifecycle (SDLC) works to capture insights and explores the role of Six Sigma as part of SDLC strategies as well as the use of a wide variety of Unified Modeling Language (UML) based tools. The paper shows how the development of medical systems based on stakeholder needs is going through a revolutionary time today, with the SDLC and Six Sigma frameworks bringing greater accuracy, accountability and measurement of results to this area of system development.

Capturing Insights as part of the Software Development Lifecycle (SDLC)
Modeling Processes with UML based on Business Process Re-Engineering

From the Paper:

"The SDLC is comprised of six components, with each designed to further provide greater clarification and communication of user's requirements as they are translated into software features. The SDLC is considered the most reliable platform for capturing stakeholder needs as this framework has specific steps dedicated entirely to capturing, interpreting, verifying and developing software to user needs (Bendraou, Jezequel, Gervais, Blanc, 2010). The parallels to the Six Sigma methodologies increasingly being used to measure how well an SDLC initiative fit the needs of a hospital information system are also redefining how process improvements are completed (Grant, Mergen, 2009). These parallel developments of the SDLC and Six Sigma are what bring stakeholder requirements into each phase of this development model (Pocha, 2010). Initial development initiatives and programs of medical systems showed that stakeholders could be provided a scorecard that gave them metrics and key performance indicators of process performance gains over time (Dodd, Carr, 1994).
"The capturing of stakeholder requirements during the System Engineering and Modeling phase, and further redefined during the Software Requirement Analysis and feasibility studies are today measured by Six Sigma methodologies to ensure stakeholder requirements are being met (Bendraou, Jezequel, Gervais, Blanc, 2010). The Six Sigma process however requires that there be a series of iterative review of design requirements, evaluation of the variation in planned versus actual performance, and the development of a specification to drive Systems Analysis and Review (Russell, Yilmaz, 2006)."
