Abstract:

The current System Development Life Cycle (SDLC) is used for large system and software development projects. SDLC is a methodology that describes the stages of analysis in a project from initiation to completion. However, with 21st century problems increasing, the boundaries have been reached and an improved approach is needed. This research addresses the complexities of the development of a Modified System Development Life Cycle (MSDLC). This modification extends the capabilities of the SDLC. The MSDCL includes Joint Application Development (JAD) sessions, continuous user involvement, and intermediate documentation of analysis to expand the SDLC capabilities. Major additions are incorporated into the cost saving system analysis phase. To expand on the cost savings found in the system analysis phase, a three-phase modeling and analysis process has been defined: Object-Oriented, Z language, and Alloy to provide a more complete analysis and validation procedure to improve problem solutions.
