A Practical Application of the IDEAL Model

The focus of this research is to outline the experience of a small-to-medium-sized European-based software development organization, utilizing the IDEALSM model while implementing a tailored Capability Maturity Model® (CMM®) software process improvement (SPI) program.[CMM is registered in the US Patent and Trademark Office by Carnegie Mellon University.] The goal of the approach undertaken was to achieve process improvement rather than a specific CMM® maturity level. In doing this, the IDEALSM model was extensively researched and employed. The benefits and limitations of the use of the IDEALSM model are presented as experienced. Research was carried out on a number of software process improvement paradigms prior to the final selection of the CMM®. The approach employed as far as possible remained true to the spirit of the CMM®. A key element of this strategy was to see the requirements of the organization as paramount and immediate. It was deemed important for the organization to achieve specific Key Process Areas regardless of their position in the CMM®. The approach provided the organization with the flexibility to invest in the achievement of specific maturity levels at some future date and thereby capitalize on their current process improvement work.
