How to Select an Appropriate CMMI Model

A CMMI model is a simplified representation of specific organizational process that must be investigated in order to understand the overall capabilities of that organization.  Finding or determining models of CMMI will allow companies to appraise a supplier or a service provider.  The CMMI model therefore is essentially a stakeholder’s tool to correctly assess the organizational levels and strengths of a third party company.

There are different kinds of CMMI models that can be used.  These are generally available on a CMMI website that offers trademarked CMMI products.  There are CMMI models for Systems Engineering, Software Development and General Engineering, Process Development, and Integrated Supplier Sourcing.

There are two important factors that must be considered when selecting a CMMI model.  These are called representation factors. It is imperative for organizations to carefully select what CMMI model representation will suit their corporate norms and standards.

The first CMMI model representation is the staged version.  It can provide a sequential systems view of organizational processes. This could mean enhanced understanding of the maturity and capabilities of involved organizations.  With a sequential method of analyzing the process, companies can determine where to implement improvements along the entire organizational process.

The second model representation is the continuous version.  It allows companies to select the best and most suitable methodologies of improving an organization’s process.  Because continuous representation provides appraisers with an organized set of standards, they can determine which organization will fit in their set categories so that improvement methods can be easily integrated into the process.
