Two types of organizations are likely to adopt CMMI: those who have already used process-improvement models and those that are new to process improvement. Many organizations have been using the SW-CMM
or the SECM, so these organizations are
Organizations with Experience
Organizations that have used the SW-CMM or the SECM will have an easier time adopting CMMI than organizations that haven't because these two older models share many similarities with CMMI. Also, a significant portion of the practices found in each model also appears in CMMI.
As demonstrated in chapter 7, organizations, such as United Space Alliance, that have experience with an older model can adopt CMMI in a way that
Of course, this strategy can be used by any organization using any process-improvement model. Compare your current efforts and achievements to CMMI. Most likely, you'll find that you are already implementing many of the best practices in CMMI and you'll see the value in the best practices you have yet to implement.
The Capability Maturity Model for Software
CMMI incorporates the version 2.0 draft C improvements to the Capability Maturity Model for Software [SEI 97b], or SW-CMM version 1.1, as well as other improvement information
The Software CMM practices at maturity levels 4 and 5 have been improved based on experience gained since the publication of the SW-CMM version 2.0 draft C. These practices have been further refined based on studies
Organizations that have achieved maturity level 4 or 5 may wish to make the transition more quickly to take advantage of the additional organizational coverage described in the CMMI models. Organizations that have begun significant efforts toward a maturity-level 2, 3, or 4 rating must
For example, a company with several months remaining before a maturity level 4 appraisal might want to charter small
Electronic Industries Alliance's Systems Engineering Capability Model
CMMI incorporates many of the practices from the Electronic Industries Alliance's (EIA's) Systems Engineering Capability Model, or SECM [EIA 98]. In fact, CMMI Engineering process areas are built
The most noticeable difference between CMMI and the SECM is that CMMI provides a great
Organizations that have achieved high capability levels using the SECM may wish to make the transition to CMMI quickly to take advantage of the additional informative material and organizational coverage described in CMMI models. Organizations that have begun significant effort toward achieving a target profile that contains lower capability levels must carefully determine the best timing for the transition to CMMI. A possible approach to easing into CMMI adoption is to augment current plans with selected process areas that would be of the greatest business value.
For example, a company with several months remaining before an appraisal might want to charter small teams to investigate process areas
Organizations New to Process Improvement
Organizations without process improvement experience can, in general, approach the adoption of CMMI as they would approach the adoption of any process-improvement model. The advantage to beginning their improvement efforts using CMMI is that expansion of the process improvement program to include multiple disciplines, groups, and organizations is easier and more straightforward than with any other process-improvement model.
Once your organization has decided to adopt CMMI, planning can begin with an improvement approach such as the IDEAL SM (Initiating, Diagnosing, Establishing, Acting, Learning) model [SEI 2]. For more information about the IDEAL model, see the Software Engineering Institute Web site at the following URL: http://www.sei.cmu.edu/ideal/ideal.html.
Research has shown that the most powerful initial step to process improvement is to build strong organizational sponsorship before investing in process
For an organization with a mission to develop software-
CMMI Model Training
Whether your organization is new to process improvement or is already familiar with process-improvement models, training is a key element in the ability of organizations to adopt CMMI. An initial set of courses is provided by the SEI and its transition
The SEI and its transition partners offer the Introduction to CMMI course, which provides a basic overview of the CMMI models. The SEI also offers the Intermediate Concepts of CMMI course to those who plan to become more deeply involved in CMMI adoption or appraisal -for example, those who will guide improvement as part of a process group, those who will lead SCAMPI appraisals, and those who will teach the Introduction to CMMI course. Current information about CMMI training is available on the Software Engineering Institute Web site at the following URL: http://www.sei.cmu.edu/cmmi/training/training.html.
