CMMI best practices are published in documents called models, each of which addresses a different area of interest. The fix would include updating the process documentation and training involved where the errors were injected. CMMI Process Areas: Capability Maturity Model Integration (CMMI) is based on a rock-solid framework designed to improve the processes originated from the Software Engineering Institute for Software Development along with its relevant Acquisition. By January 2013, the entire CMMI product suite was transferred from the SEI to the CMMI Institute, a newly created organization at Carnegie Mellon. In CMMI models with a contiunous representation, there are six capability levels designated by the numbers 0 through 5. This approach promotes that members of the EPG and PATs be trained in the CMMI, that an informal SCAMPI C appraisal be performed, and that process areas be prioritized for improvement. Capability Level 5 focuses on studying performance results across the organization or entire enterprise, finding common causes of problems in how the work is done (the process[es] used), and fixing the problems in the process. Risk Management Quantitative Project Management, Measurement and Analysis Causal Analysis and Resolution, Organizational Environment for Integration (IPPD). The process areas below and their maturity levels are listed for the CMMI for services model: Maturity Level 4 – Quantitatively Managed. In the staged representation, process areas are organized by maturity levels. David J. Anderson 2005 gives hints on how to interpret CMMI in an agile manner. Characteristics of the CMMI Model. The Standard CMMI Appraisal Method for Process Improvement (SCAMPI) includes three methods: Class A, Class B and Class C. SCAMPI Class A appraisals are conducted after an organization has implemented changes and process improvements and feels that it’s time to determine a new benchmark using the CMMI framework. The staged representation is designed to provide a standard sequence of improvements, and can serve as a basis for comparing the maturity of different projects and organizations. Each level is a layer in the foundation for continuous process improvement. Capability Maturity Model Integration CMMI is a process level improvement training and appraisal program. Trying to keep up with the industry the model also has explicit reference to agile aspects in some process areas. All Rights Reserved. According to the Software Engineering Institute SEI, 2008, CMMI helps "integrate traditionally separate organizational functions, set process improvement goals and priorities, provide guidance for quality processes, and provide a point of reference for appraising current processes.". CMMI Maturity Levels. CMMI defines three Constellations – Development, Acquisition and Services – that function as the core of business. SCAMPI Class C appraisals are designed to be quick and flexible — more so than Class A or B. The CMMI model breaks down organizational maturity into five levels. Depending on the areas of interest acquisition, services, development used, the process areas it contains will vary. In version 2.0 the above representation separation was cancelled and there is now only one cohesive model. Version 1.3 provides models for three areas of interest: development, acquisition, and services. This translated into tangible benefits for the customer including low project risk, on time on budget deliveries, minimal defect rate, high process visibility and enhanced customer satisfaction.
SCAMPI also supports the conduct of ISO/IEC 15504, also known as SPICE Software Process Improvement and Capability Determination, assessments etc. Both the defined processes and the organization's set of standard processes are targets of improvement activities.

Administered by the CMMI Institute, a subsidiary of ISACA, it was developed at Carnegie Mellon University CMU. You’ll naturally progress to higher levels through trial and error, as they will help inform improvements.
They suggest one should combine the different fragments of the methods into a new hybrid method. Some major changes in CMMI V1.3 are the support of agile software development, improvements to high maturity practices and alignment of the representation staged and continuous. All businesses start at the initial stage when creating a new development process. A new product called Accelerated Improvement Method AIM combines the use of CMMI and the TSP. CMMI Maturity Levels.
More modern approaches, that involve the deployment of commercially available, CMMI-compliant processes, can significantly reduce the time to achieve compliance. CMMI is the successor of the capability maturity model CMM or Software CMM. Process areas are the areas that will be covered by the organization's processes.
