2. Manageability level: The basic project management process is established to track the cost, schedule and functional characteristics. The necessary process regulations have been formulated, and the successful experience of similar application projects can be repeated earlier.
3. Defined level: The process of software management and engineering has been documented and standardized, and integrated into the organization's standard software process. All projects use approved and customized standard software processes to develop and maintain software, and the production of software products is visible throughout the software process.
4. Quantitative management level: analyze the detailed measurement data of software process and product quality, and have quantitative understanding and control of software process and product. There is an objective basis for the management to make a conclusion, and the management can predict the performance within a quantitative range.
5. Optimize the management level: quantitative feedback of the process and advanced new ideas and technologies promote the continuous improvement of the process.
Compared with CMMI development model 1.3 (CMMI-Dev 1.3), CMMI development model 1.2 has made the following improvements:
1) renamed the process domain "Organization Innovation and Deployment (OID)" to "Organization Performance Management (OPM)", and added a new specific goal and several new concrete practices.
2) The model architecture is improved and the use of multiple models is simplified.
