The team is reflected in the CMM (this paper reproduces the Software Engineering Expert Network www.21cmm.com) CMM combines management methods and technical means, emphasizing team spirit, emphasizing the mutual constraints of collaboration after division of labor. Behind the team's spirit relies on the power of collectives: jointly take responsibility and sharing danger. In CMM implementation, a corporate culture is also created - team spirit. 1. The trade of importance companies in collaborative role is generally consisting of four elements, integration, resource allocation, competitive advantage, and collaboration, where business scope refers to the field of business activities; resource allocation refers to enterprises in the past and The level and model of current resources and skill configurations; competitive advantage refers to competitive status different from competitors' different competition in the market; while collaborative cooperation refers to the results of the company to achieve the sum of the simple sums of simplicity. CMM attaches great importance to the power of collective, using resources for public software, sharing information, sharing hardware and other resources, enabling the company to implement CMM, can enjoy the synergy greater than the sum of the power, relying on the quality of the collective to improve the quality of development, common Sharing the risk of development failure. 2. CMM attaches great importance to the development capabilities and development potential of the company Perhaps a company can produce a good performance in a unregulated open and civilian way, but this product is very fragile, once the external environment is slightly changed Or happen to flow, organizations will not work properly. The CMM model is transparent. It will break the complex system into independent modules. Each member knows its work range, work standards, and the development goals of work, each member plays him within the specified range. Creativity and make your own contribution to the success of the company, and the company is full of vitality. CMM emphasizes sharing risks and responsibilities under the overall goal. The standardization work makes the development of the software are no longer so mysterious, but relies on the team spirit to evaluate the model, and the road is working on the road to standardization and overall development. 3. Demand definitions Pay attention to team spirit The requirements management in the event standards for demand management are responsible for the system engineering group. The system engineering group is composed of managers and technicians, and they need to determine the demand in the hardware software environment and input and output requirements, establish documents, and responsible for the quality definitions. Before the system is formally implemented, the demand definition must also be reviewed and modified by software engineering groups, and they work together to ensure that demand definitions have high quality. 4. The test work relies on the team's power software quality assurance group and experts regularly review the quality of the test quality. The software quality assurance group is not tested in a time. In the initial stage of project development, the team will participate in the development process of the planning standard, which is conducive to future verification. The team's test work is not a one-time short-term behavior, but should be periodically for review every time a period of time. The person in charge of the group should report to the software engineering group, senior management personnel and managers should also participate regularly. Review activities. In addition, the work of the software quality assurance group should also be supervised by experts independent of the group. In summary, on the road to sustainable development in the software industry, CMM will have an important role in the overall capacity and team spirit, and will have a positive and profound impact.
