What is CMMI and how is it used?

CMMI stands for Capability Maturity Model Integration, which is jointly developed and developed by the U.S. Department of Defense, Carnegie Mellon University and the U.S. Defense Industry Association. It is based on the idea that difficulties in software development can be overcome by concentrating on a sustained effort to establish an effective software engineering process infrastructure, ongoing management practices and process improvements.

CMMI provides a single, integrated framework for improving an organization's processes, and the new integrated model framework eliminates inconsistencies across models, reduces duplication between models, increases transparency and understanding, and establishes an automated, extensible framework. As a result, the quality and efficiency of the organization can be improved overall. The main focus of CMMI is cost-effectiveness, clear focus, process centralization and flexibility.

CMMI is a multidisciplinary, scalable product set that was initially developed to enable integrated process improvement in an organization using two or more single-discipline models. The essence of CMMI is a part of software management engineering. Software process improvement is the core problem of current software management engineering, and the development of computers for more than 50 years has made people realize that in order to develop software with high efficiency, high quality and low cost, it is necessary to improve the software production process.

Model-based process improvement refers to the adoption of a capability model to guide the process improvement of an organization, so that its process capabilities can be improved stably and the organization can become more mature. The success of CMM has led to the development of similar process improvement models in other disciplines, such as systems engineering, requirements engineering, human resources, integrated product development, software procurement, etc., and some improvement models have been derived from CMM, such as: SW CMM, SE-CMM, IPD-CMM, etc.

However, the existence of multiple process improvement models in the same organization can cause conflict and confusion. CMMI is designed to address how to maintain coordination between these patterns.

CMMI is the latest version of the CMM model. Early versions of CMMI (CMMI-SE SW IPPD) were applied to the management of projects in the software industry, and SEI began to be promoted and piloted in some countries and regions. With the popularization of the application and the development of the model itself, the deduction has become a comprehensive model that has been widely used.

Help enterprises establish a quality management system and improve their competitiveness.

CMI (Chartered Management Institute).。Founded in 1945, the Chartered Institute of Management is the only institution in the UK that focuses on management and leadership, and is also the world's authoritative management association. CMI has 520 corporate members, including world-renowned business schools and management research institutions.

Accreditation from CMI indicates that an academic institution is a world leader in management.

CMI (Chartered Management Institute): Computer Management Teaching (CMI) is a variety of applications of computer-supported instructional administration tasks.

CBE, CAI and CMI

CBE (Computer Based Education): Generally speaking, various applications of computers in the field of education are collectively referred to as computer-aided education (CBE).

CAI (Computer Assisted Instruction): Computer Assisted Teaching (CAI) is the technology of using computer technology to assist teaching, which is a further development of program teaching and a new form of program teaching. Its research object is the composition of the human-computer teaching system composed of teachers, students and computers, the relationship between various elements and the law of interaction, with the aim of using computer technology to further optimize the teaching process.

Computer Managed Instruction (CMI): Computer Management Teaching (CMI) is a variety of applications of computer-supported instructional management tasks.

CMI (case-mix index): the number of case combinations, one of the indicators of DRGS group data.

CMI is the English abbreviation of Customer Medicine Information, which is to write easy-to-understand medical information for consumers, that is, to compile CMI, which has become a part of the drug policy of many countries around the world, and its legal basis is that "consumers have the right to decide on their own medical ** or procedures and to know the appropriate information required for the decisions made" as stipulated in the relevant consumer rights bill.

CMMI5: Capability Maturity Model Integration, is a set of multi-disciplinary, scalable product collections, the initial motivation for its development is to use two or more single-discipline models to achieve an organization's integrated process improvement.

1. CMMI is divided into five levels and twenty-five process areas (PA).

2. Evaluation method:

Self-assessment: Used by the company's leadership to evaluate the company's own software capabilities.

Director evaluation: enable the company's leadership to evaluate the company's own software capabilities and announce their own software capabilities.
