CMMM Intelligent Manufacturing Maturity Model

Authoritative guide for digital transformation of manufacturing industry

Official definition: CMMM is the China Manufacturing Maturity Model (CMMM), a national standard jointly developed by the China Electronics Standardization Institute (CESI) and the Ministry of Industry and Information Technology (MIIT) (GB/T 39116-2020).

Core objective:

Addressing the core pain point: Resolving the common dilemma of "unclear direction, unclear path, and unpredictable effects" in the intelligent transformation of enterprises.
Building a unified language: Establishing a unified standard for evaluating intelligent manufacturing capabilities across industries and regions, promoting industry chain collaboration.
Supporting national strategy: providing objective basis for the government to implement precise policies (such as selecting demonstration factories and allocating special funds), and promoting the optimization of industrial resource allocation.
Benchmarking international frontiers: Achieving compatibility with international standards (such as IEC 62264, RAMI 4.0) and helping Chinese enterprises integrate into the global intelligent manufacturing system.

Strategic Value: CMMM is a key infrastructure for implementing the national manufacturing power strategy, providing enterprises with a scientific and systematic intelligent manufacturing capability evaluation method, helping them accurately position their development level, optimize resource allocation, and achieve intelligent upgrading. This provides essential evaluation criteria for enterprises to benchmark against international advanced levels and participate in national level intelligent manufacturing projects

The Capability Maturity Model for Intelligent Manufacturing (CMMM) is a systematic methodology aimed at helping businesses assess the current status of their intelligent manufacturing capabilities and provide clear paths for improvement. The core framework of CMMM consists of the following key components:
1. Five maturity levels
CMMM divides the level of enterprise intelligent manufacturing from low to high into five levels, each corresponding to different capability characteristics and requirements:

2. Four ability elements

CMMM focuses on four core competency elements to ensure that enterprises consider the coordinated development of various links in the industrial chain when promoting intelligent manufacturing:

Personnel: including two competency domains of organizational strategy and personnel skills, emphasizing the need for enterprises to develop clear intelligent manufacturing strategies and possess corresponding personnel skills.
Technology: covering three domains of data, integration, and information security, requiring enterprises to have corresponding capabilities in data collection, system integration, and information security.
Resources: including two capability domains: equipment and network, focusing on the intelligence level of key equipment and the construction of network infrastructure in enterprises.
Manufacturing: involves five capability domains of design, production, logistics, sales, and service, requiring enterprises to achieve intelligence in product design, production process, logistics management, sales and service, and other aspects.


3. Twenty ability subdomains

In order to more finely characterize the various capability requirements of enterprises in intelligent manufacturing, CMMM is further subdivided into twenty capability subdomains.
These subdomains cover multiple levels such as resource elements, interconnectivity, system integration, data analysis, information security, and organizational culture, collectively forming a complete capability system for intelligent manufacturing.
For example:
Data subdomain: Enterprises are required to adopt sensing technology to achieve automatic collection of key link data and establish unified data encoding and exchange rules.
Integration subdomain: Enterprises are required to form a complete system integration architecture to achieve integration between equipment, control systems, and software systems.
Design subdomain: Emphasize the digitization and intelligence of product design, such as using computer-aided design (CAD), simulation technology, etc.

（I.） The application value of CMMM
1. Balanced development of all-round capabilities
CMMM not only focuses on the manufacturing process of product realization (such as design, production, logistics, sales, and service), but also covers organizational, resource, and technical aspects. Its 20 capability subdomains have put forward construction requirements for intelligent control of various business operations of enterprises, emphasizing the balanced development of multi-faceted capabilities of enterprises.
By avoiding the "barrel effect" caused by single point capability enhancement, CMMM can help enterprises achieve long-term stable development.

2. Policy support and resource acquisition
CMMM certification has been included as a core indicator in multiple national and local policies, such as the "National Intelligent Manufacturing Pilot Demonstration Project" and the "High Quality Development of Manufacturing Industry Special Project". Enterprises certified by CMMM are given priority in obtaining financial subsidies, tax incentives, project application qualifications, etc., such as up to 30% of the project investment for intelligent manufacturing transformation special funds.

3. Enhance market competitiveness
By quantifying indicators, enterprises can achieve precise management, reduce operating costs, and improve production efficiency. For example, after obtaining CMMM L4 certification, a household appliance company reduced equipment downtime by 45% and operation and maintenance costs by 28%.
CMMM also helps companies build predictive maintenance models, optimize supply chain management, improve inventory turnover and R&D cycles.

4. Assist in digital transformation
CMMM provides enterprises with a clear path for intelligent development, avoiding blind investment and the problem of technology "unfinished buildings". Its hierarchical capability model (L1-L5) provides enterprises with a complete roadmap of "diagnosis planning implementation".
By promoting collaboration among various departments within the enterprise, breaking down information silos, and achieving data sharing and business integration.

5. Intelligent manufacturing talent cultivation
CMMM provides a solution for manufacturing enterprises to cultivate "pillar like" talents. At present, more than 4000 students from 1200 manufacturing enterprises across the country are systematically learning the application methods of CMMM, covering more than 30 industries such as equipment manufacturing and electronic information.

（II.） Applicable scenarios of CMMM
1. Internal applications within the enterprise
Self evaluation and diagnosis: Enterprises can conduct self diagnosis through the intelligent manufacturing evaluation public service platform to identify their own shortcomings in intelligent manufacturing capabilities.
Develop strategic planning: CMMM provides enterprises with a gradual upgrade path from automation and standardization foundations to business model innovation, helping them anchor business goals and efficiently implement intelligent construction.
Optimizing production processes: With the guidance of CMMM, enterprises can optimize their production processes, improve production efficiency and product quality.

2. Application of suppliers and investors
Suppliers: Through CMMM, suppliers can better grasp the needs of Party A, clarify the technical implementation path, and optimize solutions.
Investor: The investor can evaluate the intelligent manufacturing level of the enterprise through CMMM, identify excellent enterprises, and grasp the development trend of intelligent manufacturing.

3. Industry and regional applications
Industry application: CMMM is suitable for manufacturing enterprises of different production organization modes, industries, and scales.
For example, typical scenarios such as discrete process digital design, self-organizing flexible production, and agile supply chain can be evaluated and optimized through CMMM.
Regional application: Local governments promote the development of intelligent manufacturing for regional enterprises by adopting CMMM standards. For example, provinces and cities such as Jiangsu, Shandong, and Guangdong encourage enterprises to apply CMMM through technological transformation subsidies, corresponding level subsidies, and other means.

4. Construction of intelligent manufacturing engineering
CMMM has proposed construction requirements based on three levels: intelligent workshop, intelligent factory, and intelligent supply chain, to help enterprises achieve different business goals and objectives.
Through CMMM, enterprises can avoid the "pilot trap", avoid detours, and accurately implement intelligent manufacturing projects
