Comparative Analysis of CMM and cmme process Domains

Level	CMMProcess domain	CmmeProcess domain	Description and Comparison
2	Demand management Software Project Planning Software project tracking and monitoring Software Sub-Contract Management Software Quality Assurance Software Configuration Management	Demand management Project Plan Project Supervision and Control Supplier Contract Management Process and product quality management Configuration Management Measurement and Analysis	The basic content of project process management is the process capability of one or more teams in the organization. It can be said that it is the content of TSP. The difference at this level is that a process field "Measurement and Analysis" is added to the CMMs ".
3	Key Points of software process Software Process Definition Training Plan Software Integration Management Software product engineering Inter-group collaboration Peer review	Organization-level process focus Organization-level process definition Organization-level training Integrated Group Integrated Project Management Organization-level integration environment Demand Development Technical solutions Product integration Verify Confirm Risk Management Decision Analysis and Solutions	Starting from Team process capability to organizational process capability, there are many process domains in the relevant organizations, such as organization-level process definition and focus, organization-level training and integration environment, product integration, and integrated project management. It also includes some in-depth project management capabilities, such as requirement development, risk management, and decision analysis. "Software Integration Management" in CMM is divided into three process domains: integrated group, integrated project management, and integrated organization-level environment. "Software product engineering" in CMM is divided into four process domains: requirement development, technical solutions, product integration, verification, and validation. The collaboration between CMM groups is included in the integrated project management of CMMS, while the same level evaluation of CMM is included in the verification of CMMs.
4	Process quantification management Quality Management	Quantitative Project Management Organizational Process Performance	Organizational process performance is based on quantitative management, and both constitute a complete quantitative management. The "Quality Management" in CMM has been moved to level 2 of cmme, which has undergone major changes.
5	Error Prevention Technical Change Management Process Change Management	Causal Analysis and Solutions Organization-level reform and implementation	Causal Analysis is a tactical improvement by analyzing methods and technical problems in the process and finding out the root cause to solve the problem; "organizational reform and implementation" is a strategic improvement. Organizational changes are first of all changes in management culture, quality policies, and training systems. In CMM, it focuses on continuous improvement in both technology and process. "Defect Prevention" is a basic content in quality assurance or management and should not be placed at level 5th. Therefore, cmme has been corrected.
