Capability Maturity Models (CMMs)

Capability Maturity Models (CMMs)

The Capability Maturity Model (CMM) was developed by Carnegie Mellon University. CMM states that it “is specifically developed to support an organization’s need to assess and improve their systems engineering capability”. It can easily coexist with any business process and has defined 5 levels of maturity:

  • level 1– Initial – process is unpredictable, poorly controlled and reactive;
  • level 2– Managed – process is characterized but is often reactive;
  • level 3– Defined – process is defined, repeatable and proactive;
  • level 4– Quantitatively Managed – process is measured and controlled;
  • level 5– Optimized – focus on process improvement.

There are a number of CMM models that can be used for different processes within your organization, these include but are not limited to:

  • BCMM– Business Continuity Maturity Model;
  • BSIMM– Building Security In Maturity Model;
  • CMMI– Capability Maturity Model Integration – there are various models for Services, Development etc – can be used for any part of the business;
  • H&SMM– Health and Safety Maturity Model;
  • IQMM– International Quality Maturity Model (Dipsticks);
  • ISM3– Information Security Management Maturity Model;
  • ITSMMM– IT Service Management Maturity Model;
  • OSIMM– Open Group Service Integration Maturity Model;
  • P3M3– Portfolio, Programme and Project Management Maturity Model;
  • P-CMM– People – Capability Maturity Model
  • SSE-CMM– Systems Security Engineering – Capability Maturity Model;

Six Sigma

Six Sigma is a process originally developed by Motorola to systematically improve processes by eliminating defects. It uses statistical processes to measure a process in terms of defects and allows your organization to define its vision in numerical terms. There are a number of tools and techniques used to support the process. Defects are then isolated and eliminated thereby reducing the overall costs and costs of rework during production and post production maintenance.

It uses the DMAIC process:

  • Define;
  • Measure;
  • Analyze;
  • Improve
  • Control
