Capability Maturity Model

This example Southbeach Notation model shows what qualities characterise an organisation at each of the different maturity levels defined by the Carnegie Mellon Capability Maturity Model.

The maturity levels are shown here as Southbeach goals (filled in boxes). Note that levels 0 and 1 are considered harmful (red), whilst levels 2 through 5 are considered increasingly useful. The useful (green) and harmful (red) qualities of the organisation are shown for each level.

Note how increasing levels of maturity characterise increased understanding, documentation, and management of the processes. The activities involved in executing those processes, and in moving towards higher quality, more efficient and autonomous processes are managed through repeatable, objective, statistical means rather than through dependency on heroic behaviour, individual knowledge and personal judgement.

Models like this can be used to assess the maturity of an organisation. More specific versions of this model can be created as issues impacting quality and performance are identified. The ability in Southbeach to indicate the cause and effect of situations can then be used to perform root cause analysis to identify ways of improving the processes and maturity of the organisation in manageing those processes. Having clearly articulated improvement milestones enables remediation planning to be directed in a more coherent and effective way.

Models and appraisal methods for services, acquisition and development processes are available from the SEI website:
