Utilizing a capability maturity model is the best way for a CIO to assess the consistency of IT processes against industry benchmarks and determine where to focus improvement initiatives. Capability maturity models provide a structured framework for evaluating the maturity of an organization's processes in comparison to industry best practices. This approach helps identify areas of strength and opportunities for improvement, guiding strategic decisions on where to allocate resources for process enhancements. While balanced scorecards, key performance measures, and IT process audit results are useful, a capability maturity model offers a comprehensive assessment specifically designed for process improvement.
