Using a Project Management Maturity Model (PMMM) to maintain competitive advantage

Competitive Advantage

Competitive advantage is the set of factors or capabilities that allows companies to consistently outperform their rivals whilst enjoying sustained levels of high performance.

However, for many organisations, survival and prosperity are also linked to their ability to effectively compete in an increasingly global market.

Doldrum Bay Consulting believe that by improving a company's overall maturity in the field of project management (especially around delivering change through technology), companies can positively influence their competitive advantage and better compete in a global market.

Project Management Maturity Model

There are many project management maturity models available. The majority are based on the Software Engineering Institute’s “Capability Maturity Model” (CMM) [Carnegie Mellon Software Engineering Institute, 1993].

The model chosen by Doldrum Bay Consulting came from Harold Kerzner who has written several books on the subject [Kerzner, 2001, Kerzner, 2003].

In his book, “Strategic Planning for Project Management Using a Project Management Maturity Model”, Kerzner developed a model for measuring the maturity of an organisations project management processes and procedures, along with the ways of improving that maturity [Kerzner, 2001]. The model is shown below.

Project Management Maturity Model

The Kerzner Project Management Maturity model is like the CMM in that both define five levels of maturity, with the theory that the higher the level of maturity, the better the overall project management performance.

The movement between the different levels is not necessarily a sequential process. Some of the levels can overlap. However, each must be completed in the order given. For example, level 1 (common language) and 2 (common processes) can overlap, but level 2 cannot be completed before level 1 is complete [Kerzner, 2001: 43].
