According to Wikipedia1, a maturity model is a framework for measuring an organization’s maturity, or that of a business function within an organization, with maturity being defined as a measurement of the ability of an organization for continuous improvement in a particular discipline. A maturity model will best indicate the effectiveness and efficiency of an organization or a business function, as it helps to evaluate how well they achieve their intended objectives with minimum resources, time, and cost. A maturity model also helps to identify and prioritize the areas and opportunities for improvement, and to establish and communicate the standards and best practices for the discipline. References = Wikipedia1
