Maturity Model

The ILM2.0 maturity model fulfills two purposes:
  1. It defines a common framework and language for discussing ILM maturity. Then it enables a relative comparison for how far along an organization is in terms of implementing good ILM practices. This allows an organization to see how they compare to best practices and to other organizations.
  2. It provides information to organizations about ILM best practices that allows them to improve their ILM implementations. In some cases it may provide a basis for an organization to start an ILM implementation. This allows organizations to provide storage service levels appropriate to the value of their information. Often this will reduce costs as organizations start to feel comfortable with providing lower cost service levels for lower value data. 
BENEFITS OF SERVICE-LEVEL AUDITS USING A MATURITY MODEL APPROACH:

Capability Maturity Models (CMMs) address this problem by providing an effective and proven method for an organization to gradually gain control over and improve its IT-related development processes. Such models provide the following benefits:
  • They describe the practices that any organization must perform in order to improve its processes.
  • They provide a yardstick against which to periodically measure improvement.
  • They constitute a proven framework within which to manage the improvement efforts.
  • The various practices are typically organized into five levels, each level representing an increased ability to control and manage the development environment.
An evaluation of the organization's practices against the model determines the level at which the organization currently stands. It indicates the organization's maturity in the area concerned, and the practices on which the organization needs to focus in order to see the greatest improvement and the highest return on investment.

EXAMPLE MATURITY MODELS:

Maturity models provide a means for seeing “what are we getting into?” The higher levels of maturity present a vision or future state toward which state govern- ment aspires and corresponds to not only a mature data governance discipline, but also describe a mature enterprise architecture discipline.   Source: NASCIO, "Maturity Models – A Path to Progress"




The ILM2.0 community uses the maturity model as a 
key tool in a service-level audit.
