Purpose of the Process Reference Model

B.

The Process Reference Model (PRM) is a key component of the COBIT (Control Objectives for Information and Related Technology) framework, which is a business framework for the governance and management of enterprise IT. The PRM defines a set of generic IT processes that can be used to manage and govern IT in an organization.

The main purposes of the PRM are to provide a common language and framework for IT process management, to establish a basis for process capability assessment, and to support the development of Process Assessment Models (PAMs).

Option A states that the PRM forms the basis of a process capability assessment for the Capability Dimension. This is a correct statement, as the PRM is used to assess an organization's process capability and maturity level in the Capability Dimension of COBIT.

Option B states that the PRM provides the mechanism whereby defined PAMs are related to the measurement framework. This is also a correct statement, as the PRM provides the basis for the development of PAMs, which are used to assess an organization's process capability and maturity level in a specific process area. PAMs are related to the measurement framework through the use of maturity models and capability levels.

Option C states that the PRM provides the basis for one or more PAMs. This is also a correct statement, as the PRM serves as a foundation for the development of PAMs.

Option D states that the PRM provides the basis to undertake an assessment on the process dimension. This statement is not correct, as the PRM is used to assess an organization's process capability and maturity level in the Capability Dimension of COBIT, not the process dimension.

Therefore, the answer is option D: "Provides the basis to undertake an assessment on the process dimension" is not a purpose of the Process Reference Model.
