4 Requirements for process measurement frameworks This clause defines the requirements for developing process measurement frameworks. Guidance in this International Standard is limited to providing a better understanding of these requirements. Figure A.1 provides a mapping of the relationships between some terms used in this Clause. NOTE Guidance on achieving conformance to these requirements, including examples and methods, will be provided in a guide for constructing process measurement frameworks to be developed as part of the set of Standards. 4.1 Conceptualization 4.1.1 Requirements a) A measurement framework shall identify and address a single process quality characteristic; b) A process quality characteristic in a process measurement framework shall be defined on the basis of a multidimensional construct; c) A process quality characteristic in a process measurement framework shall be defined as a set of process attributes; d) Each process attribute shall define a property of the process quality characteristic; e) Each process attribute that is not directly measurable shall be considered as a construct; f) Process attributes in a process measurement framework shall be defined as either reflective or formative. g) The measurement framework shall document the policies and assumptions underlying its use and application; 4.1.2 Guidance The process of identifying and clarifying concepts is called conceptualization. A concept is an idea or image that unites phenomena of interest (e.g., traits, behaviour traits) under a single term. It is a summarizing device to replace a list of specific traits. Most process quality characteristics (e.g., process capability) are not observable but are theoretical concepts called constructs. The composite measures (e.g., process capability level) used in process measurement frameworks are defined on the basis of a construct composed of process attributes. A measurement framework may be structured into a series of levels of achievement.
