BS ISO IEC 33003 pdf download.Information technology — Process assessment — Requirements for process measurement frameworks
1 Scope
This International Standard sets out the requirements for process measurement frameworks for use in process assessment. The requirements defined in this International Standard form a structure which a) establishtherequirementsforprocessmeasurementframeworksinthecontextofprocessassessment, b) establish the requirements for the validation of process measurement frameworks for use in process assessment, and c) establish requirements that are applicable to any process measurement frameworks to develop composite measures across domains. This International Standard is applicable to the development of process measurement frameworks for any process quality characteristic across all application domains. Annex A presents a map of terminologies used in this International Standard. Annex B provides an explanation of construct specifications. Annex C reviews statistical validation methods. Annex D provides some methods including references that can be utilized in implementing the requirements for process measurement frameworks. These Annexes will be moved to a guide for constructing process measurement frameworks to be developed as part of the set of International Standards. NOTE ISO/IEC 33020 is a process measurement framework for assessment of process capability based on this International Standard.
3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO/IEC 33001, ISO/IEC 15939, and the following apply: 3.1 aggregation method method that combines a set of measurement values to create a composite value Note 1 to entry: Aggregation methods are based on compensatory or non-compensatory models.3.2 compensatory model MCDM model in which a composite measure is composed of individually weighted terms and where criteria (also refer to attribute terms) with a high value can compensate for those of a low value in proportion to each weight Note 1 to entry: A compensatory model suggests that improving the more important measures (those with a higher weighting) is more likely to increase or improve the overall composite value than improving the less important ones. This model assumes that the weight (influence level) of criteria remains the same regardless of the measured level of the criteria. 3.3 composite measure variable derived from a set of operations of a construct’s multi-item measures defined according to construct specification (either reflective or formative) that is the way in which the latent variable representing the construct of interest is linked to its measures 3.4 composite value value from a composite measure Note 1 to entry: A composite value can be from an ordinal, interval, or ratio scale. 3.5 construct concept such as the abstract idea, image, underlying theme, or subject matter that one wishes to measure using process assessments Note 1 to entry: In process measurement frameworks, constructs (also refers to latent constructs) are theoretical concepts such as the process quality characteristics and process attributes. Note 2 to entry: The meaning that one assigns to a construct is called theoretical definition, which should explain its meaning, as well as discuss its distinct dimensions (facets). 3.6 dimension distinct components that a multidimensional construct encompasses 3.7 formative construct constructthatisformedfromitsobservedmeasuresintherelationshipbetweenaconstructanditsmeasures Note 1 to entry: The construct is a consequence of its measures and each measure is a determinant of the construct. 3.8 latent variable variable representing a unidimensional construct Note 1 to entry: There should be a separate latent variable for each dimension of a construct and a minimum of one measure per latent variable. 3.9 MCDM Multiple-Criteria Decision Making or Multi-Attribute Decision Making making preference decisions (e.g., evaluation, prioritization, and selection) of available alternatives characterized by multiple criteria Note 1 to entry: A criterion in MCDM corresponds to measure. Note 2 to entry: An MCDM with one alternative is the same as the development of a composite measure.
