BS ISO IEC 33004:2015 pdf free download – Information technology – Process assessment – Requirements for processreference, process assessment and maturitymodels
A process outcome describes one of the following:
-production of an artifact;
-a significant change of state;
-meeting of specified constraints, e.g.requirements, goals etc.
NOTE1 Achievement of the process outcomes,without any management or control factors related to theselected process quality characteristic, demonstrates basic satisfaction of the process purpose; this level ofachievement is typically recognized as satisfying an important process attribute in any process measurementframework. Where the process measurement framework is structured as an ordinal scale, this process attributeconstitutes process quality level 1.
NOTE2 For detailed guidance on the content and definition of process descriptions, refer to ISO/IEC 24774[3.An increasing number of international, nationalandindustry standards describe process models.These models aredeveloped for a range of purposes including process implementation and assessment.The terms and descriptionsused in such models vary in format, content andlevel of prescription.ISO/IEC/TR24774 presentsguidelines fortheelements used most frequently in describing a process: the title, purpose statement, outcomes, activities and tasks.The primary purpose of lSo/IEC/TR 24774 is to encourage encourage uniformity in the description of processes,and following these guidelines allows the combination of processes from different process reference models.
NOTE3 As defined in ISO/IEC/TR 24774, an outcome is an observable result of the successful achievement ofthe process purpose, and thus it is assessable.
5.5 Verifying conformity of process reference models
Since a process reference model may be developed by a community of interest,or a relevant Internationalor National Standard, or Publicly Available Specification, verification of the extent to which a processreference model meets the requirements of this International Standard may be through eitherdemonstration of conformity or demonstration of compliance. The party performing verification ofconformity shall obtain objective evidence that the process reference model fulfils the requirements setforth in 5.3.Objective evidence of conformance shail be retained.
NOTE Conformity is fulfillment by a product, process or service of specified requirements.Compliance isadherence to those requirements contained in International Standards and Technical Specifications whichspecify requirements to be fulfilled by other International Standards,Technical Specifications or InternationalStandardized Profiles (1SPs).
6.1Introduction
A process assessment model is related to one or more process reference models. It forms the basis forthe collection of evidence and rating of a process quality characteristic.
A process assessment model provides a two-dimensional view of a process quality characteristic.In onedimension, it describes a set of processes defined in the related process reference model(s); this is termedthe process dimension. In the other dimension, the process assessment model describes the processattributes and the process quality levels defined in the selected process measurement framework; thisis defined as the process quality dimension.The relationship is shown diagrammatically in Figure 1(process dimension on the X axis, and process quality dimension on the Y axis).
