BS ISO IEC 33004-2015 pdf free download – Information technology — Process assessment — Requirements for process reference, process assessment and maturity models.
This International Standard sets out the requirements for process reference models, process assessmentmodels, and maturity models. The requirements defined in this International Standard form a structurewhich specifies
a) the relationship between the classes of process model associated with the performance ofprocess assessment,
b) the relationship between process reference models and prescriptive/normative models of process performance, as constituted by, for example, the activities and tasks defined in ISO/IEC 122071and ISO/IEC 15288 [2],
c)the integration of process reference models and process measurement frameworks to establish process assessment models,
d) the use of common sets of assessment indicators of process performance and process quality in process assessment models, and
e) the relationship between maturity models and process assessment models and the extent to which a maturity model can be constructed using elements from different process assessment models.

4Requirements for process models
This International Standard sets out the requirements that shall be met by process models used to supportprocessassessment.A processassessment modelshall be based upon asuitable reference source of processdefinitions based on one or more process reference model(s) as described in Clause 5.The requirementsto be met by a process assessment model in order to claim conformance through its relationship withspecific process reference model(s) are defined in Clause 6.A maturity model shall be based on a suitableprocess assessment model(s); requirements for a maturity model are set out in Clause 7.
The requirements for conformance of process assessment models enable comparison of outputs fromassessments using different processassessment modelsbased upon the same processreference model[s).
5Process reference models5.1 Introduction
Clause 5 sets out the requirements for a process reference model.5.2Process reference model purpose and scope
The purpose of a process reference model is to define a set of processes that collectively can support theprimary aims of a community of interest. A process reference model provides the basis for one or moreprocess assessment models.
In order to assure that assessment results are translatable into a set of process profiles in a repeatableand reliable manner, process reference models shall adhere to certain requirements.
5.3 Requirements for process reference models
5.3.1A process reference model shall contain:
a) a declaration of the domain of the process reference model;
b) a description of the relationship between the process reference model and its intended context of use;c) descriptions, meeting the requirements of 5.4, of the processes within the scope of the process
reference model;
d) a description of the relationship between the processes defined within the process reference model.
5.3.2The process reference model shall document the community of interest of the model and theactions taken to achieve consensus within that community of interest:
a) the relevant community of interest shall be characterized or specified;
b) the extent of achievement of consensus shall be documented;
c)if no actions are taken to achieve consensus, a statement to this effect shall be documented.BS ISO IEC 33004 pdf download.
