21、chnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical
22、activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical c
23、ommittee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulat

30、 An integral part of conducting an assessment is to use a process assessment model that is constructed for that purpose, is related to a process reference model and is conformant with ISO/IEC 15504-2, which sets out the minimum requirements for performing an assessment in order to ensure consistency
31、 and repeatability of the ratings. A process reference model cannot be used alone as the basis for conducting consistent and reliable assessments of process capability because it requires greater detail to indicate process performance and capability. Therefore: the descriptions of process purpose an
32、d process outcomes provided by a process reference model need to be supported with a comprehensive set of indicators of process performance; and the capability levels and process attributes defined in ISO/IEC 15504-2 and its associated rating scale need to be supported with a set of indicators of pr
33、ocess capability. This additional detail describes a process reference model in terms of a process assessment model that can enable the assessment of consistent and repeatable ratings of process capability. This Process Assessment Model contains a set of indicators to be considered when interpreting
34、 the intent of its Process Reference Model. These indicators may also be used when implementing a process improvement program or to help evaluate and select an assessment model, method, methodology or tools. The Process Reference Model defined in ISO/IEC 15288:2008 has been used as the basis for the
35、 Process Assessment Model in this part of ISO/IEC 15504. As an exemplar, this Process Assessment Model embodies the core characteristics that could be expected of any Process Assessment Model consistent with ISO/IEC 15504-2. Nevertheless, use of this Process Assessment Model is not required to meet
36、the requirements of ISO/IEC 15504; any other process assessment models meeting the requirements of ISO/IEC 15504-2 may be used in a conformant assessment. This part of ISO/IEC 15504 has a similar structure to Part 5. It may be used in conjunction with Part 5 for joint assessment of system life cycle
37、 processes and software life cycle processes. This part of ISO/IEC 15504 uses the classification structure of the information work products used in ISO 15289 Systems and software engineering Content of systems and software life cycle process information products (Documentation) as a basis for the Ge
38、neric Work Products. Within this part of ISO/IEC 15504: Clause 4 provides a detailed description of the structure and key components of a process assessment model, which includes two dimensions: a process dimension and a capability dimension. Assessment indicators are introduced in this clause; Clau
39、se 5 addresses the process dimension. It uses process definitions from ISO/IEC 15288 to designate the Process Reference Model. The processes of the Process Reference Model are described in the Process Assessment Model in terms of purpose and outcomes and are grouped in four process categories. The P
40、rocess Assessment Model expands the Process Reference Model process definitions by including a set of process performance indicators called base practices for each process. The Process Assessment Model also defines a second set of indicators of process performance by associating work BS ISO/IEC 1550
41、4-6:2013 ISO/IEC 15504-6:2013(E) ISO/IEC 2013 All rights reserved viiproducts with each process. Clause 5 is also linked directly to Annex B, which defines the work product characteristics; Clause 6 addresses the capability dimension. It duplicates the definitions of the capability levels and proces
42、s attributes from ISO/IEC 15504-2, and expands each of the nine attributes through the inclusion of a set of generic practices. These generic practices belong to a set of indicators of process capability, in association with generic resource indicators, and generic work product indicators. Annex B i
43、s also linked directly to Clause 6 as it defines the work product characteristics; Annex A provides a statement of conformance of the Process Assessment Model to the requirements defined in ISO/IEC 15504-2; Annex B provides selected characteristics for typical work products to assist the assessor in
44、 evaluating the capability level of processes; Annex C contains style guides for defining base practices, work products and generic practices for adjusting the Process Assessment Model, and guidance explaining how to expand or adapt the model; and The bibliography contains a list of informative refe
45、rences.

46、sessment Model, conformant with the requirements of ISO/IEC 15504-2, for the assessment of process capability of system life cycle processes. The Process Dimension of this Process Assessment Model is based upon the Process Reference Model contained in ISO/IEC 15288. This part of ISO/IEC 15504 provid
47、es a new Process Dimension for the Process Assessment Model derived from the revised Process Reference Model contained in ISO/IEC 15288:2008. The scope of this part of ISO/IEC 15504 is consistent with the scope of ISO/IEC 15504-5 in order to assist situations where assessment is being made of both s
48、ystem and software life cycle processes. NOTE Users of this part of ISO/IEC 15504 can freely reproduce the detailed descriptions contained in the exemplar assessment model as part of any tool or other material to support the performance of process assessments, so that it can be used for its intended
49、 purpose. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
