12、:2015(E) Foreword ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards throu

13、gh technical committees established by the respective organization to deal with particular fields of technical 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

14、take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the diffe

15、rent approval criteria needed for the different types of document should be noted.

20、re objective, consistent, repeatable, and representative of the assessed processes. The requirements help to ensure that the assessment output is self-consistent and to provide evidence to substantiate the ratings and to verify compliance with the requirements. Process assessment is applicable in th

21、e following circumstances: by or on behalf of an organization with the objective of understanding the state of its own processes for process improvement; by or on behalf of an organization with the objective of determining the suitability of its own processes for a particular requirement or category

22、 of requirements; by or on behalf of one organization with the objective of determining the suitability of another organizations processes for a particular purpose, contract, or category of contracts. This International Standard is applicable across all application domains and sizes of organizations

23、. Appropriate methods, techniques, and tools can be used to enable the assessment process to be effective and efficient. This International Standard is part of a set of International Standards designed to provide a consistent and coherent framework for the assessment of process quality characteristi

24、cs, based on objective evidence resulting from implementation of the processes. The framework for assessment covers processes employed in the development, maintenance, and use of systems across the information technology domain and those employed in the design, transition, delivery, and improvement

25、of services. The set of International Standards, as a whole, addresses process quality characteristics of any type. Results of assessment can be applied for improving process performance, or for identifying and addressing risks associated with application of processes. The ISO/IEC 330xx family of St

26、andards defines the requirements and resources needed for process assessment. The overall architecture and content of the series is described in ISO/IEC 33001:2015. Several International Standards in the ISO/IEC 330x x f amily of st andards for process assessment are intended to replace and extend p

27、arts of the ISO/IEC 15504 series of Standards. ISO/IEC 33001, Annex A provides a detailed record of the relationship between the ISO/IEC 330xx family and the ISO/IEC 15504 series.

28、Requirements for performing process assessment 1 Scope This International Standard defines the minimum set of requirements for performing an assessment that will ensure assessment results are objective, consistent, repeatable, and representative of the assessed processes. The requirements defined in

29、 this International Standard can be used by or on behalf of an organization to a) facilitate self-assessment, b) provide a basis for improving process performance and mitigating process-related risk, c) produce a rating of the achievement of the relevant process quality characteristic, and d) provid

30、e an objective benchmark between organizations. This International Standard is applicable across all application domains and sizes of organization. NOTE An organization can implement a set of integrated processes in a system. 2 Normative references The following documents, in whole or in part, are n

T

35、he requirements help to ensure that the assessment output is self-consistent and provides evidence to substantiate the ratings. 4.1 General requirements The assessment shall be conducted according to a documented assessment process. The documented assessment process shall be capable of meeting the a

36、ssessment purpose and shall be structured in a manner that ensures that the purpose for performing the assessment is satisfied, in terms of the rigour and independence of the assessment and its suitability for the intended use. The documented assessment process shall prescribe a set of activities an

37、d tasks to be performed that meet all of the requirements defined in this International Standard. Specifically, the documented assessment process shall: identify as a minimum, the assessment activities as defined in 4.2; identify as a minimum the roles, responsibilities and competencies as defined i

38、n 4.3; identify the classes of assessment for which the documented assessment process can be applied, and the nature and extent of tailoring associated with each class addressed by the documented process; define the criteria for ensuring coverage for both the defined organizational scope and the def

39、ined process scope for the assessment, in terms of the strategy for collecting and analysing data; identify the rating method(s) to be used in rating process attributes; identify or define the aggregation method(s) to be used in determining ratings. Classes of assessment are described in 4.6. They r

40、eflect different levels of confidence in the results of the assessment. Different categories of independence for different types of bodies and personnel are described in Annex A, with criteria for their use. The documented assessment process shall contain at minimum the following activities:2 ISO/IE

42、quired inputs specified in this standard (refer to 4.4); b) class of assessment (refer to 4.6); c) category of independence of the body performing the assessment, the lead assessor and the other members of the assessment team (refer to Annex A) d) communications to the personnel involved in the asse

43、ssment; e) identification of the documented assessment process including: 1) the strategy and techniques for the selection, identification, collection and analysis of objective evidence and data, to satisfy any requirements for coverage of the organizational scope or the process scope of the assessm

44、ent as defined for the class of the assessment (refer 4.6); 2) the approach to derive an agreed process attribute rating, where relevant. f) activities to be performed in performing the assessment; g) resources and schedule assigned to these activities; h) identification and definition of roles and

45、responsibilities of the participants in the assessment; i) criteria to verify that the requirements of this International Standard have been met; j) description of the planned assessment outputs. Roles and responsibilities for process assessment shall be assigned and communicated to personnel impact

46、ed by the assessment. The plan for the assessment shall be approved by the assessment sponsor, and the approval shall be documented. 4.2.2 Collect the data The data collected shall be sufficient to provide coverage of the organization scope and the process scope for the assessment, as specified for

47、the selected class of the assessment. Data shall be collected on the basis of direct or indirect evidence that shall be sufficient for the class of assessment (refer to 4.6). Evidence required for evaluating the processes within the assessment scope and additional information shall be collected in a

48、 systematic manner applying at minimum the following: a) a correspondence between the organizational units processes and the elements in the process assessment model, specified in the assessment scope, shall be established; b) each process identified in the assessment scope shall be assessed on the

49、basis of objective evidence; c) objective evidence shall be identified and gathered to provide the basis for verification of the ratings; d) objective evidence gathered for each process attribute for each process assessed shall be sufficient to meet the assessment purpose, assessment scope and class of assessment; e) objective evidence collected for each process shall be representative of the implementation of the process across the organizational scope
