11、 the process to be followed in conducting assessments. This International Standard provides an example of a process assessment model for software testing for use in performing a conformant assessment in accordance with the requirements of ISO/IEC 33002. An integral part of conducting an assessment i

12、s to use a process assessment model (PAM) related to a process reference model (PRM) and conformant with the requirements defined in ISO/IEC 33004. A process reference model cannot be used alone as the basis for conducting a consistent and reliable assessment of process capability since the level of

13、 detail is not sufficient. Therefore, the description of the process purpose and process outcome(s) provided by the process reference model needs to be supported with a comprehensive set of indicators of process performance, and the capability levels and process attributes defined in ISO/IEC 33020 a

14、nd its associated rating scale need to be supported with a set of indicators of process capability. Used in this way and in conjunction with a documented process, consistent and repeatable ratings of process capability is possible. This International Standard, a process assessment model for software

15、 testing, contains a set of indicators to be considered when interpreting the intent of the process reference model. These indicators may also be used when implementing a process improvement program or to help evaluate and select an assessment model, methodology, and/or tools. The process reference

16、model defined in ISO/IEC/IEEE 29119-2 has been used as the basis for the ISO/IEC 33063 exemplar process assessment model for software testing. The following are provided within this International Standard: Clause 4 provides a detailed description of the structure and key components of the process as

17、sessment model, which introduces the following two dimensions: a) process dimension; b) capability dimension. Assessment indicators are also introduced in this Clause; Clause 5 addresses the process dimension. It uses process definitions from ISO/IEC/IEEE 29119-2 to identify a process reference mode

18、l. The processes of the process reference model are described in the process assessment model in terms of purpose and outcomes. The process assessment model expands the process reference model process definitions by including a set of process performance indicators called base practices for each pro

19、cess. The process assessment model also defines a second set of indicators of process performance by associating work products with each process; Clause 6 addresses the capability dimension. It duplicates the definitions of the capability levels and process attributes from ISO/IEC 33020 and expands

20、each of the attributes through the inclusion of a set of generic practices. These generic practices belong to a set of indicators of process; Annex A provides a statement of conformance of the process assessment model for software testing to the requirements defined in ISO/IEC 33004; Annex B provide

21、s a guideline on how the planning and scoping of an assessment is done with this process assessment model for software testing; ISO/IEC 2015 All rights reserved vBS ISO/IEC 33063:2015ISO/IEC 33063:2015(E) NOTE As the processes described in this model are generic when practically applied to an assess

22、ment, they have to be applied to the different test phases or test levels or test types encountered in the project which is to be assessed. The multiple applications of the processes have to be documented in the assessment scope. It also provides guideline on the use of additional processes from oth

23、er process assessment models.

25、t model for software testing 1 Scope This International Standard defines a process assessment model that meets the requirements of ISO/IEC 33004 and that supports the performance of an assessment of process capability using the process measurement framework defined in ISO/IEC 33020. The process asse

26、ssment model provides indicators for guidance on the interpretation of the process purposes and outcomes as defined in ISO/IEC/IEEE 29119-2 and the process attributes as defined in ISO/IEC 33020, and provides guidance, by example, on the definition, selection, and use of assessment indicators. A pro

27、cess assessment model comprises a set of indicators of process performance and process capability. The indicators are used as a basis for collecting the objective evidence that enables an assessor to assign ratings, following the requirements of ISO/IEC 33002. The set of indicators included in this

28、International Standard is not intended to be an all-inclusive set nor is it intended to be applicable in its entirety. Subsets that are appropriate to the context and scope of the assessment should be selected. The process assessment model in this International Standard is directed at assessment spo

29、nsors and competent assessors who wish to select a model and associated documented process method for assessment (for either capability determination or process improvement). Any process assessment model for software testing meeting the requirements defined in ISO/IEC 33004 concerning models for pro

30、cess assessment may be used for assessment. Different models and methods might be needed to address differing business and testing needs. This assessment model is provided as an exemplar of a model meeting all the requirements expressed in ISO/IEC 33004. 2 Normative references The following document

35、includes examples of assessment indicators. The process reference model (PRM) defined in ISO/IEC/IEEE 29119-2, together with the process attributes defined in ISO/IEC 33020, establish the process assessment model used as a common basis for performing assessments of software testing process capabilit

36、y, allowing for the reporting of results using a common rating scale. The process assessment model is a two-dimensional model of process capability. In one dimension, the process dimension, the processes are defined and classified into process categories. In the other dimension, the capability dimen

37、sion, a set of process attributes grouped into capability levels is defined. The process attributes provide the measurable characteristics of process capability. Figure 1 Relationship between the process assessment model and its inputs Figure 1 shows the relationship between the general structure of

38、 the process assessment model, ISO/IEC 33020 and ISO/IEC/IEEE 29119-2. The process reference model and the capability dimension defined in ISO/IEC 33020 cannot be used alone as the basis for conducting reliable and consistent assessments of process capability since the level of detail provided is no

39、t sufficient. The descriptions of the process purpose and outcomes in the process reference model, and the process attribute definitions in ISO/IEC 33020, need to be supported with a comprehensive set of indicators of process performance and process capability that are used for assessment performanc

40、e. The exemplar process assessment model for software testing defined in ISO/IEC 33063 is conformant with the ISO/IEC 33004 requirements for a process assessment model, and can be used as the basis for conducting an assessment of software testing process capability.2 ISO/IEC 2015 All rights reserved
