BS ISO/IEC 33020:2015 pdf download-Information technology — Process assessment — Process measurement framework for assessment of process capability.
5.2.5.1 PA 4.1 Quantitative analysis process attribute The quantitative analysis process attribute is a measure of the extent to which information needs are defined, relationships between process elements are identified and data are collected. As a result of full achievement of this process attribute: a) The process is aligned with quantitative business goals; b) Processinformationneedsinsupportofrelevantdefinedquantitativebusinessgoalsareestablished; c) Process measurement objectives are derived from process information needs; d) Measurable relationships between process elements that contribute to the process performance are identified; e) Quantitative objectives for process performance in support of relevant business goals are established; f) Appropriate measures and frequency of measurement are identified and defined in line with process measurement objectives and quantitative objectives for process performance; g) Results of measurement are collected, validated and reported in order to monitor the extent to which the quantitative objectives for process performance are met. NOTE 1 Information needs typically reflect management, technical, project, process or product needs. NOTE 2 Measures may be either process measures or product measures or both.
5.3 Process attribute rating scale Within this process measurement framework, a process attribute is a measureable property of process capability. A process attribute rating is a judgement of the degree of achievement of the process attribute for the assessed process. A process attribute is measured using an ordinal scale as defined below. N Not achieved: There is little or no evidence of achievement of the defined process attribute in the assessed process. P Partially achieved: There is some evidence of an approach to, and some achievement of, the defined process attribute in the assessed process. Some aspects of achievement of the process attribute may be unpredictable. L Largely achieved: There is evidence of a systematic approach to, and significant achievement of, the defined process attribute in the assessed process. Some weaknesses related to this process attribute may exist in the assessed process. F Fully achieved: There is evidence of a complete and systematic approach to, and full achievement of, the defined process attribute in the assessed process. No significant weaknesses related to this process attribute exist in the assessed process. The ordinal scale defined above shall be understood in terms of percentage achievement of a process attribute.
