BS ISO-IEC 33020-2015 pdf free download – Information technology — Process assessment — Process measurement framework for assessment of process capability.
4 overview
The capability to perform a process to a specific level of performance depends on well establishedprinciples. This International Standard sets out those principles that are common to all domains. Theprocess capability measurement framework described in this International Standard is expressed interms of a set of process attributes.Each process attribute is definedin terms of a set of process attributeoutcomes which can be evaluated to indicate the extent of achievement of the process attribute. Theprocess attributes are organised into process capability levels, ranging from Incomplete (in which theprocess does not achieve its defined process outcomes) to Innovating (in which the process is continuallyimproved to respond to organizational change].
The result of an assessment,using a process assessment model that incorporates this processmeasurement framework, will be a set of process profiles – ratings of the achievement of the set ofprocess attributes for each process in the scope of the assessment. The result can also be expressedin terms of the capability level ratings achieved for each process in the assessment scope. A capabilitylevel rating does not guarantee that an organization will perform its processes at any given processcapability level, simply that it is capable of performing its processes at that level.
5A process measurement framework for process capability
5.1 Introduction
This clause defines a process measurement framework for the assessment of process capability,conformant with the requirements of lSO/IEC 33003.This process measurement framework provides aschema that can be used to construct a process assessment model for assessing process capability.
Within this process measurement framework, the measure of capability is based upon a set of processattributes.Each process attribute defines a measurable property of process capability.The extent ofprocess attribute achievement is characterised on a defined rating scale. The process capability levelfor an assessed process is derived from the set of process attribute ratings represented in the processprofile.
The achievement of one process attribute may be associated with the achievement of another processattribute wwithin the process measurement framework.
5.2Process capability levels and process attributes
Process capability is defined on a six point ordinal scale that enables capability to be assessed from thebottom of the scale, Incomplete, through to the top end of the scale, Innovating.The scale representsincreasing capability of the implemented process, from failing to achieve the process purpose throughto continually improving and able to respond to organizational change.
5.2.1 Process capability Level 0: Incomplete process
The process is not implemented, or fails to achieve its process purpose.
At this level there is little or no evidence of any systematic achievement of the process purpose.
5.2.2 Process capability Level 1: Performed process
The implemented process achieves its process purpose.The following process attribute demonstratesthe achievement of this level.
5.2.2.1 PA 1.1 Process performance process attribute
The process performance process attribute is a measure of the extent to which the process purpose is achieved. As a result of full achievement of this process attribute:
a) The process achieves its defined process outcomes.
5.2.3 Process capability Level 2: Managed process
The previously described Performed process is now implemented in a managed fashion (planned, monitoredandadjusted)anditsworkproductsareappropriatelyestablished,controlledandmaintained.BS ISO-IEC 33020 pdf download.
