ISO 8000 - Data Quality 62:4.2: 4.2 Process capability levels and process attributes

Process capability is measured on the six-step ordinal scale of ISO/IEC 33020, running from incomplete at the bottom through performed, managed, established and predictable to innovating at the top, that is, from a process that misses its purpose to one under continual improvement. In that framework a process attribute is a property of capability that can be measured, and its rating is a judgement of how far the assessed process achieves it; working out a capability level means looking at, and assessing, the evidence for each attribute. Table 1 links each level with its attributes: performed with PA.1.1 (process performance); managed with PA.2.1 (performance management) and PA.2.2 (work product management); established with PA.3.1 (process definition) and PA.3.2 (process deployment); predictable with PA.4.1 (quantitative analysis) and PA.4.2 (quantitative control); innovating with PA.5.1 (process innovation) and PA.5.2 (process innovation implementation).
