Full title and description

ISO/IEC 33002:2015 — Information technology — Process assessment — Requirements for performing process assessment. This International Standard defines the minimum requirements for performing process assessments so that results are objective, consistent, repeatable and representative of the assessed processes.

Abstract

Specifies requirements for planning and conducting process assessments including required inputs, assessment classes, evidence collection and validation, rating and aggregation methods, roles and competence, independence considerations and recordkeeping. The standard supports self-assessment, improvement of process performance, production of process attribute ratings and objective benchmarking between organizations.

Scope

ISO/IEC 33002:2015 is applicable across application domains and organization sizes and specifies the minimum requirements for performing process assessments. It covers requirements for a documented assessment process, selection of assessment class, sampling and evidence strategies, competence of assessors, independence categories and reporting of results. The requirements can be used by organizations to support self-assessment, process improvement and objective benchmarking.

Key topics and requirements

• Documented assessment process with defined activities, tailoring rules and coverage criteria.
• Five core assessment activities: plan the assessment, collect data (gather objective evidence), validate data (sufficiency and representativeness), determine results (apply rating and aggregation methods) and report the assessment.
• Definition of assessment classes (reflecting confidence and coverage) with corresponding evidence and sampling requirements.
• Roles, responsibilities and documented competence requirements for lead assessors and assessment teams.
• Independence and impartiality categories for bodies and personnel to ensure unbiased assessments (informative guidance provided in annexes).
• Traceability between ratings and objective evidence, and requirements for maintaining assessment records and outputs.

Typical use and users

Used by organizations conducting or commissioning process assessments, internal quality and process-improvement teams, external assessment bodies and accredited assessors. Common uses include self-assessment, baseline evaluation for improvement programs, supplier or partner benchmarking, and inputs to capability/maturity evaluations when combined with appropriate measurement frameworks.
