In organisational change management, maturity refers to the extent to which an organisation has repeatable, defined and continuously improving practices for managing the people side of change.
A change practitioner typically estimates maturity to understand receptiveness to formal change management, to calibrate the level of rigour needed, and to identify capability-building priorities.
Assessment approach
Maturity estimation is usually performed as a triangulated assessment rather than a single self-rating. Common data sources include:
Structured interviews with executives, sponsors, project/program leaders, HR, Communications, and frontline managers, focused on decision rights, sponsorship behaviours, and past change outcomes.
Surveys to capture perceptions at scale (e.g., consistency of change impacts analysis, communication effectiveness, manager enablement, and reinforcement).
Artefact and process review, such as business cases, stakeholder maps, training plans, communications calendars, readiness assessments, benefit realisation plans, and lessons learned repositories.
Outcome and operational metrics, including adoption/usage measures, productivity dips, employee experience indicators, change saturation and rework rates, and benefit realisation performance.
Evidence is then mapped to a reference model (or more than one) to produce an overall maturity rating and a profile by capability area. Practitioners often accompany the rating with a short narrative explaining supporting evidence, observed strengths and constraints, and a practical roadmap (e.g., 90–180 days) for moving to the next maturity level.
Commonly referenced models and standards
Prosci Change Management Maturity Model – a five-level model ranging from “absent/ad hoc” to “organisational competency”, used to benchmark how consistently change management is applied across projects. Prosci overview
Changefirst Enterprise Change Management Maturity Model – an enterprise capability model that links maturity to governance, sponsorship, and organisational capacity to absorb change (often presented as four levels). Changefirst ECM paper (PDF)
ACMP Standard for Change Management – a professional standard describing generally accepted practices and process groups; it can be used as an assessment checklist to evaluate whether key practices are present, defined, and repeatable. ACMP Standard page
In addition, practitioners sometimes use generic process maturity references (e.g., staged maturity concepts such as levels 1–5) as an organising metaphor when communicating maturity to executives. CMMI maturity levels
Where to seek additional support
Support for maturity assessment and capability building is commonly sought from:
Professional bodies and communities of practice, such as the Association of Change Management Professionals (ACMP)
Training and certification providers and their tools, including Prosci
Specialist consultancies and diagnostic tools that provide structured maturity assessments, for example Changefirst maturity assessment
Internal governance functions (PMO/PPM, HR, L&D, Internal Communications, Risk/Compliance) that can embed change management expectations into delivery and people processes.
Academic and practitioner literature (e.g., peer-reviewed organisational change journals) for method selection and measurement validity.
Common pitfalls and errors
Common errors in maturity assessment include:
relying solely on leadership self-assessment without independent evidence;
rating maturity based on the existence of templates rather than consistent use and measurable outcomes;
ignoring organisational context such as change saturation, resourcing constraints, or regulatory delivery requirements;
treating maturity as a single score and missing variation across business units, functions, or geographies;
producing a maturity report without an actionable, funded roadmap and ownership for capability development.
