What is an ITIL maturity assessment?
The ITIL Maturity Model is PeopleCert's tool for objectively assessing two things: how capable you service management practices are, and how mature your governance and management system for IT has become. It looks across all four dimensions of service management, so it covers your people and structures, your technology and information, your value streams and processes and your supplier relationships.
As assessment applies that module to your organisation. As accredited assessor review your evidence, interview your people, scores your capability and maturity against the model, provides an overview of what is working and what needs improvement, and sets out how this can be achieved.
The purpose is not to grade you. It is to give you a baseline, a prioritised set of improvements, and a fixed reference point you can measure progress against next year.
Assessments using the ITIL Maturity Model can only be delivered by PeopleCert Accredited Consulting Partners.
Why does ITIL maturity matter?
Maturity is a measure of how predictably your organisation delivers. On time delivery, productivity, quality, compliance and customer satisfaction all track against it.
PeopleCert's ITIL Performance Benchmarking Survey 2026 found a consistent link between higher organisational maturity and both stronger business performance and greater stakeholder confidence in digital technology. Independent research supports the same conclusion. The practical implication for IT leaders is that maturity is not an abstract score, it is a leading indicator worth measuring and managing.
A high performing IT service function means fewer surprises, clearer ownership, steadier delivery, and a service desk that spends less time firefighting. An ITIL maturity assessment reads those signals, showing where service management stands today and where the next gains will matter most.
In practice, organisations that raise maturity typically see:
- More consistent service delivery
- Faster incident resolution
- Better governance and accountability
- Clearer alignment between IT services and business priorities
- Earlier visibility of service delivery risk, before it escalates

Which assessment is right for you?
PeopleCert defines three types of assessment. The right one depends on how many practices you would like assessed, if certification is a requirement and where your organisation is currently at.
Option 1: High-level maturity assessment
Assesses the maturity of your service value system only. Practice capability is either not assessed, or few than seven practices are in scope.
- Best for: a first assessment, a governance level review or a quick baseline before a larger programme.
- Output: SVS maturity ratings, findings and recommendations for uplift
Option 2: Capability Assessment
Assesses the capability of the specific practices you select, this can be any number, between a single practice through to all 34. The service value system is not assessed.
- Best for: targeted uplift where you already know the problem area, for example service desk, incident, change enablement or knowledge management.
- Output: per practice capability scoring, findings and recommendations for uplift
- Example scope: Incident Management, Problem Management, Change Enablement, Knowledge Management, Asses Management, Service Catalogue Management, Service Desk Management, Service Request Management and Continual Improvement.
Option 3: Comprehensive assessment
Assesses the maturity of your service value system alongside the capability of seven or more practices, with Continual Improvement being mandatory. Includes all SVS components: Guiding Principles, Governance, Service Value Chain, Practices, Continual Improvement, plus at least 7 practices.
- Best for: organisations wanting a full SVS maturity view and a strong baseline for transformation
- Output: detailed report with per-practice findings, SVS component scoring, quick wins, and recommendations for uplift.
- Optional: independent valuation and a Maturity Level certificate issued by PeopleCert.
The five ITIL maturity levels
The ITIL maturity model describes five stages of practice capability and organisational maturity. Assessments score you against these levels so you can see where you sit and what the next step looks like. It is used to show how reliably services are delivered, measured, and improved over time.
- Level 1 (Initial or ad hoc): Work is informal and uneven, and outcomes depend heavily on individual effort. What gets done well gets done because someone made it happen.
- Level 2 (Repeatable): A basic set of activities exists and the practice can be followed more consistently, though this is not yet standardised across teams.
- Level 3 (Defined and documented): The practice has shape, a shared language, and structure, with integrated inputs from other practices. This is where most organisations aim to reach first.
- Level 4 (Managed and measured): Performance is monitored, reviewed, and managed within the wider service management system. You are measuring outcomes, not just activity.
- Level 5 (Optimised and continually improving): Improvement becomes part of the operating habit, rather than a one-off project. Changes are driven by data and tested against value.
Most organisations do not need to reach Level 5 everywhere. A good assessment tells you which practices justify the investment and which are already fit for purpose.
How the assessment works
- Scope and planning: We define the services, practices, timelines, and interview list.
- Document review: We examine policies, processes, templates, reports, metrics, records, and tool configuration.
- Interviews and evidence gathering: We speak with your stakeholders and compare what’s documented with what is actually happening.
- Scoring and analysis: We convert findings into maturity and capability results across the relevant areas in scope.
- Report and recommendations: We deliver findings, quick wins, and an improvement path.
For a closer look at the model itself, see the ITIL maturity model levels, assessments, and how it works. And to understand why many organisations schedule assessments at the start of the year, see why your financial year should start with an ITIL maturity assessment.What you receive after the assessment
A good assessment leaves more than a score. Your report, will include:
- A maturity and capability score across key ITSM capabilities.
- The assessment method and scope, so the result is repeatable next year
- A detailed assessment report with current findings.
- Recommendations that point to practical improvement.
- A roadmap for strengthening IT service management over time (see example report).
Whether your organisation is in Australia, New Zealand, or the UK, your Word-format report also includes:
- Assessment method and scope
- Graphical representations of findings
- Per-practice conclusions
- SVS component results (where applicable)
Optional add-on: Service Improvement Roadmap workshop. Please note, the report itself will provide findings and recommendations, but the roadmap is a separate workshop to create a detailed improvement plan.
Is an ITIL maturity assessment right for us?
An assessment is worth doing when:
- You are planning a service management uplift and need a baseline to justify and measure it
- Leadership is asking for evidence rather than opinion on how IT is performing
- You are entering or renewing a major outsourcing or supplier arrangement
- Service performance is inconsistent and you cannot pinpoint why
- You need external validation for work already completed
- You want to benchmark year on year progress
The model adapts to your context. Whether you run a small internal IT team or a large multi supplier enterprise, the assessment give you clarity on what works, what needs structure and where to focus.

FAQ
What’s the difference between a capability assessment and a maturity assessment?
Capability assesses how well specific ITSM practices achieve their purpose. Maturity assesses the broader Service Value System (governance + management system) and produces the maturity rating used for improvement planning.
Do we need to assess all practices?
Who should be involved from our side?
What evidence do you need?
Policies, processes, templates, metrics/reports, tool configuration, records (incidents/changes/requests), meeting minutes, audit outputs, whatever is relevant and permissible. If documents can’t be shared, we can review them via screen share.
Is the assessment done onsite or remotely?
How long does it take?
- Documentation review: 5 days
- Interviews & evidence: 5 days
- Analysis & report writing: 10–12 days
- Final review & submission: 1 day
