“How mature is our service management?” is a question most IT leaders have asked at some point. Usually it comes up when something has gone wrong, when a new tool is on the horizon, or when the board wants to know whether IT is getting better.
A maturity assessment answers that question properly. Done well, it gives you an honest picture of where you are, where the real gaps sit, and which improvements will make the biggest difference first. Done badly, it produces a long report that nobody acts on.
Here is what a good assessment actually tells you, and how to turn the results into progress.
What a maturity assessment looks at
An assessment reviews your service management practices against good practice, typically ITIL, and scores each one on a simple scale. The scale usually runs from practices that are informal or reactive, through to practices that are defined, measured and continually improved.
The important word there is practices, not just processes. A good assessment looks at how work really happens: the people involved, the information they use, the tools that support them and the way the practice connects to others. A process that looks fine on paper but is ignored in day-to-day work should not score well.
What it tells you
Where you are genuinely strong
Most organisations have one or two practices that work well. Recognising them matters. They are proof that improvement is possible, and they often hold lessons that can be applied elsewhere.
Where the gaps really are
The biggest gaps are not always the ones people expect. Teams often worry about incident management, only to find that the real weakness sits upstream, in poor change control or a configuration database nobody trusts.
How your practices connect
Practices rarely fail in isolation. A good assessment shows the knock-on effects, for example how weak problem management keeps feeding the same incidents back to the service desk.
What to fix first
This is the most valuable output. Not every gap deserves equal attention. The aim is a short, prioritised roadmap that focuses on improvements with clear value and realistic effort.
Getting the most from an assessment
- Be honest about the purpose. An assessment used to judge teams invites defensive answers. One used to help them improve gets the truth.
- Talk to the people doing the work. Workshops and interviews with service desk analysts, engineers and practice owners reveal far more than documents alone.
- Look at evidence. Sample real tickets, changes and reports. They show what actually happens.
- Keep the scoring simple. A clear five-point scale that everyone understands beats a complex model that needs explaining.
Turning results into action
The assessment is only the starting point. To make it count:
- Pick two or three priorities from the roadmap, not ten.
- Give each one an owner and a realistic timescale.
- Agree how you will measure progress, using a small number of meaningful measures.
- Reassess in six to twelve months to see what has improved and reset priorities.
Repeated over time, assessments become a simple and powerful way to show steady improvement, both to your own teams and to the wider business.
