How should organisations use an IT maturity model to prioritise improvement work?

Use the model to establish a baseline, then compare current practices against the maturity levels that matter most for your environment. Focus first on the gaps that create the most operational risk or block standardisation. The point is not to score well for its own sake, but to turn assessment into a practical roadmap for sequencing change and measuring progress over time.

How a maturity model should guide prioritisation, not just assessment

A maturity model is useful only if it turns a snapshot into decision-making. Treat the score as a baseline, then separate cosmetic gaps from the ones that affect risk, scale, standardisation, or delivery speed. The most valuable work usually sits where an immature practice creates repeated manual effort, weak control consistency, or an inability to operate reliably at the next stage of growth.

The model should therefore be read as a sequencing tool. A low maturity score is not automatically the highest priority; a higher-value gap is one that blocks multiple other improvements, such as missing ownership, unclear policy, or no repeatable control evidence. That makes prioritisation less about chasing the biggest numeric delta and more about fixing the constraints that stop the organisation from progressing.

Good prioritisation also depends on choosing the maturity dimensions that matter for the environment, rather than treating every dimension as equally important. A finance team, for example, may prioritise control evidence and access governance before more advanced automation, while a smaller team may first need standard operating procedures and role clarity. The model works best when it reflects the organisation’s operating reality, not just an abstract ideal state.

What to compare against the model when building the roadmap

Use the model to compare current practice with the target state in a way that is specific enough to drive action. The most useful comparison is not “where are we now?” in the abstract, but “which practices are repeatable, which are inconsistent, and which are missing entirely?” That exposes whether the real gap is process design, ownership, tooling, or governance.

Translate each gap into an improvement theme with a clear business or operational effect. If the issue is that teams handle the same control differently, the improvement is standardisation. If the issue is that work cannot be evidenced, the improvement is measurement and traceability. If the issue is that every change needs manual intervention, the improvement is automation or better workflow design. This makes the roadmap actionable rather than descriptive.

When multiple gaps exist, rank them by dependency. Some fixes unlock later work, such as defining a consistent policy before trying to automate enforcement. Others reduce immediate risk, such as closing a process that leaves critical controls ad hoc. A maturity model is most useful when it helps you decide not only what to do, but what to do first.

For teams building a broader security improvement plan, a CIS Controls v8 lens can help convert maturity gaps into concrete safeguard work, especially where the model shows weakness in inventory, access, logging, or secure configuration.

From maturity scoring to measurable improvement

A maturity model should produce a roadmap with observable outcomes. Each planned improvement needs a way to show that practice has changed, not just that a workshop was completed or a policy was published. That usually means defining a small set of measures for coverage, consistency, and time to execute the control or process.

Measure progress at the level of behaviour, not just documentation. For example, if the roadmap calls for standardisation, look for reduced exception handling, fewer variants of the same process, and less dependence on a few individuals. If the roadmap calls for control maturity, look for evidence that the control can be repeated, reviewed, and audited without heroic manual effort.

This is where maturity models are often misused. Organisations sometimes treat the model as a scorecard for reporting up rather than a tool for sequencing change. That leads to broad, unfocused programmes that chase higher scores without fixing the practical bottlenecks that slow delivery or increase risk. The better approach is to tie each maturity step to a concrete operational benefit.

Standards & Framework Alignment

This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.

CIS Controls v8, OWASP SAMM and NIST CSF 2.0 set the technical controls, while ISO/IEC 27001:2022 defines the regulatory obligations.

Framework	Control / Reference	Relevance
CIS Controls v8	CIS-5 — Account Management	Maturity prioritisation often starts with account and control consistency gaps.
Recommendation — Use CIS Controls to prioritise the control gaps that most reduce operational risk.
OWASP SAMM	2.0 — Software Assurance Maturity Model	The question is explicitly about using a maturity model to plan improvement work.
Recommendation — Map current practices to SAMM to turn maturity gaps into a sequenced improvement roadmap.
NIST CSF 2.0	GV.OV-01 — Organizational Context is Established	Prioritisation depends on linking maturity targets to the organisation's operating context.
Recommendation — Align maturity targets to the organisation's context before ranking improvement work.
ISO/IEC 27001:2022	A.5.1 — Policies for information security	Maturity roadmaps often begin by formalising policy and governance foundations.
Recommendation — Use Annex A policy controls to close governance gaps before automating execution.

Practitioner Guidance

What to prioritise: Start with the gaps that either raise operational risk or prevent consistent delivery across teams. A maturity increase is most valuable when it removes a recurring failure point, standardises a control, or unlocks a later improvement.

What to verify: Check that the maturity model actually matches the environment you are managing. If the dimensions do not reflect your main operating risks, the resulting roadmap will be tidy but misaligned.

Decision rule: If a gap is mainly cosmetic, defer it. If a gap affects repeatability, accountability, or scale, treat it as a roadmap priority even if the score difference looks small.

Practitioner takeaway: The model is not the goal, the improvement sequence is. Use it to identify the smallest set of changes that make the organisation more consistent, more measurable, and less dependent on manual work.
