The document from section 1, as you will receive it. Highlighted [[text]] is for you to replace; shaded guidance boxes are for you to delete before approval. The cover and document control pages are in the file.

Purpose

This procedure sets out how [[Organisation Name]] assesses the maturity of its security programme from the inside: how an assessment is planned, who may assess what, how evidence is requested and checked, how the results are validated with the people who run the practices, and how the report reaches the people who decide what to do about it. It ends with the actions tracked to closure and the next assessment planned.

It applies the Security Maturity Model & Scoring Method. That document says what each level needs and how a result is worked out. This one says how to run the assessment so the result can be trusted: no one rates their own work, the targets are set before anyone sees the evidence, the practice owners can add evidence before the result is final, and every action closes only when a re-assessment shows the level moved.

It is written for an organisation without an internal audit department or a large security team. The independence options and the triggers for commissioning an independent assessment are there because small teams cannot always keep assessor and assessed apart. The procedure says what to try first, and what to do when nothing works.

Guidance — delete before approval

Replace every value in [[double brackets]] before approval, and name roles, not people.

The settings in [[double brackets]] (the lead time for requests, the challenge period, the cycle) are the pack's defaults, shared with the Security Maturity Model & Scoring Method. Change them there and here together, before the first assessment.

This document helps you judge how well your security practices work. It is not legal advice, and a maturity result is not a statement that you comply with NIS2, DORA, the GDPR or any standard. Where a law or a certification asks for an assessment or an audit, confirm with counsel or your certification body what it must include.

What an assessment under this procedure is not

MA-19 A maturity result is not an internal audit, a certification or a statement of compliance, and is never presented as one. It can feed the management review, the internal audit programme and the risk register.

An assessment under this procedure is not the ISO/IEC 27001 internal audit (the ISO 27001 Implementation & Certification Readiness pack, P08, covers that), not the internal audit of the ICT risk management framework that DORA Article 6(6) and Delegated Regulation (EU) 2024/1774 Article 28(5) require of financial entities, and not the independent review of the NIS2 Implementing Regulation's Annex point 2.3. Each has its own rules on who may carry it out and what it must cover. The section "Where a law asks for an independent review or audit" sets out how an assessment can feed each of them.

Scope

This procedure applies to:

  • every full assessment of the security programme against the Security Maturity Model & Scoring Method, across its 14 domains and 32 practices;
  • every partial assessment of some domains, run after a significant incident, a major change or a new obligation (MA-17);
  • every re-assessment of a single practice to close an improvement action (MA-18);
  • every assessor, whether a member of staff, a peer from another organisation or a contracted assessor, when they assess against this pack's model.

It does not cover the model itself (the Security Maturity Model & Scoring Method), the evidence to ask for under each practice (the Assessment Evidence Request Checklist), the content of the report (the Maturity Assessment Report Template), or how the improvement plan is sequenced and costed (the Target-State Maturity Roadmap). It does not cover an internal audit, which follows the organisation's audit procedure (P08 for ISO/IEC 27001).

Roles

Role

What they do in this procedure

Assessment sponsor

[[e.g. Chief Operating Officer]]

Commissions the assessment, approves its scope and the target levels before scoring, and takes the report to the approver.

Assessment lead

[[someone who runs none of the practices assessed: e.g. the finance controls manager, internal audit, or a contracted assessor]]

Plans the assessment, assigns assessors so no one rates their own work, decides each result, and writes the report.

Assessor

[[a peer from another function, a reciprocal assessor from a partner organisation, or a contracted assessor]]

Requests and reviews evidence, interviews practice owners, checks samples and proposes a level for each practice assigned to them.

Practice owner

[[the manager who runs each practice]]

Provides the evidence requested by the date set, answers questions, and may add evidence when the draft results are shown.

Head of Information Security

[[e.g. Head of Information Security or CISO]]

Owns the security programme being assessed, coordinates the evidence, proposes the improvement plan from the findings, and owns the tracker. Rates no practice they own or run.

Approver

[[the board, or a board risk committee it has delegated this to; in a two-tier structure, the management board; where there is no board, such as in an owner-managed company, executive management]]

Approves the target levels and the improvement plan, and the investment it needs.

The Head of Information Security is the person most likely to be asked to run the assessment, and the one person who must not rate it. They own the programme being assessed. They coordinate the evidence, explain the practices, and turn the findings into the plan, but they rate no practice they own or run.

Guidance — delete before approval

The assessment lead needs authority more than security knowledge: the standing to ask a manager for records by a date, and to decide a level a manager disagrees with. An internal audit manager, a finance controls manager or a risk manager usually has it. The assessment sponsor should be senior enough to approve targets and take the result to the board or its equivalent.

Who may assess what

The rule

MA-14 No one rates a practice they own or run (P08 IS-07). Where no independent assessor is available for a practice, the result is marked self-assessed and cannot be above Defined until someone independent checks the evidence.

This is P08's IS-07, "Internal auditors must not audit their own work", applied to an assessment. A practice is your own work if you own it, do it, manage the people who do it day to day, or wrote the procedure it follows. Where you can, also avoid having someone rate a practice run by the person they report to.

A self-assessed result is not worthless. It is marked, so the reader knows how far to rely on it, and it is capped at Defined, because Managed needs a check by someone other than the person who does the work. The report counts how many results are self-assessed (MAM-03).

Ways to stay independent, in the order to try them

Work down this list for each practice in step 4. Use the first option that gives an assessor who neither owns nor runs the practice.

Option

How it works

Where it fits

IO-1

A colleague from another function

Someone who runs none of the practices, such as a finance controls manager, a risk manager or internal audit, assesses them, with the security team explaining the practices.

Most practices. Works best with a short briefing on what each level needs.

IO-2

A swap between people or teams

People who run different practices assess each other's, never their own: two members of the security team, or the security team and the IT team.

Teams of two or more, or a security team beside an IT team, where the practices are split between people.

IO-3

A reciprocal assessor

A peer from another organisation assesses your practices, and you assess theirs, under a confidentiality agreement.

Single-person security functions with a trusted peer in the same sector.

IO-4

A contracted assessor

An external assessor rates the practices no one inside can rate independently, or the whole programme.

Where a regulator or customer will rely on the result, or the practices are all run by one person.

IO-5

Self-assessed, marked

The owner rates the practice; the result is marked self-assessed and capped at Defined (MA-14) until someone independent checks the evidence.

Only where none of the above is possible for that practice. The report counts how many results are self-assessed.

Guidance — delete before approval

A colleague from another function (IO-1) is usually the best choice. They know how the organisation works, they can ask for a record and wait for it, and they have no stake in the answer. What they lack is security detail: the briefing below supplies enough of it.

In a reciprocal arrangement (IO-3), agree the scope, the model and the confidentiality terms in writing first. Each side assesses the other against the same model, so the results can be compared over time.

Briefing an assessor who is not a security specialist

Before fieldwork, the lead briefs each assessor from another function (step 5):

  1. Walk through the four levels and what each needs, using the calibration cases.
  2. For each practice assigned to them, read the question, the Defined and Managed evidence and the judging note together.
  3. Agree who explains the practices. The Head of Information Security or the owner may explain what a record is and where it is kept. They do not suggest a level.
  4. Agree where the assessor can ask for help with technical evidence, from someone who does not run the practice.
  5. Settle how notes are written: what was found, what the next level needs, and the evidence seen.

A contracted or reciprocal assessor

Agree these terms with them in writing, before fieldwork:

  • They have not designed, run or advised on the practices they rate in the last [[12]] months.
  • They rate against this pack's model (the Security Maturity Model & Scoring Method) and its rules, so the result can be compared with your own assessments (MA-15). If they use their own model, the result is a break in series.
  • They report a level in words for each practice and domain, and give no overall score or percentage (MA-07).
  • They state the confidence of every result and keep the samples they chose (MA-05, MA-13).
  • They sign a confidentiality agreement, and return or destroy the evidence at the end, keeping only their working papers for the agreed period.
  • They show their competence: [[e.g. experience of assessing security programmes, an audit qualification, sector knowledge]].

When to commission an independent assessment

An internal assessment is the right default for most cycles. Commission an independent assessment, instead of or as well as the internal one, when any of these applies:

Trigger

When it applies

IT-1

A regulator, a certification body or a customer contract requires an independent assessment or audit, or will rely on the result.

IT-2

The management body or the board asks for assurance that does not come from the security function.

IT-3

More than a third of the results would be self-assessed (IO-5), or one person runs every practice.

IT-4

The last two internal assessments gave the same levels and management doubts them, or a significant incident contradicted them.

IT-5

A major change is planned, such as a merger, a new regulated service or a move to a new platform, and the investment decision needs an outside view.

The lead checks the triggers at step 2, and the sponsor decides. Record the decision and the reason in the plan, including a decision not to commission one when a trigger applies. An independent assessor works to this procedure and the Security Maturity Model & Scoring Method, so the result stays comparable with the internal ones (MA-15).

Where a law asks for an independent review or audit

Some laws ask for a review or audit with its own independence and competence rules. A maturity assessment can feed each of them. It meets one only if it is run to that law's own conditions, which this procedure does not set.

Law

Applies to

What it asks

How an assessment relates

NIS2 Implementing Regulation, Annex points 2.3.1, 2.3.2 and 2.3.4

The providers its Article 1 names, such as cloud, data centre and managed service providers

An independent review of the approach to network and information security, by people with audit competence who are not in the line of authority of the area reviewed, at planned intervals and after significant incidents or changes. Where size does not allow that separation, other measures must guarantee impartiality.

An assessment run under this procedure can be part of that review only if its assessors meet those conditions. Otherwise it feeds the review. Record which in the plan.

NIS2 Implementing Regulation, Annex points 2.2.1 and 2.2.3

The same providers

Regular review of compliance with the security policies, reported to the management bodies, at planned intervals and after significant incidents or changes.

The report and its approval keep management informed. The assessment does not replace the compliance review.

DORA Article 6(6); Delegated Regulation (EU) 2024/1774 Article 28(5)

Financial entities, other than microenterprises under Article 6(6); those under the simplified framework under Article 28(5)

An internal audit of the ICT risk management framework by auditors with ICT risk expertise and appropriate independence, in line with the audit plan.

An assessment is not that internal audit. Its results can help the auditors plan, and internal audit may lead it, as in the example, without turning it into the audit.

DORA Article 6(4); Delegated Regulation (EU) 2024/1774 Article 28(4)

Financial entities

Segregation and independence of the ICT risk control function and the internal audit function.

Keep the assessment's assessors separate from those who run the practices. Do not let an assessment replace either function.

DORA Article 6(10)

Financial entities

Verifying compliance may be outsourced, and the entity stays fully responsible for it.

A contracted assessor does not move responsibility. The sponsor still approves the scope and targets, and the approver the plan.

DORA Article 16(1)(g)

Entities under the simplified framework

Regular testing of the plans and measures, and of the effectiveness of the controls.

An assessment can be part of how that testing is planned and recorded.

The NIS2 Implementing Regulation (EU) 2024/2690 binds only the providers its Article 1 names. For other entities under NIS2, its Annex is a useful guide to what an authority may look for, and no more.

Guidance — delete before approval

If you are a financial entity under DORA, agree with your internal audit function how the assessment and the ICT audit share evidence and timing. Do not let the assessment's report stand in for the audit's.

Triggers and inputs

When this procedure runs

MA-17 A full assessment runs at least every [[12]] months. A domain is re-assessed sooner after a significant incident, a major change to the systems or the organisation, or a new obligation that rests on it.

Event

What starts

First step

The last full assessment's fieldwork ended [[12]] months ago, or will have by the next fieldwork date

A full assessment of every domain (MA-17)

Step 1

A significant incident that a practice should have prevented or limited

A re-assessment of the domains the incident touched (MA-17)

Step 1, scope limited to those domains

A major change to the systems or the organisation: a merger, a new platform, a new regulated service, a move of IT to a provider

A re-assessment of the domains the change touches (MA-17)

Step 1, scope limited to those domains

A new obligation that rests on a domain, such as a new law in scope or a customer contract

A re-assessment of that domain, with its target reviewed (MA-09, MA-17)

Step 1, then step 7

An action in the Maturity Findings & Improvement Tracker reaches Ready for re-assessment

A re-assessment of that one practice (MA-18)

Step 28

The management body, a regulator or a customer asks for assurance

A full assessment, or an independent one where a trigger applies (IT-1 to IT-5)

Allow about six weeks from step 1 to the report for a first full assessment, of which fieldwork is two. The EXAMPLE below ran from commissioning on 20 Aug 2026 to the report on 29 Sep 2026.

Procedure steps

Steps are numbered across the phases. "Working days" are Monday to Friday excluding [[public holidays]]. The targets are collected in Timing targets, below.

PH-1 Plan

Led by the assessment lead. Agree the scope, the domains and any practice not applicable with the sponsor; assign an assessor to every practice and check that none rates their own work; set the dates.

Step

Purpose and type of assessment, in the plan

2

Check the triggers for an independent assessment (IT-1 to IT-5). If one applies, the sponsor decides whether to commission an independent assessment instead of, or as well as, this one, and the plan records the decision and the reason.

3

Set the scope: the domains assessed and left out, any practice Not applicable with the reason the sponsor approves (MA-08), and the evidence window (MA-04). Compare the scope, model and window with the last assessment, and note any break in series (MA-15).

With step 2

Scope, exclusions and window, in the plan

4

List the owner of each practice and everyone who runs it. Assign an assessor to every practice so that no one rates a practice they own or run (MA-14, P08 IS-07). Use the independence options in order (IO-1 to IO-5). Count the results that would be self-assessed; more than a third is trigger IT-3.

6

Set the dates: targets approved, requests sent, fieldwork, draft results shown, end of the challenge period, report, executive review and approval. Send the plan to the sponsor for approval.

Assessment lead; Assessment sponsor approves

Before targets are set

The assessment plan, approved

MA-08 A practice is Not applicable only for a reason the sponsor approves and the report states, never because it is weak. A domain with every practice Not applicable is left out of the result, and the report says why.

MA-15 Results are compared over time only when the model, the scope and the evidence window are the same. Any change is a break in series, marked in the report as P11's MR-09 marks a changed metric.

Guidance — delete before approval

The evidence window (MA-04) and the sample size (MA-05) are part of the comparison at step 3. A window of [[12]] months this time and six months last time is a break in series, even if nothing else changed.

PH-2 Set targets

Led by the assessment sponsor. Approve a target level and its reason for every domain, before any evidence is scored (MA-09).

Step

7

Propose a target level for every domain, with its reason: Defined by default; Managed only where an obligation, a risk outside appetite or a business need asks for measurement and independent checking (MA-09). Name the risk or obligation from the registers.

Proposed targets with reasons

8

Approve the targets, in writing and dated, before any evidence is scored. A target changed after scoring has started applies to the next assessment, not this one.

Assessment sponsor

Before step 9

Approved targets, dated

MA-09 The sponsor approves a target level for every domain before any evidence is scored, with a reason: an obligation that rests on it, a risk outside appetite, or a business need. Defined is the default target. Managed is a target only where one of those reasons asks for measurement and independent checking.

Setting targets first is what makes the gap honest. A target set after the results are known tends to settle just below or just at the level found. The dated approval is the evidence that it did not happen.

PH-3 Request evidence

16

Review the proposals for consistency: decide [[3]] practices again from the evidence on file, including one from each assessor, and compare. Discuss and settle every difference before the draft results are shown.

Assessment lead

Last day of fieldwork

Proposals reviewed

MA-02 Evidence decides the level. An interview alone supports Informal at most. A written procedure with no records of it being done supports Informal at most, because Defined needs the practice to be done routinely and leave a record.

MA-05 Where the assessor checks recurring records, the sample is [[3]], or all of them if there are fewer, chosen by the assessor, not by the practice owner; a result is Tested only on such a sample. A sampled record that fails means the level is not met, unless the practice itself caught and corrected the failure and recorded it.

MA-13 Every result states how it was evidenced: Told, Seen or Tested. A level above Informal needs at least Seen; Managed needs Tested.

  • Told (described in an interview, with nothing shown): supports up to Informal.
  • Seen (a document or record was shown, and it says what the practice needs): supports up to Defined.
  • Tested (the assessor chose a sample of records and checked each one against the practice): supports up to Managed.

Running the fieldwork well

  • Start each interview by asking the owner to walk through the last time the practice ran, using the records. It is quicker than asking about the procedure, and it shows whether the procedure is followed.
  • Draw samples from a source the practice does not control: leavers from HR records, not from the access system; findings from the scanner's export, not from the remediation tracker. An incomplete list is itself a finding.
  • Where evidence is promised but not shown, record Told and move on. The owner can add it at validation.
  • A failure the practice caught and recorded itself is evidence that it works. A failure the assessor found is evidence that Defined is not met (MA-05).
  • Write each note as a finding would read: what was found, what the next level needs, and the evidence seen. The Maturity Assessment Report Template uses the notes as they stand.

PH-5 Validate

Decide each result. Where the owner still disagrees, record their view and the reason for the decision (MA-16). The decision is the lead's; the sponsor is told of every disagreement.

Assessment lead

When the challenge period ends

Decided results; disagreements recorded

MA-16 The report goes to the approver (the board, or a board risk committee it has delegated this to; in a two-tier structure, the management board; where there is no board, such as in an owner-managed company, executive management), who approves the targets and the improvement plan. The practice owners see the draft results first and may add evidence within [[5]] working days; the assessment lead decides, and records any disagreement.

Validation is not a negotiation. The owner may add evidence; they may not argue a level up without it. When the owner and the assessor disagree on what a record shows, the lead decides on the criteria in the model, and records both views.

Keep a validation log, one row per practice where anything changed or was disputed:

Report issued

MA-06 A domain's level is the lowest level among its practices that apply. No average, no rounding.

MA-07 There is no overall score, no percentage and no weighting. The result is each domain's level and target, in words, and the gap between them.

MA-10 A domain's gap is its target level minus its current level, counted in levels. A domain at or above its target has no gap.

The report follows the Maturity Assessment Report Template, in eight sections: 1 summary for the approver, 2 scope and method, 3 results by domain, 4 findings, 5 changes since the last assessment, 6 improvement plan, 7 limits of this assessment and 8 decisions requested. Section 7 says what the result does not say, including how many results are self-assessed.

Head of Information Security

With step 23, before the approver's meeting

Roadmap and options

MA-11 Every practice below its domain's target gets an action. Actions take priority first where a risk outside appetite, or an obligation the organisation has recorded as not met, rests on the practice; then the practice at the lower level; then the domain with the larger gap; then domain and practice order. Up to [[5]] actions take priority in one cycle.

MA-12 A practice moves up one level per action. Managed can be claimed only after the practice has run at Defined, with records, for at least [[6]] months. A roadmap never plans a jump of two levels in one step.

PH-8 Approve

MA-18 An action closes only when a re-assessment, by someone other than the action's owner, shows that the practice reached the level the action aimed for.

A re-assessment applies the same criteria, the same confidence rules and the same independence rule as the assessment. It uses records made since the action, so a practice that has only just changed may need time to leave the records Defined asks for. Managed needs [[6]] months at Defined first (MA-12).

Worked example: the distributor's first assessment

EXAMPLE, not part of the procedure. The organisation used throughout the pack is a wholesale distributor with about 900 staff, three warehouses and an online ordering service that takes 60% of its orders. It is an important entity under NIS2 in its Member State, and its board has seven members: the chair, the chief executive, the chief financial officer and four non-executive directors. Its first assessment, ASM-2026-1, covered the whole security programme, all fourteen domains. No practice was Not applicable. Replace every date, role and result with your own.

EXAMPLE. Requests went 10 working days before fieldwork, against the [[10]] the procedure asks. The owners had exactly [[5]] working days to add evidence, and the report followed 1 working day later.

Who assessed what

EXAMPLE. The Internal Audit Manager led the assessment. Internal audit runs none of the security practices, and the Internal Audit Manager already observes the incident exercises as an independent party, so this is option IO-1. The Internal Audit Manager rated 21 practices. The Information Security Manager rated the other 11: those the Head of IT runs, and two practices the Information Security Manager runs.

EXAMPLE. Those two, MP-26 logging and MP-27 alert handling, are self-assessed: no one independent could judge the technical evidence in the time. Both are marked and capped at Defined (option IO-5). That is 2 of 32 results, below the third that would trigger an independent assessment (IT-3). The Head of Information Security owns the programme and rated nothing.

The targets

EXAMPLE. The Chief Operating Officer approved the targets on 21 Aug 2026, before any evidence was scored. Thirteen domains have the default, Defined. One has Managed: incident response and notification. Reason: incidents test the programme most often, NIS2's reporting deadlines rest on the response, and R-01 is outside appetite. Response must be measured and checked by someone other than the team that runs it.

Fieldwork and validation

  • An interview alone. MP-05: HR said every joiner acknowledges the policies at induction, but could not show the records during fieldwork, so the result is capped at Informal (MA-13).
  • Evidence added at validation. MP-30: Raised from Informal at validation, when the owner added the after-action report on 23 Sep 2026. The report it added was approved on 31 Mar 2026, inside the window, so it counted.
  • A disagreement. MP-20: The Head of Information Security held that the earlier reviews count. The lead kept Informal: they left no record of what was removed (MA-02).
  • A failure the practice caught. MP-19: Five leavers sampled from HR records: four had their access removed in time. The fifth was found by the monthly reconciliation and removed, so the practice caught its own failure (MA-05) (P13).

The result and the route to approval

EXAMPLE. 2 of 14 domains are at target: governance and accountability, and awareness and training. There is no overall score. 18 practices are below their domain's target, so there are 18 actions, each one level. The first 5 take priority: MP-04 policy set, MP-10 supplier assessment, MP-24 backups restored, MP-32 recovery tested and MP-14 assessment and follow-up.

EXAMPLE. The Executive Committee reviewed the report on 30 Sep 2026. The Head of Information Security had put every action in the tracker before that review. The board receives the report on 29 Oct 2026 and is asked to approve the targets, the plan and option B, "close the gaps by the 2027 assessment": €59,000 one-off and €18,000 a year. The next full assessment's fieldwork must end by 17 Sep 2027.

Adapting this template

Guidance — delete before approval

Small organisation (one or two people in security): keep the independence rule, the targets set before scoring and the challenge period; they are what makes the result trustworthy. Use a colleague from another function as lead and assessor (IO-1). A reciprocal assessor (IO-3) can rate the technical practices. Assess some domains each year if all 14 at once is too much, as long as each is assessed within [[12]] months.

Organisation with internal audit: internal audit can lead the assessment, as in the example. Keep it separate from the audit itself: a different plan, a different report and the statement that the result is not an audit (MA-19).

Regulated entity (NIS2, DORA): record in the plan whether the assessment is meant to feed an independent review or an ICT audit, and check with [[legal or compliance]] whether its assessors meet that law's independence and competence conditions.

Several business units: run one assessment per unit with the same model, window and sample, and report each unit's profile. Do not combine units by averaging (MA-06, MA-07).

Definitions

Term

Meaning in this procedure

Action

The work that will move one practice up one level, with an owner, a due date and the evidence that will show it is done.

Assessment lead

The person who plans the assessment, assigns assessors, decides each result and writes the report. Independent of the practices they rate.

Break in series

A change to the model, the scope or the evidence window that means a result cannot be compared with an earlier one. It is marked, as P11's MR-09 marks a change to a metric (MA-15).

Confidence

How a result was evidenced: Told, Seen or Tested (MA-13).

Domain

One area of the security programme, such as risk management or identity and access, made up of two to three practices (DM-01 to DM-14).

Domain level

The lowest level among a domain's practices that apply. One weak practice limits the domain, and an average would hide it (MA-06).

Evidence

A document or record that shows a practice is done as the level requires. Interviews explain evidence; they are not evidence of Defined or Managed on their own (MA-02).

Evidence window

The period records must fall in to count: the [[12]] months up to the last day of fieldwork, or the practice's own last cycle where it runs less often than that (MA-04).

Finding

A practice below its domain's target, written as what was found, what the level needs, and the evidence seen.

Gap

The number of levels between a domain's level and its target: 0 when the target is met, up to 3 (MA-10).

Independent

Said of an assessor who neither owns nor runs the practice they rate, and did not write its procedure (MA-14).

Level

One of the four levels of the scale: Not in place, Informal, Defined or Managed. The scale is P01-A09's, and P11 uses it too.

Maturity

How reliably a security practice is done: whether it happens at all, whether it depends on particular people, whether it is written down and leaves a record, and whether it is measured, checked and improved. It describes how the practice works, not how exposed the organisation is today.

Practice

One thing the programme does, stated as a question with the evidence each level needs (MP-01 to MP-32). Practices are what the assessor rates.

Pressing

Said of a practice on which a risk outside appetite, or an obligation the organisation has recorded as not met, rests. Its action takes priority (MA-11).

Re-assessment

Checking a practice again after its action closes, by someone other than the action's owner, to confirm the level moved (MA-18).

Sample

The records the assessor chooses, not the practice owner, to check that a practice is done as its level requires (MA-05).

Self-assessed

A result given by someone who owns or does the practice. It is marked as such and cannot be above Defined until someone independent checks the evidence (MA-14).

Sponsor

The member of management who commissions the assessment, approves its scope and targets, and receives the report.

Target

The level management decides a domain should reach, set before the evidence is scored, with the reason for it (MA-09).

Working day

Monday to Friday, excluding [[public holidays where you are]].
