使い方: Use it to show the ISMS improves, not only fixes nonconformities. Fill the sources and the evaluation rule first, then move existing ideas and audit OFIs in. The main pitfall is a list of ideas with no decision, owner or check that the benefit was achieved.

Continual Improvement Register: [Organization name]

Register of improvement opportunities for the information security management system (ISMS), from every source: audits, management review, incidents, measurement results, staff suggestions, customer feedback and threat intelligence. Each entry is evaluated, decided, owned and tracked to a measured benefit. It supports ISO/IEC 27001:2022 + Amd 1:2024 clause 10.1 (making the ISMS fit better, cover more of what it should and work better over time) and the management review input on improvement opportunities (clause 9.3.2) and the decisions on them (clause 9.3.3). Replace every [bracketed] value and every row marked Example.

1. Purpose and scope

This register records opportunities to make the ISMS of [Organization name] more suitable (fits the organization and its context), more adequate (covers what it needs to) and more effective (achieves its intended results), within the scope in DOC-ISMS-002. It is the list top management reviews when it considers improvement opportunities, and the place where decisions on them are recorded.

2. Sources

Code	Source	Example input
AUD	Internal or external audit OFI	OFI in the internal audit report DOC-ISMS-084
MR	Management review	Decision in DOC-ISMS-085 to improve a process
INC	Incident and post-incident review	Lesson learned in DOC-ISMS-022 that is not a nonconformity
MEA	Measurement and performance results	Trend in DOC-ISMS-081
RSK	Risk assessment	Cheaper or stronger treatment option found
STF	Staff suggestion	Suggestion channel, awareness session feedback
CUS	Customer or interested party feedback	Questionnaire themes, contract requests
THR	Threat intelligence and technology change	Input from the threat intelligence procedure DOC-ISMS-045
BEN	Benchmarking and new guidance	New standard edition, peer practice

3. Triage: improvement or correction

Ask one question at entry: is any requirement (of the standard, of an ISMS policy, of a contract or of the law) not met today? If yes, the item is a nonconformity and follows clause 10.2 through the findings register; if no, it is an improvement and stays here. An item can produce both: a post-incident review may find a broken control (nonconformity) and a better way to detect the same attack (improvement). Split it into two entries and cross-reference them.

4. Evaluation and decision

Score each entry on two scales (Example rule):

Score	Benefit	Ease
3	Reduces a High or Critical risk, closes a customer or legal requirement, or saves significant effort	Within one team's capacity, no budget, under one month
2	Reduces a Medium risk or improves a measured objective	Needs coordination or a small budget, one to three months
1	Convenience or minor efficiency	Needs budget approval, new tooling or more than three months

Priority = Benefit x Ease, from 1 to 9.

Priority	Default decision (Example rule)	Decided by
6 to 9	Approve and plan	ISMS manager when no budget is needed; steering committee otherwise
3 to 4	Approve when capacity allows, or defer with a revisit date	Steering committee
1 to 2	Reject or defer, unless required by a customer, regulator or top management	Steering committee

When an approved improvement changes the ISMS itself (processes, scope, roles), plan it through the ISMS change plan (DOC-ISMS-025, clause 6.3). When it supports an objective, link the objective ID in DOC-ISMS-024.

5. Fields and status

Field	Content
ID	CI-YYYY-NNN
Raised	Date and source code with reference
Description	The opportunity, in one or two sentences
Expected benefit	What will improve and how it will be measured
Benefit, Ease, Priority	Section 4 scores
Decision	Approve, Defer (with revisit date) or Reject (with reason), date and decided by
Owner and due	Accountable person and target date
Status	Proposed, Approved, InProgress, Done, Deferred, Rejected
Benefit review	After completion: was the expected benefit achieved, with evidence

7. Reporting to management review

Measure	Example: Quillmere Analytics Ltd at 2027-04-30, 7 entries

Status	Done 3, InProgress 2, Deferred 1, Rejected 1
Benefit achieved	3 of 3 done entries reviewed as achieved
Decisions needed	CI-2027-004 revisit on 2027-07-01

Check: 2 + 1 + 1 + 1 + 1 + 1 = 7 by source; 5 + 1 + 1 = 7 by decision; 3 + 2 + 1 + 1 = 7 by status.
