A useful change log should let a continuity practitioner explain what changed, why it changed, who reviewed or approved it, and which plan version became current. When evaluating BCM software, do not accept “version control” or “audit trail” as self-explanatory features. Ask the vendor to reconstruct a material plan change from its original trigger through the current approved record.
That test shows whether the platform manages change or merely stores successive copies of a document.
In short
Useful change tracking connects the trigger, plan revision, responsible owner, review or attestation, approval when required, current version, and supporting evidence. Evaluate the complete chain with a real scenario. A timestamp or saved version is only one part of the record.
Several records contribute to change control, but they answer different questions.
| Record | Question it should answer |
|---|---|
| Change entry | What material content changed, why, when, and under whose responsibility? |
| Version history | Which plan states existed, and which version is current? |
| Review record | Who checked the content, what did they decide, and what remains unresolved? |
| Attestation | Who confirmed that defined information remained accurate or reported that an update was needed? |
| Approval record | Who accepted a specific version when formal approval was required? |
| Exercise finding | What observed result exposed the need for change? |
| Corrective action | What work remains open, who owns it, and what will demonstrate closure? |
| Audit trail | What sequence of recorded system activity led to an event or result? |
The NIST glossary defines an audit trail as a chronological record that can reconstruct and examine a sequence of activities. That definition comes from an information-security context, but the distinction is useful in BCM. An audit trail may show that a user edited a record. It does not necessarily explain the operational reason, prove that the right person approved the change, or show that a related corrective action was completed.
Do not force all these records into one text field. Evaluate whether the software can keep them distinct and connected.
For a material plan change, the history should be understandable without reopening an email chain or locating the original editor.
| Required evidence | What the software should let you determine |
|---|---|
| Plan identifier and version | Which plan changed and which prior version applied |
| Change summary | Which material content was revised |
| Reason or trigger | Whether the change came from a review, attestation, incident, exercise, BIA update, supplier change, technology change, or another event |
| Responsible owner | Who made or coordinated the change |
| Review or attestation | Who validated the applicable content and what they decided |
| Approval, when required | Who accepted the identifiable version and when |
| Effective version | Which plan is now current |
| Supporting evidence | Which finding, decision, note, ticket, or other record supports the change |
| Open follow-up | Whether a corrective action, retest, exception, or related update remains unresolved |
This table is practitioner guidance, not a universal regulatory checklist. Adapt it to your policies, obligations, plan types, and approval rules.
ISO 22301:2019 describes a documented business continuity management system that is monitored, reviewed, maintained, and continually improved. It does not prescribe the fields above. NIST SP 800-34 Revision 1 provides a more specific public-sector example: it advises federal information-system contingency planners to record plan modifications using the page number, change comment, date, and signature, and to maintain strict version control. That NIST guidance is not a universal requirement for every continuity plan, but it shows why a new filename alone is weak evidence.
Use one realistic plan update and score each capability as pass, partial, or fail.
| Evaluation criterion | Demonstration request |
|---|---|
| Change context | Show where the user records what changed and why |
| Prior state | Retrieve the version that applied before the change |
| Connected evidence | Link or reference the review, attestation, exercise finding, incident, or other trigger |
| Review and comments | Show who reviewed the applicable content and how unresolved comments are handled |
| Version-specific approval | Demonstrate how approval is associated with the version being accepted |
| Open corrective work | Keep incomplete actions visible without presenting the issue as fully closed |
| Current-state control | Identify the plan version users should rely on now |
| Retrieval and reporting | Find the history by plan, date, owner, or trigger and show available export or reporting options |
| Recorded activity | Show which user actions are captured automatically and what the audit trail does not capture |
Do not let the vendor substitute a slide for the workflow. Ask an ordinary user, not only an administrator, to complete the test.

Assume an exercise reveals two issues. A supplier escalation number is obsolete, and the documented manual workaround takes longer than expected.
Ask the vendor to demonstrate how the platform handles both outcomes:
This scenario exposes weak integrations between records. If the software stores only the revised plan, the exercise context disappears. If it records only the finding, the plan may remain wrong. If the corrective action is closed before the plan is updated, reporting can show completion while the operational record remains stale.
Once the organization has defined its materiality, review, approval, and retention rules, software can make the execution easier to control.
BCM Planner allows teams to create or upload plan templates, create and edit recovery plans, and manage plans in one place. Approved BCMMetrics product materials also describe draft, review, complete, and approved statuses, along with review and approval activity. Teams can create exercise templates, record exercise results, and produce reports from captured exercise data.
These capabilities are relevant to controlled plan maintenance. They do not replace governance, and the public product page does not establish that every field or linkage in this article is captured automatically. During a demonstration, use the scorecard above to confirm how BCM Planner handles your required change history, evidence, access, and reporting.
The real value of a change log appears later, when someone who was not involved needs to understand the current plan.
Before buying or renewing BCM software, verify that a practitioner can answer four questions without searching across email, spreadsheets, and disconnected files:
If the platform cannot reconstruct that decision path, it may provide document storage without providing useful change control.
Not necessarily. Typographical corrections and formatting changes may not require the same record or approval path as changes to procedures, responsibilities, dependencies, contacts, suppliers, facilities, or recovery assumptions. Define the threshold in policy rather than leaving it to each editor.
No. Version history shows that different plan states existed. A change entry explains the material revision and its reason. The records are strongest when connected.
There is no universal retention period. Base the decision on applicable law, regulation, contractual commitments, internal records policy, audit cycles, and the operational value of the history. Confirm the requirement with the appropriate legal, compliance, or records-management owner.
