Configure a Review Matrix

The review matrix eliminates manual reviewer assignment for routine documents. Once configured, Workflows automatically determines the correct reviewer(s) for every document based on its attributes — discipline, document type, zone, and package. This tutorial walks a project admin through building, testing, and activating a review matrix from scratch.
Role: Project Admin or Org Admin
Prerequisite: Project has documents configured with at least one discipline and document type.
Why use a review matrix?
Without a review matrix, a document controller must manually assign a reviewer to every step of every workflow. On projects with hundreds of documents across multiple disciplines, this creates:
- Assignment errors (wrong reviewer selected)
- Delays when document controllers are unsure who is responsible
- Re-work when organisational structure changes
The review matrix centralises responsibility assignments so they are maintained by the admin, applied automatically, and auditable.
Step 1 — Navigate to the review matrix
- Go to Settings → Review Matrix (project-level settings).
- The review matrix shows a list of existing rules (empty on a new project).
- At the top, a summary shows how many rules are configured and whether there is a fallback rule.
Step 2 — Understand rule structure
Each rule in the review matrix consists of:
| Field | Description |
|---|---|
| Rule name | A descriptive label for the rule (e.g., Civil Drawings – Structural Lead). |
| Match conditions | One or more filters that must all match for the rule to apply. Conditions can be: Discipline, Document Type, Zone, Package, Confidentiality. |
| Assignee | The user, project role, or access group to assign when the rule matches. |
| Step type | The step type this rule applies to: Review, Approve, Acknowledge, Sign. |
| Approval mode | For multi-assignee rules: Any One (any one team member), All Required (all must respond), Majority. |
| SLA hours | Override the default step duration for documents matching this rule. |
| Priority | Determines which rule wins when multiple rules match the same document. Lower numbers = higher priority. |
Step 3 — Add your first rule
- Click Add Rule.
- Enter a Rule Name (e.g.,
Structural Drawings – Technical Review). - Set Match Conditions:
- Click Add Condition.
- Select the field: Discipline = Structural.
- Add a second condition: Document Type = Drawing.
- Set the Step Type: Review.
- Set the Assignee: select an access group (e.g.,
Structural Review Group). - Set Approval Mode: Any One (any member of the group can respond).
- Set SLA hours: 120 (5 business days).
- Click Save Rule.
Step 4 — Add discipline-specific rules
Repeat Step 3 for each discipline + document type combination in your project. Common patterns:
| Rule name | Conditions | Assignee | SLA |
|---|---|---|---|
| Civil Drawings – Technical Review | Discipline=Civil, Type=Drawing | Civil Lead | 5 days |
| Mechanical Specs – Engineering Review | Discipline=Mech, Type=Specification | Mech Engineer | 5 days |
| All Drawings – PM Approval | Type=Drawing | Project Manager | 2 days |
| Method Statements – HS Review | Type=Method Statement | H&S Manager | 3 days |
Step 5 — Add a fallback rule
A fallback rule matches any document that no other rule matches. Without a fallback, documents outside your explicit rules would require manual assignment.
- Click Add Rule.
- Name it
Default Reviewer – Fallback. - Leave all conditions empty (matches everything).
- Set the Assignee to a senior document controller or project manager.
- Set Priority to a high number (e.g., 99) so it is evaluated last.
- Save.
Step 6 — Set rule priority
When a document matches multiple rules:
- The rule with the lowest priority number wins.
- Rules with equal priority that match the same step type are both applied (multi-reviewer parallel step).
To reorder rules:
- Click and drag rules in the list, or
- Edit each rule and change its Priority value manually.
Step 7 — Test the matrix with a sample document
Before activating the matrix for all workflows:
- Open the document register.
- Find a test document with known discipline, type, and zone.
- Click Actions → Start Workflow and select a template with Review Matrix as the step assignee.
- In the workflow start panel, observe the auto-assigned reviewer for each step.
- Verify the assignments match your expectations.
- If an assignment is wrong, cancel the workflow start (do not submit) and update the relevant rule.
Step 8 — Test edge cases
Test at least one document for each of these scenarios:
- A document matching the fallback rule only (no specific rule applies)
- A document matching two competing rules (check priority resolution)
- A document with Confidential flag (if confidentiality rules are configured)
- A document with an unusual combination (e.g., zone-specific rule)
Step 9 — Update workflow templates to use Review Matrix
For each template step that should use the matrix:
- Open Settings → Workflow Templates → [Template].
- Edit the relevant step.
- Change the Assignee from a named user or role to Review Matrix.
- Save the template.
Now every workflow started from this template will trigger the review matrix to determine the correct assignee.
Maintaining the matrix
- When team membership changes, update the access group membership rather than the matrix rules.
- When project scope changes (new disciplines, new zones), add new rules before the first document of that type is uploaded.
- Review the matrix quarterly using the Review Response Summary report — look for patterns where rules are matching unintended reviewers.
- Archive rules that are no longer needed (they remain in history but are not evaluated).
