Comparison Table
HAZOP+
enterpriseHAZOP study software from Isograph for hazard and operability analysis with customizable node and deviation tracking.
Reusable study templates and configurable report layouts support consistent project records across recurring HAZOP work.
HAZOP+ provides configurable study templates, classification scales, libraries, and report layouts. Attached drawings and supporting documents keep design context with each record. Its structured data model reduces duplicated entries when teams review related findings across a project.

- +Linked records keep causes, consequences, safeguards, and recommendations connected.
- +Configurable libraries reduce repeated entry across similar studies.
- +Risk ranking matrix supports consistent consequence and likelihood classification.
- +Generates formatted reports from structured study data.
- –Desktop-centered deployment limits browser access for distributed workshop teams.
- –Public documentation does not emphasize API-driven automation.
- –Advanced cross-study governance may require local administration and conventions.
- –Visual process-diagram authoring is not its central workflow.

How to Choose the Right Hazop Software
We see options separate on how safely and consistently teams capture HAZOP study details and drive follow-through. The biggest split shows up in recommendation tracking, so actions don’t get lost between worksheets, meetings, and approvals.
Study workflow coverage
Why it matters
Study workflow coverage matters because hazop software has to handle the real path from plan to review without breaking the link between nodes, sessions, and outcomes. If the workflow is shallow, teams end up reworking files and losing decision context.
How to check
Ask for a walkthrough that starts with creating a study and ends with closing it. In the demo, change a session status and confirm the UI and exports reflect the same step states and timestamps.
Recommendation tracking and status
Why it matters
Recommendation tracking and status is what keeps hazards from becoming paperwork. When statuses, owners, and due dates stay attached to the right outcomes, audits and revalidation become far less painful.
How to check
Pick one sample outcome and create two recommendations with different due dates and assignees. Then filter by status and export to verify the linkage stays intact even after you edit the recommendation text.
Audit log for edits
Why it matters
Audit log for edits matters because hazop software is used to justify decisions. If changes aren’t traceable, teams can’t confidently answer who changed what during a study cycle.
How to check
Edit a key field on an existing session outcome and refresh the record. Show an audit view (or equivalent history) that lists the field, old vs new values, user, and time.
Worksheet roundtrip import/export
Why it matters
Worksheet roundtrip import/export matters when teams must bring in legacy content. If import mangles structure or export formats don’t match what reviewers expect, teams lose throughput on cleanups and reformatting.
How to check
Request a sample file set that mirrors how studies are currently stored. Import it, then verify key relationships (session to node to outcomes) and export it back; compare that the edited items map to the same places.
Node and outcome data model
Why it matters
A consistent data model prevents the same node or outcome from being represented differently across sessions. With hazop software, that consistency affects filtering, reporting, and the ability to rerun analyses later.
How to check
In the demo, create two nodes and link multiple outcomes to each. Then reassign one outcome to a different node and confirm reports and relationships update without duplicates or orphaned links.
RBAC and governance controls
Why it matters
RBAC and governance controls matter because hazop work often spans engineers, reviewers, and approvers. If permissions are too coarse, the process stalls or people bypass intended checks.
How to check
Ask the admin to set at least three roles (creator, reviewer, approver) and restrict editing of completed content. Attempt edits as each role and confirm what changes are blocked and what audit entries still appear.
Red flags
- Edits don’t show who changed what and when
- Recommendations lose ownership or due dates during export
- Node-to-outcome links break after import or reassignment
Fit by situation
- If your team runs multiple sessions per study and needs consistent closure, prioritize Study workflow coverage.
- If you already track follow-ups outside the tool, prioritize Recommendation tracking and status.
- If you need traceability for reviewers after edits, prioritize Audit log for edits.
