Controlled documents that actually stay controlled.

Document control under ISO means a documented procedure approves, distributes and obsoletes documents, and proves it. A shared drive or email thread can't demonstrate that. ENSURE keeps a version label on every document, marks old versions clearly superseded but still readable, and tracks a review date so you know when each document is next due: the control a shared folder can't show at audit.

The module is built for ISO 9001 / 45001 / 14001 document control (SOPs, procedures, policies and work instructions) without needing a separate document-management system. Versioning, review dates and expiry alerts come out of the box, and the audits that check a document link straight back to it clause by clause. That is the documented, provable control those standards require.

Every revision keeps its version label, and old versions stay readable but are clearly marked superseded, so a current effective document sits alongside its archived predecessors rather than overwriting them. This is the versioning that survives audits, where a reviewer needs to see what was in force and when, not just the current file.

Each document tracks a review date and next-review date, and expiry alerts fire before those review dates lapse. You also get site and department visibility scoping, so the right people see the documents that apply to them. The review clock is on the record itself rather than in someone's calendar.
