Know Who Is Trained, Qualified and Ready for Work
A certificate folder can show what has been uploaded, but it does not always show whether people meet the requirements for their role, project or task.

Competence Matrix FAQ
What is the difference between a training matrix and a certificate register?
A register stores evidence. A useful matrix also compares evidence against requirements, expiry dates and readiness for roles or projects.
Can DutyStack track expiring certificates?
Yes. Certificate expiry tracking is part of the competence workflow.
Can requirements be linked to roles or projects?
Yes. DutyStack supports role-based requirements and can connect competence records to project needs where configured.
Can non-login workers upload evidence?
Guest upload links can be used for evidence collection without requiring every worker to manage a full login flow.
