Digital systems can replace wet-ink signatures for maintenance sign-offs in many regulated environments, but only if the solution, process, and validation evidence meet your specific contractual, regulatory, and customer requirements. You must address identity proofing, controls, audit trails, and change management, and expect mixed coexistence with paper for some time.

Digital work instructions generally provide stronger revision control than paper by enforcing a single source of truth, role-based approvals, electronic audit trails, and controlled deployment to the shop floor. Benefits depend heavily on integration with PLM/QMS, governance, and validation. Paper can still leak obsolete revisions, while digital systems make that less likely and easier to prove during audits.
