Static PDFs throttle the digital thread. This article surfaces seven hidden costs that quietly slow programs, create more human error, eat away at efficiencies, and produce unacceptable risk. It also shows a practical fix: shift to model‑based product definition (MBPD), and turn your static documents into reusable interoperable data. SWISS converts documents and drawings into machine‑readable models with clause‑level provenance and delivers them — by reference — into PLM, QMS, MES and supplier workflows. The result: faster approvals, fewer surprises at suppliers, and less rework.
