ShareAspace is the secure, vendor-neutral backbone for multi-enterprise PLM collaboration. It acts as a neutral data integration and collaboration layer that connects PLM, CAD, ERP and asset systems, extends the digital thread across organisations, and enforces access rights, traceability and configuration change control. Built on ISO standards including STEP and PLCS, it breaks down silos while preserving governance with full auditability. Available on premises or in the cloud, ShareAspace scales from pilot to fleet and provides a through-life product repository. Core capabilities include master data management, document control for any file type, versioned parts with multi-level and cross-domain BOMs, configurable change workflows from lightweight to formal, effectivity and configuration management, data quality and maturity controls, powerful queries, task-driven work items and complete audit trails. ShareAspace integrates without exposing internal systems, respecting firewalls and separating IP between parties. Vendor-neutral mapping and import or export for common standards and formats accelerate partner onboarding and system exchange, while REST APIs simplify integration and app development. Typical use cases include design to manufacturing, supply chain collaboration across partners and contracts, export-controlled data sharing, and integrated asset information management for digital twins and lifecycle support. The result is a governed, trusted digital thread that improves decision-making, speeds clean handovers between engineering, manufacturing and operations, reduces rework, and strengthens compliance in complex, multi-stakeholder programmes.
