PLM Essentials

5. Engineering Structures

Adam Tonks16 July 2021

Engineering structures are how product data gets organised, referenced, and released. Get them right and the BoM, change management, manufacturing handover and aftermarket all benefit quietly in the background. Get them wrong and every subsequent process pays a friction tax. The fifth instalment of QR_'s PLM Essentials series covers the structural choices that determine how well a PLM environment actually works in practice.

What you'll learn

Inside this guide

  • Why structures shape everything downstream. How structural decisions made early cascade into BoM navigation, change impact analysis, and manufacturing handover — often long after the people who made the decisions have moved on.

  • EBOM, MBOM, SBOM and the transitions between them. When each view matters, how they relate, and the mechanisms that keep them aligned without descending into manual duplication and reconciliation.

  • Structuring for variants and change. Designing the hierarchy so that variants and revisions are absorbed cleanly rather than fracturing the structure over time into unmaintainable branches.

  • Aligning with organisational capability. Matching structural ambition to the PLM platform, team capability, and process maturity actually available today — rather than the one an ideal white paper assumes.

PLM Essentials

The complete series

Nine focused guides covering the foundations of effective product data management. Each part tackles a specific discipline — from part numbering and attributes through to configuration management and process development. Written by practitioners, grounded in two decades of hands-on programme delivery across automotive, aerospace, defence, and energy.
