Julian Weyer
Making complex products manageable — through PLM, ALM, and a continuous Digital Thread.
Senior Consultant at PROSTEP/BHC. My approach: understand first, then design.
Who is Julian
variantmanagement.com is the personal project of Julian Weyer — a consultant at PROSTEP/BHC specializing in PLM, ALM, and variant management for complex, software-driven products. His clients include manufacturers of automotive systems, automation components, industrial equipment, and medical devices working through the challenges of increasing product complexity.
What sets Julian apart: he knows PLM from both sides of the table. Before moving into consulting, he held roles in product marketing, sales, and order engineering — which means he has lived with the consequences of processes that don't match reality. When the first question in a project is "which system?", something is usually already wrong.
His methodology — first understand, then design — means starting with the actual problem, not the tool, and building solutions that stay efficient and maintainable over time. The goal is always a clear, continuous Digital Thread: from requirements through development, production, and the product in the field.
