Last position:
Platform Architect & Senior Developer at Direct client, industrial measurement technology, medium-sized company
- Technical leadership across hardware, firmware, and software teams; scope: hardware/firmware team (4 people) and leadership group (5 people)
- Consolidated and documented a product family that had grown over more than 15 years and aligned it with CRA compliance — from the bare-metal I/O module to the cloud interface.

About the technology
Product structure
A Bill of Materials, commonly called a BOM, is the structured list of parts, materials, components and assemblies required to make a product. It can describe a simple finished item or a complex product with multiple levels, variants and production stages. Accurate BOM data links product design with purchasing, manufacturing, service and cost control.
BOM formats
Companies use engineering BOMs to represent design intent and manufacturing BOMs to define how a product is assembled. Service BOMs support maintenance, spare parts and field repairs, while configurable BOMs manage product options. Strong structures include quantities, units, revisions, approved alternatives, effectivity dates and links to source documents.
Ecosystem and tooling
BOM work often spans CAD and PDM systems, PLM platforms, ERP software and manufacturing execution systems. Specialists understand data models, part numbering, classification, change workflows and integrations between these systems. They may also work with spreadsheets, APIs, import templates and reporting tools when legacy data must be cleaned or migrated.
Typical deliverables
- Create or restructure multi-level engineering and manufacturing BOMs
- Reconcile CAD, PLM and ERP product data
- Define revision, release and engineering change processes
- Prepare configurable BOMs for product variants
- Document service parts, substitutes and assembly relationships
When expertise matters
Companies bring in freelance BOM specialists during ERP or PLM implementations, product launches, acquisitions and data migrations. They are also valuable when production teams find inconsistent part numbers, missing relationships, duplicate components or unclear revision ownership. In German manufacturing, automotive, industrial equipment and electronics environments, they can support remote analysis with on-site workshops where needed.
What strong specialists bring
Strong professionals combine product data discipline with a practical understanding of design, procurement and manufacturing. They ask how a component is released, sourced, assembled, changed and serviced before defining the structure. Quality shows in traceable revisions, clear ownership, validated quantities, useful documentation and reliable handoffs across teams. They communicate clearly in the language and systems used by the project.
Frequently asked questions
Quick answers to the questions that come up most around Bill of Materials.
A Bill of Materials defines the parts, materials, quantities and relationships needed to produce, assemble or service a product. Companies use BOMs for planning, procurement, production control, costing, compliance and after-sales support.
A BOM is a controlled product structure that adds context such as quantities, revisions, effectivity and assembly relationships. A parts list may be a simpler view, while a product structure can describe design relationships without containing all manufacturing or service information.
A strong Bill of Materials specialist often understands CAD, PDM, PLM, ERP and manufacturing execution workflows. Useful adjacent skills include data migration, part-number governance, engineering change control, configuration management and SQL or API-based integration.
The right level depends on the scope and risk of the product data. A straightforward cleanup may need focused process and system knowledge, while a multi-site migration or configurable product model calls for experience across engineering, purchasing, manufacturing and service.
Yes, much Bill of Materials work can be completed remotely through controlled system access, workshops and documented review cycles. On-site sessions can still help with production observations, stakeholder alignment and access to restricted engineering or manufacturing environments.
A BOM specialist should be comfortable with the systems used by the client, such as PLM, PDM, ERP, CAD and manufacturing platforms. Tool knowledge matters, but understanding data ownership, release states, integrations and change processes matters just as much.
Review whether the Bill of Materials is complete, traceable and usable by every relevant team. Check quantities, units, revisions, alternates, effectivity and links to source records, then validate the structure against real assembly, purchasing and service scenarios.
Before working with a BOM, professionals should clarify the source systems, target system, product variants, revision rules and required deliverables. They should also confirm data ownership, approval gates, access constraints, language expectations and how success will be validated.
