Managing complex component data in machine building projects doesn’t have to be a logistical nightmare. For manufacturing operations leveraging CRA-compliant software, an inefficient bill of materials process can lead to costly errors, production delays, and compliance headaches. The difference between struggling with scattered component information and having a streamlined, efficient system often comes down to a few strategic improvements.
Today’s machine builders face mounting pressure to maintain complete documentation while accelerating production timelines. With the right approach to structuring your software BOM, you can transform this challenging aspect of operations into a competitive advantage.
In this guide, we’ll explore practical solutions that will help you optimize your machine builder software documentation, reduce errors, and ensure compliance with evolving regulatory frameworks like the CRA.
Understanding the challenges of bill of materials management in CRA machine builder software
Machine builders frequently encounter significant obstacles when managing their software bill of materials, especially under the new Cyber Resilience Act requirements. Maintaining accurate component records across multiple systems and project phases creates substantial friction in development workflows. When component data becomes inconsistent, it triggers a cascade of issues including procurement delays, assembly errors, and compliance risks.
The most common pain points include version control breakdowns, where teams struggle to identify which component versions are incorporated in specific machine builds. This leads to troubleshooting difficulties and potential security vulnerabilities when outdated components remain undocumented. Additionally, disconnected data silos between engineering, procurement, and production teams mean valuable information gets lost in translation, requiring time-consuming manual reconciliation.
For machine builders implementing low-code solutions, these challenges are particularly acute as they must track both hardware and software components within the same project scope. The CRA requirements add another layer of complexity, demanding complete transparency and traceability for all digital elements within industrial systems.

Step 1: Audit your current BOM structure and identify bottlenecks
Before implementing improvements, you need a clear picture of your existing bill of materials management system. Begin by documenting your current BOM creation and maintenance processes from initial design through production and service. Map how component information flows between departments, identifying where handoffs occur and which tools are used at each stage.
Look for signs of inefficiency such as duplicate data entry, manual spreadsheet manipulation, or frequent revision conflicts. These are key indicators of process bottlenecks that need addressing. Pay particular attention to how software components are documented in your CRA implementation – are firmware versions, libraries, and dependencies clearly tracked alongside hardware components?
During your audit, gather feedback from cross-functional team members about their pain points when working with your current BOM structure. Engineering might struggle with revision control, while procurement teams may face challenges with component sourcing due to incomplete specifications. Understanding these perspectives helps prioritize improvements that deliver the most significant impact.
After completing your assessment, create a prioritized list of specific bottlenecks that are costing your team the most time or creating the highest risk of errors. This becomes your roadmap for targeted improvements.
Step 2: Implement standardized component naming conventions
Inconsistent naming creates massive headaches when managing machine components across projects. Establish clear, company-wide conventions for identifying and describing each component in your bill of materials. This standardization forms the foundation for all subsequent BOM improvements in your machine builder software environment.
Your naming protocol should include specific fields like component type, manufacturer identifier, functional category, and version information. For example, instead of simply listing “controller,” use a structured format like “CTRL-SIEMENS-S7-1500-V2.1” that conveys comprehensive information at a glance. This structure makes components instantly recognizable and searchable across your entire system.
When implementing these conventions, remember to address both hardware and software components with equal rigor. Under CRA requirements, digital elements require the same careful documentation as physical parts. Ensure your naming system accommodates firmware versions, software libraries, and third-party dependencies that may impact security compliance.
Consistency is essential for success. Create a reference guide documenting your naming standards and conduct training sessions to ensure adoption across departments. The initial investment in standardization pays dividends through reduced errors and improved cross-team communication.
Step 3: Utilize hierarchical BOM structures for complex assemblies
Complex machinery requires sophisticated documentation approaches. Implementing a multi-level hierarchical structure allows you to organize components into logical assemblies and subassemblies, creating clear parent-child relationships that mirror your actual machine architecture. This approach transforms overwhelming component lists into manageable, intuitive structures.
Start by identifying major functional units within your machine designs, then break these down into progressively smaller subassemblies. Each level should represent a meaningful grouping that can be assembled and tested as a cohesive unit. This organization simplifies maintenance, troubleshooting, and component updating throughout the machine lifecycle.
For machine builders implementing CRA-compliant software, hierarchical structures provide essential visibility into how software components interact with physical systems. You can clearly document which software elements control specific machine functions, making security assessments and updates more straightforward. This level of organization is particularly valuable when conducting compliance reviews or responding to regulatory requirements.
Step 4: Integrate your BOM with procurement and inventory systems
Disconnected systems create unnecessary friction in your operations. By connecting your bill of materials directly with procurement and inventory management platforms, you create a seamless flow of component information throughout your organization. This integration eliminates duplicate data entry and provides real-time visibility into component availability.
Modern low-code platforms make this integration increasingly accessible, even for organizations with limited IT resources. Look for opportunities to connect your engineering tools with enterprise systems through standard APIs or middleware solutions. These connections allow procurement teams to access up-to-date component specifications directly from the source, reducing errors and expediting ordering processes.
With integrated systems, you can implement automated alerts for long-lead items, potential supply chain disruptions, or component obsolescence issues. This proactive approach prevents production delays and allows for strategic inventory management based on accurate usage forecasts derived from your BOM data.

Step 5: Establish regular BOM review and optimization protocols
Even the best-designed BOM system requires ongoing maintenance and improvement. Implement a structured review cycle where cross-functional teams evaluate BOM accuracy, completeness, and efficiency on a regular schedule. These reviews should examine both process adherence and opportunities for systemic improvement.
Your review protocol should include verification that all components (particularly software elements) are properly documented with current version information. This is especially critical for CRA compliance, where outdated components may introduce security vulnerabilities. Regular audits help identify potential compliance gaps before they become serious issues.
Use each review cycle as an opportunity to identify commonly used component assemblies that could be standardized across multiple machine designs. This standardization reduces engineering overhead and simplifies inventory management while ensuring consistent quality and performance.
Finally, document lessons learned and best practices discovered during your improvement journey. Creating a knowledge base around effective BOM management preserves institutional knowledge and accelerates onboarding for new team members.
