BP4 Ensure consistency and establish bidirectional traceability. ( O3 )

1. Ensure consistency (Consistency = Consistency addresses content and semantics and ensures that Information items are not in contradiction to each other.
Consistency is supported by bidirectional traceability.

See also chapter D.3.) and establish bidirectional traceability (Traceability = Traceability refers to the existence of references or links between Information items.
Traceability supports coverage analysis, impact analysis, requirements implementation status tracking etc.

See also chapter D.3.) between the Mechanical Component Sample Production Specification (Mechanical Component Sample Production Specification = Mechanical Component Sample Production Specification includes, e.g.:

• process design
• vertical range of manufacture
• manufacturing equipment
• structure and logistics of manufacturing
• make or buy decision
• production process parameters (e.g., pressure, rates, calibration data, etc.)

) and the Mechanical Component (Component = Components (physical or virtual) are the lowest level elements of the mechanical architecture for which the component design is further defined.) Design.
2. Establish bidirectional traceability (Traceability = Traceability refers to the existence of references or links between Information items.
Traceability supports coverage analysis, impact analysis, requirements implementation status tracking etc.

See also chapter D.3.) between the recorded Production (Production = Production is defined as component manufacturing or system assembly or the combination of both.) Data and the Mechanical Component Sample Production Specification (Mechanical Component Sample Production Specification = Mechanical Component Sample Production Specification includes, e.g.:

• process design
• vertical range of manufacture
• manufacturing equipment
• structure and logistics of manufacturing
• make or buy decision
• production process parameters (e.g., pressure, rates, calibration data, etc.)

).
3. Establish bidirectional traceability (Traceability = Traceability refers to the existence of references or links between Information items.
Traceability supports coverage analysis, impact analysis, requirements implementation status tracking etc.

See also chapter D.3.) between the produced Mechanical Component (Component = Components (physical or virtual) are the lowest level elements of the mechanical architecture for which the component design is further defined.) Samples and the recorded Production (Production = Production is defined as component manufacturing or system assembly or the combination of both.) Data.

Note 4: Bidirectional traceability (Traceability = Traceability refers to the existence of references or links between Information items.
Traceability supports coverage analysis, impact analysis, requirements implementation status tracking etc.

See also chapter D.3.) supports consistency (Consistency = Consistency addresses content and semantics and ensures that Information items are not in contradiction to each other.
Consistency is supported by bidirectional traceability.

See also chapter D.3.), and facilitates impact analyses of change requests, and demonstration of verification (Verification = Verification is confirmation through the provision of objective evidence that an element fulfils the specified requirements.) coverage (Coverage = There are:

• all objects
  
• relevant objects
  
• mapped objects

Coverage is a measure used to describe the ratio of mapped objects to relevant objects for a specific purpose.

For instance:

• Requirements coverage: ratio of mapped system requirements versus relevant system requirements
  
• Dimensional test coverage: ratio of tested dimensions versus total numbers of dimensions
  
• Elements test coverage: degree of tested elements versus all created elements
  
• Verification coverage for critical characteristics: ratio of tested or verified (e.g. production process capability – CpK) critical characteristics based on control plan

arrow_forward "Consistency vs. Traceability – What’s the Difference?"

person Author: Process Fellows
Consistency ensures that related content doesn’t contradict itself – e.g., requirements align with architecture and test. Traceability, in contrast, is about links: can you follow a requirement through to implementation and verification? Both are needed – consistency builds trust, traceability enables control. Typically, traceability strongly supports consistency review.

arrow_forward "The role of traceability in risk control"

person Author: Process Fellows
Traceability isn’t just about completeness — it’s about managing impact. When a requirement changes, trace links tell you what’s affected. That’s your early-warning system.

arrow_forward "The true benefit of traceability "

person Author: Process Fellows
Sometimes the creation of traceability is seen as an additional expense, the benefits are not recognized. Traceability should be set up at the same time as the derived elements are created. Both work products are open in front of us and the creation of the trace often only takes a few moments. In the aftermath, the effort increases noticeably and the risk of gaps is high. If the traceability is complete and consistent, the discovery of dependencies is unbeatably fast and reliable compared to searching for dependencies at a later stage, when there may also be time pressure. It also enables proof of complete coverage of the derived elements and allows the complete consistency check.
