Section 13 of 50
11. Product, Process, Resource and Evidence Separation
Stable section ID: S05-CON-012-SECTION-13 · 46 content blocks
System05 shall distinguish Product, Process, Resource, and Evidence as separate but related manufacturing domains.
The Product domain shall define what is being produced, including:
- Product identity.
- version.
- geometry.
- material.
- function.
- Interfaces.
- critical characteristics.
- acceptance requirements.
The Process domain shall define how production is performed, including:
- Operations.
- sequence.
- process parameters.
- setup requirements.
- intermediate states.
- hold points.
- rework paths.
- inspection points.
The Resource domain shall define what is required to execute the process, including:
- Machines.
- tools.
- fixtures.
- gauges.
- software.
- personnel.
- robots.
- utilities.
- environmental conditions.
- facility capabilities.
The Evidence domain shall define what demonstrates that the required product and process conditions were achieved, including:
- Material certificates.
- machine records.
- measurements.
- inspection results.
- images.
- sensor data.
- operator approvals.
- test results.
- calibration status.
- release records.
- These domains shall not be silently collapsed.
Use of the correct machine shall not prove that the correct product was produced. Completion of the correct process shall not prove that all acceptance criteria were satisfied. A complete evidence package shall not compensate for falsified or nonrepresentative physical production.
Relationships among the domains shall be explicit. A process shall identify the product versions it supports, the resources it requires, and the evidence it must generate.
Changes in any domain shall trigger evaluation of effects on the others.
Evidence shall be sufficient to support the required decision without creating unnecessary cost, surveillance, or data burden. The quantity and reliability of evidence shall be proportional to criticality, process capability, novelty, and uncertainty.
