Introduction / Context:
Working drawings communicate the official definition of a product for manufacturing and inspection. Because they define scope, requirements, and acceptance criteria, they carry legal weight in contracts, purchase orders, and supplier agreements. The statement that they are not legal documents is therefore false.
Given Data / Assumptions:
- Drawings are controlled under document management and revision procedures.
- They are referenced in procurement and quality records.
- They may be stamped or approved per regulatory requirements.
Concept / Approach:
In disputes over conformance, the released drawing set (or model-based definition) is the authoritative reference. Acceptance tests, inspection plans, and certificates of conformance trace back to drawing requirements, making the drawing part of the legal framework between buyer and seller.
Step-by-Step Solution:
Release drawings through a formal engineering change process.Reference drawing numbers and revisions on POs and inspection records.Maintain a revision history that documents changes and approvals.Ensure that suppliers acknowledge the drawing as the product definition in contracts.
Verification / Alternative check:
Review typical supply agreements; they cite the drawing set as part of the contract deliverables.
Why Other Options Are Wrong:
Correct: Asserting that drawings are not legal documents is inaccurate; they commonly are.True only if stamped by a PE / Applies only to government contracts: While stamps and specific regulations may add formality, drawings often have legal force in private-sector contracts as well.
Common Pitfalls:
Using uncontrolled drawings, which weakens traceability and legal clarity.Failing to update downstream documents when drawings are revised.
Final Answer:
Incorrect
