Verification, Validation, and Independent Check
Run independent checks, quantify differences and close out every discrepancy before submission.
Verification vs. validation
Verification — "are we solving the equations right?"
An independent reviewer repeats the calculation using a different method (hand calc, closed-form solution, alternate software) and confirms the numbers agree within an acceptable tolerance. This catches input errors, unit errors and modeling mistakes — not wrong assumptions.
Validation — "are we solving the right equations?"
Confirms the governing equations, load path, boundary conditions and failure mode actually represent the real structure and its real behavior. A perfectly verified model of the wrong problem is still wrong.
Every governing result on this project should carry both: (1) an independent hand check using a different method than the primary analysis, and (2) an order-of-magnitude sanity check (does the number feel right compared to a simple envelope estimate?).

Design warnings (1)
- No independent verification records yet — every governing calculation needs a hand check.
Learning objectives
- Perform independent checks
- Quantify percent difference
- Close discrepancies
Engineering judgment
- The checker must not repeat the designer's method.
- Differences above 10% need explanation.
