Below the Surface

Your quality department is costing you millions. Not because they're doing a bad job-because they're fighting fires you could have prevented.

After two decades managing quality in aerospace and defense manufacturing, Chad Diggs watched the same pattern repeat: quality leaders get blamed for problems they didn't have authority to prevent. Engineering cuts design reviews. Procurement picks cheaper suppliers. Production skips verification. Then when the product fails? "Why didn't Quality catch it?"

This is the delegation trap.

Below the Surface follows Kristina Valdez, a quality manager at Aegis Aviation, as she breaks this trap by building prevention systems that outlast tenure. Through her story, you'll discover why most organizations measure only 10% of their true quality costs-and the frameworks that transform quality from firefighting to strategic capability.

Calculate the hidden costs (Chapters 1-2): The engineering firefighting, production delays, and expedited shipping that never appear on COPQ reports. Operationalize the 1:10:100 Rule: spending $1 on prevention beats spending $100 on field failures.

Break the delegation trap (Chapters 3-6): Embed quality into every function's decision-making. Plan quality into products (not inspect it out). Design for the real customer ecosystem. Build stop-the-line culture where people speak up without fear.

Manage your extended factory (Chapters 7-8): Risk-based supplier segmentation, capability qualification, and CAPA systems that actually learn from failures.

Create competitive advantage (Chapters 9-11): Position quality as strategic moat. Design governance that survives leadership changes. Build systems that outlast individuals-because heroes burn out, but systems compound.

• Quality managers tired of firefighting
• Operations leaders who know prevention is cheaper
• Plant managers building systems that outlast tenure
• Engineers designing quality in from the start
• Anyone in manufacturing who's been blamed for problems they didn't have authority to prevent

Not another quality handbook. A practitioner's blueprint from aerospace and defense where mistakes are costly and prevention isn't optional.

Not theory. Every framework includes manufacturer data, decision models, and templates you can use Monday morning.

Not hero worship. Kristina is fictional but authentic-representing every quality leader who had to build systems without unlimited budgets.

Honest positioning. COPQ calculators, supplier segmentation, DFMEA, CAPA governance-proven methodologies adapted for mid-market manufacturers.

• The Iceberg: COPQ model with hidden cost calculation
• The 1:10:100 Rule: Prevention prioritization
• The Delegation Trap: Quality embedded across functions
• Planning Quality In: APQP, DFMEA, PFMEA integration
• Stop-the-Line Culture: Psychological safety
• Supplier Segmentation: Risk-based qualification
• Learning from Failure: CAPA that prevents recurrence
• Quality as Moat: Prevention as competitive advantage
• Systems That Last: Governance surviving leadership change
