The Hidden Cost of Mismanaging Engineering Calculations

• Engineering calculations represent computational modeling – Designing to meet product, customer, and standards requirements – Testing, predicting & understanding the behavior of systems – Example: analyze a braking system to calculate the maximum hydraulic pressure expected in the brake lines
• Two kinds of modeling: – Applied mathematics – a conceptual explanation of the system expressed in custom mathematics
• Gives a limited experience, but expands & codifies understanding – Virtual prototyping – 3D CAD drawings and simulations of systems
• Cheaper & faster than physical build & test
• Yields experience with the system, but little formal insight into assumptions, methods and calculations
