When it comes to problem solving, engineers are fearless because they follow these rules. 1. K.I.S.S. Keep it simple, stupid! Forget the frills and the cheap thrills. Focus on the heart of the matter. 2. Identify. 3. Reduce. 4. Learn. 5. Design. 6. Source. 7. Optimize. 8. Test. 9. Iterate. 10. Amplify.
