Traditional Design Process - Answers Linear Process
Requirement Phase-> Design-> realization/Prototyping -> Testing/Validation ->
Production/Implementation
-Minimal Interaction Between teams, "as needed only"
-Longer times for product optimization, larger waste
-Each department is concerned with their own responsibilities, no team collaborations
-Problems in later part of process are hard to fix
Modern Design Process - Answers Identification of need, Definition of Problem, Synthesis,
Analysis and Optimization, Evaluation, Presentation
-Many iterations throughout, not a linear process
-More communication
-Cross team interactions
-Shared responsibilities and lesser down time
-More resources along the steps, but better results during production
Design Significance: What makes a design successful? - Answers Cost vs. Functionality,
Product Sells
Design Lifetime guarantee
Load, pressure capacity
No catastrophic failure, passes rigorous testing/validation
In or under-budget
Deterioration is understood and accounted for, maintenance plan is created
