The Design Process
Requirements for each element or component derived from system level goals and requirements
Alternatives in design
The initial design
Experiment prototypes and test articles in design development
Appropriate optimization in the presence of constraints
Iteration until convergence
The final design
Accommodation of changing requirements
The Design Process Phasing and Approaches
The activities in the phases of system design (e.g. conceptual, preliminary, and detailed design)
Process models appropriate for particular development projects (waterfall, spiral, concurrent, etc.)
Utilization of Knowledge in Design
Technical and scientific knowledge
Creative and critical thinking, and problem solving
Prior work in the field, standardization and reuse of designs (including reverse engineer and redesign)
Design knowledge capture
Disciplinary Design
Quantitative analysis of alternatives
Modeling, simulation and test
Analytical refinement of the design
Multidisciplinary Design
Interactions between disciplines
Dissimilar conventions and assumptions
Differences in the maturity of disciplinary models
Multidisciplinary design environments
Multidisciplinary design
Multi-Objective Design (DFX)
Aesthetics and human factors
Implementation, verification, test and environmental sustainability
Operations
Maintainability, reliability, and safety
Robustness, evolution, product improvement and retirement
