< General Engineering Introduction | CDIO

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.)

The process for single, platform and derivative products

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

Appropriate techniques, tools, and processes

Design tool calibration and validation

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)

Performance, life cycle cost and value

Aesthetics and human factors

Implementation, verification, test and environmental sustainability

Operations

Maintainability, reliability, and safety

Robustness, evolution, product improvement and retirement
