1. 1 Welcome The Design Process Engineering Design

2. 2 Today’s Learning Outcomes By the completion of today's meeting, students should be able to: Prescribe the design process. Identify the elements of each design process. Express the relation between various blocks of the design process.

3. 3 Prescriptive Design Process A Prescriptive Design Process that outlines the steps necessary to progress through a design. Therefore, a basic understanding of the Problem Definition is required for any design.

4. 4 Prescriptive Design Process Each stage has Inputs, has Design Steps that have to be performed, and produces Outputs (or product). Outputs from one stage become the Inputs for the next stage.

5. 5 Problem Definition

6. 6 Sources of information The sources of information for P.D. : current technical literature, codes, regulations, experts, … etc. Design methods: objectives tree, pairwise comparison chart, … etc. Means: literature review, brainstorming, user surveys, questionnaires, interviews,..

7. 7 Conceptual Design

8. 8 Sources of Information Competitive products: additional sources of information for conceptual design, … Design methods: functional analysis, function-means trees, quality function deployment morphological charts, requirement matrices, performance specifications,... etc. Means: brainstorming, synergy, reverse engineering (dissection), benchmarking, analogies,... etc.

9. 9 Preliminary Design

10. 10 Sources of Information Preliminary design sources of info: heuristics (rules of thumb), simple models, physical relationships,... etc. Design methods: physical modeling, experimental verification,... etc. Means: numerical modeling & simulation, prototype development, lab & field testing, proof-of-concept testing,... etc.

11. 11 Prescriptive

12. 12 Sources of Information Perspectives sources of info: laws & regulations, design codes, handbooks, component specifications,... etc. Design methods: CADD,... etc. Means: formal design reviews, public hearings, beta testing,... etc.

13. 13 Communication

14. 14 Sources of Information Design communication sources of information: feedback from clients and users, itemized lists of required deliverables, … etc.
