1. Identify the Problem Write a statement that answers the following questions. What are you trying to design? What are the requirement gaps? What problem is the design attempting to solve? Who are the stakeholders? Deliverable: o Three-Part Problem Definition Statement

2. Identify Criteria and Constraints Thoroughly research the problem and collect important data requirements that will determine design criteria and constraints to lead to a possible solution. Write a statement that specifies the design requirements. Information might be of more use in tabular form. Deliverables must include answers to these two questions: o What are the design limitations? (Size, weight, environment, materials, etc.) o What is the criterion or requirement that indicates a successful solution to the problem? o How will you verify (test) that you have met the criterion (requirements)?

3. Brainstorm Possible Solutions (Ideate) Conduct a group discussion using information from the previous steps to produce many possible solutions to the problem. Everyone is free to contribute and all suggestions will be recorded. Sketches are crude and quick with no proposal discounted or championed. Deliverables should include at least three of the following: o Analogy o Mind Map o Flow-Chart o Sketches o Design Notes o Test procedure or verification process

4. Develop Ideas Select two or three of the most promising ideas from Brainstorming and develop them more thoroughly. Working with pencil and rule, create new drawings that show greater detail in top, front, and side views (orthographic) as well as a dimensioned isometric view. Drawings should be neat showing parts in closer proportion than the sketches. Drawing components should be clearly labeled to include notes. Deliverables must include: o Orthographic Drawing o Isometric Drawing o Dimensions o Labels o Design Notes o Test procedure or verification process check list

5. Evaluate Possibilities Developed ideas should be shared and discussed among team members using the set of criteria and constraints identified in Step 2. Pros and Cons should be listed for each design idea and notes made on the drawings accordingly. Deliverables Should Include: o Table of Pros and Cons for Each Developed Idea o Design Notes Added To Drawings

6. Select an Approach Working as a team, come to consensus regarding the best solution to the problem. You might also consider a weighted objectives table to help facilitate a sound group decision. Do not vote. Deliverables Must Include: o Prioritized Table Of Each Solution’s Characteristics o Statement Specifying Why The Selected Approach Is The Best Solution To The Problem o Written Clarification How The Solution Meets The Criteria And Adheres To The Constraints Regarding The Identified Problem

7. Build a Model and Prototype Models can be virtual objects designed using CAD. Models can also be built using materials like cardboard, wood or Styrofoam. Many companies market modeling kits with snap-together or bolt-together parts that can be used to fabricate models of solutions to a problem. Models can be to scale or full-size. Prototypes are typically working models. This phase is used to determine problems with spatial relationships or component interaction. Deliverables Must Include: o Virtual Model o Prototype (Scale or Full-Size)

8. Test and Refine Examine and evaluate the prototype insuring its performance meets the criteria and constraints. Identify problems with the prototype’s design and brainstorm possible solutions while implementing changes until the prototype solves the problem reliably. Deliverables: o Fully Functional and Reliable Prototype

9. Documentation and Presentation Complete all the documentation necessary to construct the solution to the problem and present it to the stakeholders for review and approval. Deliverables should include the following: o Project Presentation o Gant Chart o Dimensioned CAD / CAM Design o Component Specifications o Detailed Design Notes o Component Specifications o Manufacturing / Assembly Instructions

10. Production Manufacture a full-scale fully functional solution to the design problem. Test and refine the product until it operates reliably. Deliverable: o Fully Functional and Reliable Solution o Updated and Complete Documentation
