Generate candidate solutions 5. Compare solutions and pick the winner 6. Write specification 7. Prototype, Simulate and Build 8. Test and correct 9. Implement By Third Week

2. Senior DesignSeattle Pacific UniversitySenior Design Design-2 Seattle Pacific University 1. Identify Project and Goals Find something “wrong” with the world you want to fix Automate a tedious process Help solve a resource issue Provide tools to help society Etc. Etc. Etc.

3. Senior DesignSeattle Pacific UniversitySenior Design Design-3 Seattle Pacific University 1. Identify Project and Goals Goals: Express what your project must attain to be a success Useful for comparing solutions Make sure to list all things that are important to your team Accuracy/precision Reliability Safety Efficacy Size/weight/portability Efficiency A few possible goals – add as many as needed

4. Senior DesignSeattle Pacific UniversitySenior Design Design-4 Seattle Pacific University 2. Initial Research Find out what you can about the problem you’re solving Search the web, library, etc. for: Published information Existing solutions  Advantages/Disadvantages, Cost Market research Legal/Ethical matters The more you learn now, the better your project will be

5. Senior DesignSeattle Pacific UniversitySenior Design Design-5 Seattle Pacific University 3. Brainstorm Ideas Get together in a small group and toss out ideas Start generally, then get specific No leaders! (Just a note-taker) Do not compare ideas to each other  No judgment at this time Use free-association Mandatory participation  Ask quiet members: “What do you think?” Brainstorming tool: bubbl.us

6. Senior DesignSeattle Pacific UniversitySenior Design Design-6 Seattle Pacific University 4. Generate Candidate Solutions Evaluate/combine/eliminate ideas from brainstorming (a) Form a high-level system design Include several alternative options Document each candidate solution with a block diagram and one paragraph of text Proceed to step 5 to pick winning high level design and then do sub-systems (b) Form each sub-system design Ideally, several alternative options More details than high-level design, but not intricate detail at this point Document each candidate with a block diagram and one paragraph of text

Compare Solutions/Pick the Winner A Design Matrix helps compare solutions Rows: Goals (and points available) Columns: Competing designs Entries: “Points” for that design in meeting criteria CriteriaMax Points Design 1Design 2Design 3 Cost20151018 Accuracy10683 Precision15 148 Size204 15 Reliability1510148 Customer appeal2018914 Total100687566

8. Senior DesignSeattle Pacific UniversitySenior Design Design-8 Seattle Pacific University 5. Compare Solutions/Pick the Winner First, Pick the winning high-level design Make a Design Matrix comparing the high-level design options from step 4a Most designs will have 8-10 goals at the high level Go back and develop options for each sub-system in the winning high-level design (see 4b) Pick the winning sub-system designs Make a separate design matrix for each sub-system Goals for sub-systems may be different for each one Most sub-systems will have 3-5 goals

9. Senior DesignSeattle Pacific UniversitySenior Design Design-9 Seattle Pacific University What if the design matrices point to a solution that “feels” wrong? Perhaps you didn’t include a goal you should have Maybe points were allocated incorrectly (too much/not enough emphasis in one area) Maybe the evaluation is incorrect If none of the above, then just ignore your feelings and do what the process says to do (Spock) 5. Compare Solutions/Pick the Winner

10. Senior DesignSeattle Pacific UniversitySenior Design Design-10 Seattle Pacific University What if you figure out later that your project just isn’t feasible? Talk with the instructors right away. Can switch projects in first few weeks – you’ll have to catch up, though If it really is too late, work with the instructor to modify your project to something that can work, but is still challenging. 5. Compare Solutions/Pick the Winner

11. Senior DesignSeattle Pacific UniversitySenior Design Design-11 Seattle Pacific University Must be done before beginning of next class In a small group (3-5 students) – turn in one report per group Go through stages 1-5 for a “fun” design of your choice  Don’t pick a real design – do something fun You must have at least two high level design candidates (and design matrix) – give block diagrams and one paragraph descriptions Your design must have at least two sub-systems with block diagrams and one paragraph descriptions  You do not have to find alternate designs for these – no design matrices needed for sub-systems Provide a one page summary of the final design Assignment
