1. Life Science, Engineering, Design Enschede Project 2: DoE Outline project www.saxion.nl/led

2. Course Design of Experiments at Saxion • Introduction-DOE in Feb 2014 • Project ‘Catapult’ Feb - July 2014 • Groups of 4/5 students with supervisor Sniekers • Payment: 3 EC • Weekly introduction lecture • Feedback session at fixed time every 2 weeks • Assessment day in June ‘Proof of Quality by presentation, demonstration and report

3. Benefit for you • You gain some • knowledge, • comprehension, • awareness, • expertise • in te field of Six Sigma and in the method of Design of Experiments in particular. It’s a opportunity to make a special mark on your engineering-degree, which could be decisive for a lot of employers.

4. Course Design of Experiments at HTW • 1 week Introduction-DOE in April 2014 by Sniekers • Project ‘Catapult’ April - July 2014 • Groups of 4 students with supervisor HTW • Payment: 3 EC • Weekly feedback session at fixed time (Skype) • Assessment days in July ‘Proof of Quality by presentation, demonstration and report • Later more!

5. The Project • Customer requirements: Sniekers • Process: Catapult, Trebuchet, ……….. • Goal: Hitting target with tennis balls over a distance (LSL, USL) (9,5 and 10,5 m ) • Design and build a catapult (example is available) • Gauge R&R and Design of Experiment • Find the vital factors en their optimal setting • Delivery: shooting 10 tennis balls; 2 series of 5 shots • Measure: distance (X), deviation (Y), • Determine: number of hits and defects, variance

6. Example project Catapult • DOE with 5 Factors • Bal position • Spring right • Spring left • Buffer pin • Rotation axis

7. Example 2013

8. Delivery in June Which team has the best performance??? USL LSL Catapult Y • Shoot 10 tennis balls in 2 series of 5 shots • Determine: • Number of hits (defects) • Average value of X and Y: • Standard deviation in X and Y: sx, sy X

9. Schedule ‘DOE-project’ • February: register for project in groups of 4 students • February - March: Start-up • Weekly 1hour theoretical introduction • Design and build Catapult or Trebuchet, or … • Approval!! • Select Gauge and perform Gauge R&R • April– June: DOE • Design Experiment and perform tests • Evaluate test results and determine optimal settings • July: Delivery • Review (deliver report, presentation) • Demonstrate quality Project team • Evaluation and discharge project • Individual reflection (STARR)

10. Project Review July • Students Saxion and HTW Saarbrucken • Date and location not known yet • Project Deliverables (group): • Demonstration Catapult • Poster presentation (A3) • Power-Point Presentation (max 15 min) and evaluation • Report containing, design catapult, design experiments, data, choices and arguments, data-processing, • Individual deliverables: • Individual reflection (STARR) • Peer-evaluation

11. Peer evaluation: Valuable feedback from your fellow students • Scale:: • 0 = normal; • + = better than normal; • ++ = much better than normal; • = worse than normal; • - = much worse than normal • Including short motivation • Aspects of feedback: • Presence • Cooperation • Contribution • Communication • Reliability (fulfilling tasks, promises) • Responsibility • Willingness to learn

12. Individual reflection: STARR-method • Describe during and afterwards the project your own part/ contribution / learning targets with the aid of the STARR-method • S = Situation: describe the situation as concrete and precise as possible • T = Tasks: What were your tasks / parts in the project (concrete and precise)? • A = Actions and Activities: What actions and activities did you do to contribute in the project (again, concrete and precise)? How did you do that (strategy)? What problems did you come across? • R = Results: What were the concrete results of your work? • R = Reflection: How did the project go? What did you learn (knowledge, abilities)? What will you do different/the same next time? What did you come beware of and what did you learn about yourself? What feedback did you receive?

13. Situation • What was the situation? • What happened? • Who were involved? • Where took it place? • When took it place? • Reflection • What are the knowledge and skills you’ve learned? • What will you do different/the same next time? • What did you learn about yourself? • What feedback did you receive • About what issues were you satisfied? • What do you still have to learn? • What do you need for this? • Task • project: • What was your task / part? • What role did you have? • What was expected of you? • Personal: • What did you want to accomplish? • What did you expect of yourself in this project? • What did you think you should do? STARR • Results • What were the results of your work? • How did your contribution fit in the total picture • How is your work appreciated? • Action & Activities • What did you exactly do in this project? • What ideas did you bring in? • What problems came across? • What was your strategy?
