"Fail Early, Fail Often"

You all have heard me say this a lot lately. Don't take my word for it, here's some data from the Marshmallow Challenge:












We've done a lot of "Design-Build" challenges in our classes, should we give this one a go?

Here's a screenshot from the video that cuts to the heart of the issue. If each marshmallow from the diagram is an attempt, why is it that the Kindergartner's end result consistently outperform MBA students by more than 100%?:

Homestretch!

The Robotics Team has a midnight deadline on Tuesday to finish up their build. Good luck to all of you!

The team has been working hard these last weeks. Here are Andrew and Jackson showing me their basketball launching solution this afternoon:


Despite everyone's huge efforts, I caught the Engineering Gnome napping...


This guy is hard to catch in person. He must be wiped out from all the Engineering work!

Recursion

Iterative design is a cornerstone of the Creative Problem Solver experience. Here's a nifty video that displays the connection between iteration/recursion and the Madelbrot Fractal:




Recursion within this human constructed fractal is interesting to us because:

"Approximate fractals are easily found in nature. These objects display self-similar structure over an extended, but finite, scale range. Examples include clouds, river networks, fault lines, mountain ranges, craters,[8] snow flakes,[9] crystals,[10] lightning, cauliflower or broccoli, and systems of blood vessels and pulmonary vessels, and ocean waves" - Excerpted from Wikipedia

The idea that recursive structures occur naturally adds weight to the idea of using an iterative process in design and problem solving.

Design/Build

Jason and Joe make progress on their cardboard canoe build:


Meanwhile, Putnam and John make progress on testing a prototype:




? - Even though this team is already under way with the construction of their boat, how might the prototype support the construction of their project?
? - How effective does their model appear to be? What useful information might the team discover with their test?

Cardboard Canoe Challenge: Design Phase

This is the work we will complete for block day on Oct 4th/5th.

Sketches
• Sketch 3 solutions for your cardboard canoe design.
• Label at least 3 features on each of your sketches. Be sure to describe significance of labeled features.
• Post your sketches to your blog.

Physical Prototype
• Prototype each of your solutions using either printer paper or manila file folders and tape.
• Photograph your prototypes. Call out a key feature on each physical prototpye with a notecard or post it note.
• Post your photographs to your blog and describe any key features identified.

Design Selection
• Generate Feedback (at least one each +, change, ?, !) for each of your designs.
• Use a decision matrix to compare your 3 design approaches (we'll talk about decision matrices in class)
• Select a design approach to build. Justify your selection (reference decision matrix, feedback and any other relevant considerations).

The Deep Dive







In this activity, you will watch a group of professionals work to solve a design problem in just five days.

Copy and paste the following questions into your blog and answer them based on what you learn from watching "The Deep Dive". Use different color text for your answers to distinguish them from the questions:


1. “From the buildings in which we live and work, to the cars we drive, or the knives and forks with which we eat, everything we use was designed to create some sort of marriage between _________________ and _________________.”



2. The folks at IDEO state that they are not experts in any given area. But, they do claim to be experts on the ____________________, which they apply to the innovation of consumer products.



3. After the team of designers is brought together, told the problem, and informed they have five days to “pull it off,” what phase of the design process do they immediately engage in?







4. Give two examples of what the team members did during this phase.

a.


b.





5. List five rules-of-thumb that IDEO employees follow when they share ideas during the brainstorming phase:

a.


b.


c.


d.


e.





6. Why should wild (and sometimes crazy) ideas be entertained during the brainstorming phase?









7. After the brainstorming phase was over, the team narrowed down the hundreds of ideas by _____________ for those ideas that were not only “cool” but also _________________ in a short period of time. What phase of the design process is this called?





8. IDEO believes that the ideas and efforts of a ______________ will always be more successful than the planning of a lone genius.



9. Once the ideas were narrowed down and divided into categories, the group was split into four smaller teams. What phase(s) of the design process was each of these groups responsible for?



10. The leaders at IDEO believe that ________________ behavior and a ______________ environment are two important reasons why their employees are able to think quickly and creatively to produce innovative results.



11. Sometimes, people come up with great solutions that work by trying their ideas first, and asking for _________________ later.



12. Design is often a process of going too far and having to take a few steps back. What phase of the design process would the critique of the four mock-ups come under?





13. Upon critique of the four teams’ models, it was obvious that none of the teams had developed an optimum solution. However, the people at IDEO believe that it is important to _____________ often in order to _____________ sooner.



14. What percentage of the entire week’s time did it take to fabricate the final prototype?





15. Instead of showering his design team with a tremendous amount of praise, what did the boss require his employees to do with their new design?





16. Of all the things that we are surrounded by every day, what has not been placed through the design process?







Conclusion

1. What did you find to be the most impressive part of the team’s effort?









2. What advantages are there to having a design team with members that have non-engineering backgrounds?









3. There was a point in the process where a self-appointed group of adults stepped up, stopped the ideas, and redirected the group to break up into teams. Why was this done?









4. At the end of the video, Dave Kelly states, “Look around. The only things that are not designed are the things we find in nature.” Can you think of anything that would contradict this statement?

Rules of the Road



We've seen some extremely creative solutions to our Moustrap Racecar Challenge.

Much like our nation's tax system, there are some clever "exploits" (loopholes) available to sharp players. These aren't "wrong" for our game, just an opportunity for motivated Engineers to create a decisive advantage in the context of the current system.

Unlike our nation's bureaucracy, we have the advantage of being a lean, agile, design focused organization. We can rapidly collaborate to optimize our game design.

With an iteration of competition complete, what Criteria (rules) would you add to the Mousetrap Racecar Challenge to help "level" the playing field?

Generate a list of at least 3 ideas and be prepared to advocate at least one of them in our next class (Monday).

Emergency Preparedness!



Thursday's county wide blackout and Sunday's 10 year anniversary of September 11th are powerful reminders that large scale emergencies can happen without warning. As designers, we will consider ways that we can be better prepared for life's unexpected events. This activity serves as an opportunity to apply the PLTW 12-step design process that is part of our Engineering and Design curriculum.


Task:
Use the 12-step Design Process discussed in class to develop an Emergency Preparedness Plan. Define the problem, brainstorm solutions, create a prototype, generate user feedback and then readjust your solution.


Criteria:
Prepare a list of essential items your family would like to have on hand for an emergency situation.
You may collaborate with your classmates in developing your plan.
Each student will prepare their own list.

Constraints:
Items required for the plan/list must be affordable for your family.



Assignment: Emergency Preparedness Supply List (5pts)
Prepare and complete the following on your blog. Ensure your product is organized and professional:

Define the Problem (1pt) - What types of emergency situations might you and your family need supplies for? Include an image at the top of your post related to one of them. List at least 3 types of emergencies you want to consider for your list.

Brainstorm Ideas (1pt) - List at least 20 ideas for supplies you could use for the given emergencies (number your ideas). Get input from at least one other student (list student next to any ideas they shared). Remember the rules of brainstorming is that there are no rules.

Generate a Solution (1pt) - Given the constraints listed above, generate a list of supplies for you and your family.

Solicit Feedback (1pt) - Get specific "+, delta, ? and !" feedback from your family. List who shared what input with you.

Refine your Solution (1pt) - Adjust your plan based on your feedback. Cite a specific change based on each category of feedback (+, delta, ? and !).

4 Quadrant Feedback

When you test a prototype against a customer, you can use the following format to take notes and organize your observations:



"+" - desirable outcomes
"delta" - outcomes to change
"?" - questions raised
"light bulb" - ideas generated

Mike putting the 4 Quadrant Feedback system to use:

Glider Challenge: Test Your Prototype!



Before you're ready to "compete" with your glider, you probably want to try your design out and see how it goes. Use this 4 Quadrant format for collecting notes.

What did you learn from your test flight (post your 4 Quadrant Feedback notes for each iteration of your testing)?

What are your goals for your glider and how did you adjust your design in order to help it better meet them?
