Design Thinking Process
5 modes iterated through
Ideation Methods
Brainstorming
Best with interdisciplinary team
Facilitating a Brainstorm Energy
Keep ideas flowing, seed questions
Constraints Add constraints that might spark new ideas Process constraints – eg lack of time
Space Create space for brainstorming
Idea Constraints What are the most obvious solutions for this problem? What can you add, remove or modify from those initial
solutions? How would a 5-year-old child solve the problem? How would you solve the problem if you had an
unlimited budget? How would you solve the problem without spending
any money? How would you solve this problem if you had control
over the laws of nature?
Selection Narrow down brainstorm list
Hang onto ideas people excited about Don’t worry about feasibility Carry forward multiple ideas into Prototyping
Techniques Post-it voting Four categories method
- Rational, delightful, darling, long shot
Bingo method - Idea that inspires
Idea Storming Idea Stormers book
Bryan Mattimore techniques Case studies Practical advice
Book Content
Seven Creative Mindsets Curiosity – always asking Why? Openness – non judgmental Embracing Ambiguity – two ideas at same time Finding and Transferring Principles – look to
other fields Search for Integrity – connecting elements Knowingness – knowing there is a solution World Creating – imaging new possibilities
The 7 Greatest Ideation Techniques Questioning assumptions Opportunity redefinition Wishing Triggered brainwalking Semantic intuition Picture prompts Worst idea
Questioning assumptions Challenge engrained beliefs/practices Process
Decide how you want to frame your creative challenge
Generate 20 or 30 assumptions you might be making about challenge
Pick several assumptions and use them as thought starters and creative triggers
Example: Mentadent (Gary Fraser) Launched in 1993 – first baking soda and
peroxide toothpaste Against Colgate and Crest
Assumptions questioned Consumers won’t pay more Consumers won’t buy refills Need to dispense toothpaste in tube Needed endorsement of dentists
Opportunity redefinition Start with opportunity statement Identify key words Generate creative alternatives for words Mix alternatives together to create
combination sentences Use combination sentences as brainstorming
triggers
Example Catholic Insurance How can we sell more insurance to Catholics? Keywords: We, Sell, Catholics We alternatives
Sales force, clergy, friends of Catholics, etc
Sell alternatives License, give away, test-run, promote, etc
Catholics alternatives Catholic doctors, Catholic schools, etc
Alternative Table We Sell Catholics Sales force License Catholic Doctors The clergy Give away Catholic Athletes Friend of Catholics Promote Catholic Students Churchgoers Advertise Catholic Schools Family members Telemarket Catholic Donators
Example: How can we get Family Members to Give Away life insurance to Catholic Schools?
Wishing Begin assuming anything is possible
Money, energy, time, etc are unlimited
Generate 20 – 30 wishes Use wishes as creative stimuli to generate
novel but realistic ideas Consider wishing from different perspectives
Role-playing wishing, target market wishing
Triggered Brainwalking Paste a piece of paper on the wall for each
person in the group – use trigger terms Each person goes to a piece of paper and
writes down an initial idea Then rotate to the next paper, builds on the
existing idea or uses it to stimulate new idea Keep on going for several rounds until back to
beginning and person can select best ideas
Example: Lipstick Product
Triggered with four prompts Target market wishes Category reframes (lip reshaping, lip firming, etc) Benefit-oriented: lip massaging, freshening, etc The worst idea technique
Benefits
Physical engagement Ideas are public, shared ideation People inspired by other ideas
Semantic Intuition Combine several categories of key words to
create a name for a new idea Process
Create 3 categories of words related to challenge Generate variations in each category Randomly combine one word from each category Brainstorm around result
Example: Detergent Promotion Places in Store Promotions Benefits/Interests Aisle Gift with purchase Clean clothes
Parking Lot Buy one get one free Getting stains out
Bakery Floor stands Fresh smelling
Frozen Foods Redeemable Coupon Family dinners
Pharmacy Register Coupon Baseball games
Flower Shop Shelf talkers Disney world
Trigger: Bakery, Gift with Purchase, and Clean Clothes
Idea: Cookies + Detergent promotion. Buy detergent and get free cookie dough mixture. Eat a cookie while doing washing and enjoy the smell of clean clothes and fresh baking
Picture Prompts Select pictures related to problem Pass out picture prompts Ask for ideas inspired by the visuals Share thoughts with partner and brainstorm
together “Imagine the answer is contained in one of these pictures. See if you can find it?”
Improved Delegation
Worst Idea Create list of worst ideas Keep going to generate worse and worse ideas Use list of bad ideas to inspire a good idea
Eg: Banking services We could round down everyone’s deposits Bank of America “Keep the Change”
TRIZ – Formalized Problem Solving ‘Teoriya Resheniya Izobreatatelskikh Zadatch’
Theory of Inventive Problem Solving
Developed by Genrich Altshuller (1940’s) Working in Soviet Navy patent dept. Analyzed over 200,000 patents Developed innovation theory
Most Problems Already Solved
Altshuller screened over 200,000 patents Over 90% problems has been solved before
Levels of Inventiveness, Level 4 and 5 truly innovative
Levels of Solution Level #1 are simple improvement of a technical system using
knowledge available within a relevant industry. Level #2 inventions include the resolution of a technical
contradiction using knowledge from different areas Level #3 is an invention containing a resolution of a physical
contradiction using knowledge from other industries. Level #4 is development a new technology. It is developed
by using breakthrough solutions that requires knowledge from different fields of science.
Level #5 involves the discovery of new phenomena that pushes the existing technology to a higher level.
Key Findings Problems and solutions are repeated across industries
and sciences. By classifying the "contradictions” in each problem, you
can predict good creative solutions to that problem. Patterns of technical evolution tend to be repeated
across industries and sciences. Creative innovations often use scientific effects outside
the field where they were developed.
Example: Drink Can Stacking Want to stack drink cans for storage
We have no control over how high cans will be stacked
Contradiction Can walls should be thinner to reduce costs Can walls should be thicker to support weight
Types of Contradictions Eliminate contradictions to solve problems Two types of contradictions
Technical – classic engineering trade-offs. - The product gets stronger (good), but the weight increases (bad). - Training is comprehensive (good), but keeps employees away from
their assignments (bad).
Physical – inherent contradictions (laws of physics) - Coffee should be hot for enjoyable drinking, but cold to prevent
burning the customer. - Training should take a long time (to be thorough), but not take
any time.
General Problem Solving Model
Applying TRIZ process 1. Identify my problem 2. Formulate the problem
Identify contradictions
3. Search for previously solved problem Using TRIZ tools
4. Look for analogous solution and adapt to my solution
Key TRIZ Tools Engineering Parameters (Formulate problem)
39 standard technical characteristics that cause conflict
Inventive Principles (Previous Solutions) 40 solution hints that will guide towards an
innovative solution
Engineering Parameters 1. Weight of moving object 2. Weight of nonmoving object 3. Length of moving object 4. Length of nonmoving object 5. Area of moving object 6. Area of nonmoving object 7. Volume of moving object 8. Volume of nonmoving object 9. Speed 10. Force 11. Tension, pressure
11. Shape 12. Stability of object 13. Strength 14. Durability of moving object 15. Durability of nonmoving object 16. Temperature 17. Brightness 18. Energy spent by moving object 19. Energy spent by nonmoving
object 20. Power
Inventive Principles 1. Segmentation
Divide an object into independent parts Make an object sectional
14. Spheroidality Use rollers, balls spirals Replace linear parts or flat surfaces with curved ones
35. Transformation of physical and chemical states Change an object's aggregate state
Table of Contradictions
Table of Contradictions
Example: Can Stacking Principle 1: Increase Segmentation
Change wall from smooth to wavy
Principle 14: Spheroidality Use curved can tops
Principle 35: Transformation Use stronger alloy composition
Example - Segmentation
Divide an object into independent parts or make sectional Problem: Long antennas are necessary for radio transmission but can
be broken when the car goes into a low-clearance garage Solution: Construct antenna from cylindrical metal beads strung on a
wire. When the beads are loosened they can be compactly stored. When the wire is tightened, the beads form a long, flexible antenna.
Example - Inversion Doing something opposite to what is currently being done. Problem: Cattle are usually branded using
hot irons - - a painful procedure that causes wounds prone to infection.
Solution: Irons cooled to liquid-nitrogen temperature can be used. These irons do not wound the animals, but instead permanently discolor the hair at the branding spot.
Example – Prior Action
Performing a required action beforehand or prior placement of an object so that it can be used without delay. Problem: Cattle feed consists of various cut grasses which are
mixed using special equipment. Producing the grass mixture by sowing the various grasses together yields a crop difficult to till.
Solution: If the grasses are sown in narrow parallel strips and harvested across the strips, they will be mixed in the receiving bin of the harvester.
Assignment Five ASSIGNMENT 1. Try applying one or more of the three innovation principles of Segmentation, Inversion and Prior Action to the following: Problem 1. Removing layers of insulation Certain metallic surfaces must be coated with a thick layer of insulating material. Removing this coating later is difficult, however. How might this be accomplished?
Problem 2. Unloading frozen material Unloading loose, frozen material by first defrosting it can be an expensive procedure. What other method would you recommend?
Problem 3. Bullet-proof windows Initially, bullet-proof glass windows used on fighter aircraft had a serious defect: When a bullet hit the window, a "network" of cracks would form in the glass and obstruct the pilot’s vision. How might this damage be reduced?
