Pretotyping [pree-tow-tie-ping], verb: testing the initial appeal and actual usage of a potential new product by simulating its core experience with the smallest possible investment of time and money.
Alberto Savoia, author of the book, has seen that on many ideas that fail (the Wrong IT) their creators had had spend to much money and time that became harder for them to let them go, and on the other hand, the ideas that succeed (the Right IT) where less than the 20%, stated by The Law of Failure “most new its will fail - even if they are flawlessly executed”
The IT which the book refers to are thoughts we have:
· Ideas on the Table · Ideas to Test · Innovation to Try
The point of pretotyping is to find if our IT is the right thing to build. “Make sure you are building the right it before you bulid it right”
Real pretotype cases before “pretotyping” existed: · IMB speech-to-test experiment
IMB were making typewriters and computers at the time, but they find that most people found really hard type effectively. With this problem in front, they design an amazing artifact that you could speak to it and the machine would reproduce your words on the paper. To make this possible IBM needed to invest an excessively amount of money and time for research to create a 1st prototype, but before continuing with the idea they tested the product reproducing what it would do to check the customers opinions. They put a PC screen and a microphone in the room where the tester will be, and on another room would be a profesional typewriter with the keyboard and a speaker. When the tester spoke at the microphone its words appeared “magically” on the screen. After this test they saw that their product had some cons: users would end up with sore throat, it would create a noisy work environment, and was unsafe for confidencial papers.
· The Palm Pilot experiment
Jeff Hawkins had just failed recently and was determined to not fail again, so before
expending time in an expensive prototype, he make sure he had the right idea. He cut a pice of wood that fitted his shirt pocket, and draw it as how it would look when in function. He carried around the wood and pretend to used as if it was real to test if someone would use it. After answering positively to it, he begun to create the prototype and his idea became very succesful, the PDA.
Conclusion is “Fake IT before you make IT”
Pretotype helps ideas come out of THOUGHTLAND without free-falling, it’s the in between from doing nothing to make it happen, to simply go for it, instead just give it a try.
There are some techniques to pretotype:
I. The Mechanical Turk
Humans replace the functions of technology (IBM speech-to-test)
II. The Pinocchio
Only the basic structure and imagination (Palm Pilot)
III. The MPV or The Stripped Tease
“collect the maximum amount of validated learning about customers with the least effort”
IV. The Provincial
Test in a smaller part group/territory
V. The Fake Door
fake add on internet (interested people will click the link)
VI. The Pretend-To-Own
Renting before finally buying
And also there are metrics to calculate the interest I. Initial Level of Interest (ILI)
number of actions taken (actual client) / number of opportunities for action offered
(possible client)
II. OngoingLevelofInterest(OLI)
ILI with a larger amount of time of observation
