A/B testing = Some users will be exposed to version A, and some to version B to identify the preferred version.
Build - measure - learn = Turn ideas into products, measure how customers respond, and then learn whether to pivot or persevere.
Eliminate uncertainty = Uncertainty is highest in the start: do (cheap and) fast experiments on the riskiest assumptions.
Eric Ries = Author of the book The lean startup
Fake door = A service that doesn’t exist (yet) but is presented in order to see if there is an interest for it
False positives = Until you present your idea for potential customers, you don’t know if it’s going to fly
Google design sprint = A way to answer critical business goals by using rapid prototyping in a week (https://designsprintkit.withgoogle.com/)
ILI = Initial Level of Interest = People invited to try innovation -> People who actually try it
Impersonator = A new design on an existing product (pretend to own / re-label). Could also be a teaser / trailer.
Innovation accounting = How to measure progress, how to set up milestones, how to prioritize work
Invision = Clickable prototypes, can also be used on phones to simulate an app
Lean UX = A book based on The lean startup, but with focus on design rather than function
Market validation = When your service/product reaches real users
Mechanical turk = A service is done manually until you know that enough people wants it
OLI = Ongoing Level of Interest = Return / retained users
One night stand = Create the impression of a whole service, but without the infrastructure needed for a permanent solution
Pinocchio = A non-functional “lifeless” version of the product as a substitute for the real one
Prototyping = Can it be done? Will it work? How shall we build it? Normally an investment of weeks/months
Pretotyping = Are people interested in this? How many customers could we get? Will customers come back? Normally an investment of hours/days/weeks
ROI = Return Of Investment = What’s the generated value compared to the investment (time/money)
Scalable = Remember that you should never keep the solution found with pre-/prototyping, it should be thrown away
Sunk cost = A cost that has already been incurred and cannot be recovered
The lean startup = Book about getting ideas validated fast, instead of investing on a dream that might never come true
Two pizza team = A term used to describe the optimal size of a team: if you can’t feed it with two pizzas, it’s too big (Jeff Bezo, founder of Amazon.com)
