“Lean UX” implies that less UX is being done. !
That couldn’t be further from the truth, nor is it something we should encourage.

It is NOT Anti-‐deliverable It is a refocusing of UX efforts away from the documentation and moves towards validating product hypotheses

It is NOT design-‐by-‐committee Who needs vision when you have meetings?

You don’t need “The Spec” to keep control You are in the problem-‐solving business, and you don’t solve problems with design documentation.

The Value of the Minimum Viable Product The bare feature set needed to prove out a hypothesis

Started with a boring 3 minute video in 2008 for their minimum viable product, beta waiHng list jump from
5,000 to 75,000 in one day (Mar 2008)
Started in 1984 with a single Boeing 747 flying a single route (Gatwick to Newark and back). As they got the Virgin magic
working and debugged, they added more planes and more routes.
Examples of Minimum Viable Product (MVP)
It started out as a simple WordPress blog, the point.com with a widget that used AppleScript to
send PDFs coupons via Mail.app
Same principle is applicable for the larger, growing Mirms too!
You probably won’t fancy the 1st version of Facebook, but it started to address user needs first

Story 3

hFp://www.kickerstudio.com/blog/images/ux.jpgSource: Ar*cle from Jared M. Spool, Nov 30, 2011, Is There Any Meat on This Lean UX Thing?
Lean UX is just UX. But UX isn't always Lean UX.
2. Features begin as hypotheses to be tested before heavy investment
3. A feature starts as a minimum valuable feature, and then iterates
4. Proof carries more weight than opinion
5. The team talks to real customers on a regular basis, including in-person
1. You are composed of small, goal-driven, cross-functional teams
How Lean UX may work well?
How Lean UX may not work well?
1. If your stakeholders requires formality to justify decisions
2. If you need to deal with legacy systems and require regular updates
