Recently I’ve learned the term "Lean UX”, which refers to a new methodology of user experience design process. It is the first time I hear this term. I looked up it through various channels on the Internet. Here are my gains.

 LeanUX is an emerging methodology that combines Agile Dev and UX. Basically, it applies Agile Dev methods into UX design and forms a process which requires quickly iterating to reduce waste. There are many differences between the traditional UX design process and leanUX. In my view, the heart of leanUX is fast and small.
 LeanUX focuses more on the outcome of a design instead of problems. The first step of LeanUX is imagining outcomes. Then designers make some assumptions according to the expecting outcome to come realize that outcome. Then analyze all assumptions to pick up ones practical. The next step is to take action to validate the assumptions. Then is making some other assumptions based on the results of previous actions to continue the next loop, make assumptions, take action, get feedback, make assumptions...

 The design by leanUX is shaped by results or data, it grows up with feedback. The method coincides with the analysis methods mentioned in the Pyramid Principle. The author of that book said that consultants in McKinsey adopt a new way to analyze more efficiently. They used to gather up all materials and then research them by order. But now, they make assumptions before research and then set off from the most relevant. If nothing was founded, they would make other assumptions and turn to other directions. The way of continuous attempts to approach the truth is very efficient and may become common in more fields.
 Besides, the data formed design reminds me of a story of Disney: When a new Disney park was going to open, the road of the park was still unfinished. The designer camp up a great idea. Pave grass everywhere instead of pavements and then pre-open the park to let tourists walk free to see which path they choose. And then, they pave according to the trails left by tourists. The process of paving is similar to leanUX: Make a raw product to test and constantly refine it according to feedback.
