Understanding “Lean Startup” in 5 minutes

There are 2 things in the world: things you know & things you do not know.

Things you do know is something like a routine. you know what to do and how to do them. Maybe you’re commuting to the office. You don’t even think about at which station to get in/get off.

On the contrary, on things you do not know you are most likely to prepare for it.
For example, when you go to somewhere new, you check in advance how to get there and how long it is going to take.

Think about going to Egypt, the Amazon rainforest, the African savanna, even go to the moon..

The little you know, the more you prepare in advance.

You make assumptions, take time to plan and identify risks in all kinds of “what if”.
Once you perfect your plan, then you take actions.

In reality this is Not going to work. This is the last thing we should do!

Making assumptions in our existing frame of mind, it is 99.9% wrong for something we have never experienced before. Even if it works by luck,it is not repeatable because you don’t know why you succeeded.

Under the extreme uncertainties, we should move quickly to test the water, experiment and learn. Yes, it takes a bit of courage but experimentation first with minimum viable product(in this case minimum viable plan) to gather feedback to understand the situation.

The Lean Startup methodology was proposed by Eric Ries in 2008.
It is a methodology for developing businesses or products by adopting a hypothesis driven experimentation, iterative product releases and validated learning in order to shorten the product development cycle.

Instead of planning and perfecting the idea/product by spending many months or even years, just market a prototype or minimum viable product and test the reactions.

It goes as follows if everything goes well.

  1. Market something you have not fully built yet in a form of MVP
  2. get pre-orders
  3. make them using the fund collected

Here is the cycle.

Build – Measure – Learn feedback loop



  1. start with “MVP”(Minimum viable product)
  2. experiment
  3. “pivot” to change or “persevere” to continue
