LEAN UX: Applying Lean Principle To Improve User Experience (book summary)

I read a book by Jeff Gothelf titled “LEAN UX” which I find very helpful as a UX designer, the author outlined some of the principles of creating a product in a collaborative way with a cross-functional team based on what the user what.



Lean UX, according to Jeff Gothelf “ is the practice of bringing the nature of a product to light faster, in a collaborative, cross-functional way that reduces the emphasis on thorough documentation while increasing the focus on building a shared understanding of the product experienced being designed.

Design thinking

The concept of lean UX is built on the design thinking process because it allows the designer and the people(the team) behind the product understand what the user needs and what is not good for the products.

Communication and Collaboration

In the book the author title this foundation “Agile software development” but the reason behind this is just the team and user to be in constant communication based on research and feedback, this way large documentation behind the creation of a product is being avoided.


The author coined this phrase from the book “LEAN THE STARTUP”, this process involves the team building an MVP(minimum viable product) to test with the user and know some issue with the product so it can be iterated with the feedback, another reason for this is to validate the assumption made about the product or in some cases about the user.

Process Of Lean UX

There some methods or process behind Lean UX, this process is what makes product creation fast and user-centric. they are; Declaring an assumption, Creating an MVP, Running an experiment and feedback /research.

Declaring An Assumption

This is the first step in the process, declaring an assumption is gives us an idea about the product and user, there are ways to come about declaring an assumption.

  • Hypothesis: This is like a statement gotten from the assumption it is the” problem statement”.
  • Outcome: This is the solution we are trying to create for our product and user.
  • Persona: This is a model used to create the user of the product, this is done by understanding whom you are building the product for.
  • Feature: This is the idea behind the solution you are trying to create for your user.
  • Collaborative Design: we all think designing is only meant for the designer alone but in lean UX,design is a collaborative process that can be done together through team idea generation; where all team member comes up with ideas(sketches) of how the product will look like and creating a design system, this process speeds up the work fast and create consistency amongst team member.

Creating MVP

The goal of an MVP is to validate our assumption, there are some things to consider when creating an MVP;

  • is there value in our feature we are offering?
  • is there a need for the solution we are designing?

Feedback and Research

Research is an ongoing process in lean UX because it is broken down into smaller part so that it can fit into the ongoing process, in lean UX research is a collaborative discovery between team members and users. the author outlined somethings to look out for in research:

  • verify from other sources.
  • surveys
  • from customer care
  • Search log
  • site analysis
  • A/B testing


As a designer, entrepreneur or person working a startup lean UX is the fastest way to go about the creation of a product for the user, it is a continuous process as far as the product is still alive.

I love creating products through design.
