Lean Startup is a disciplined, scientific and capital efficient method for discovering and building products and services that people love.

It rocks.

It rocks far more than Agile.

Here’s a table to illustrate some differences (sorry for not defining each term, I’ll leave that as an exercise for you):

Agile	Lean Startup
Product Roadmap	Business Model Canvas
Product Vision	Product Market Fit
Release Plan	Minimal Viable Product
Sprint	Kanban
Sprint Review	Pivot or Persevere Decision
On-Site Customer	"Get Out Of The Building"
User Story	Hypothesis
Backlog	"To Learn" List
Definition of Done	Validated Learning
Red-Green-Refactor	Build-Measure-Learn
Customer Feedback	Customer Validation
Acceptance Test	Split Test
Velocity	AARRR
Mock Object	Feature Fake
Continuous Integration	Continuous Deployment
Certified Scrum Master	Customer Success Manager

Lean Startup makes the best parts of Agile more lean and combines them with the brilliant Customer Development process.

I suggest that you start learning about Lean Startup right away and go buy Eric’s book.
