“The Lean Startup” by Eric Ries is a highly influential book that has changed how entrepreneurs approach the startup world.

This book’s main idea is to revolutionize how companies approach value and growth hypothesis discovery and validation. The aim is to turn a company’s vision into a feasible business model through a scientifically rigorous method.

To achieve this, the Lean Startup methodology focuses on creating a minimum viable product and gathering customer feedback to enhance it. Publishing a preliminary version of a functioning product often reveals valuable insights and ideas that would have gone unnoticed otherwise. It enables a more personalized final product.

By embracing a scientific approach to business management, Lean Startups experience faster delivery of products to customers and growth acceleration. The Lean Startup process teaches a systematic approach to innovation, guiding companies to adapt, evolve and persist for maximum business expansion.

Let’s dive in a little deeper!!!

“The Lean Startup: A Different Approach to Entrepreneurship” 

Lean Startups’ embody a philosophy and a method for streamlining processes, avoiding waste, and efficiently transforming ideas into successful products and businesses. Its central tenet is the Build-Measure-Learn cycle, where customer feedback and testing drive continuous improvement and informed decision-making.

Building a Culture of Innovation with the Lean Startup Methodology?

Startups are distinctive entities that stand out from the rest, characterized by their elevated level of risk. The reason behind this is their innovative approach to problem-solving.

In response to his failed attempts at launching a startup, Eric Ries penned “The Lean Startup” to help companies reduce their risk through implementing MVP, systematic experimentation, regular feedback collection, adaptive problem-solving ability, and a continuous drive for improvement.

The Lean Startup method embodies creating a successful business with maximum efficiency without wasting unnecessary time and resources.

MVP Definition

The Minimum Viable Product, or put, the “minimum working product,” embodies minimalism with functionality. It strives to fulfill customer demands with the bare minimum and gather crucial customer feedback to refine the offering.

With customer satisfaction as the ultimate goal, feedback allows companies to decipher what works and what doesn’t, enabling them to navigate toward creating unparalleled value.

The 5 Principles of the Lean Startup Method

Eric Ries established five principles of the Lean Startup method. These are the foundations he built his theory, and I relate them below.

Entrepreneurs are Everywhere: The spirit of entrepreneurship knows no bounds. It transcends backgrounds and fields, fueling the drive and ambition of individuals from all walks of life to turn their ideas into realities.

Validated Learning: The key to success for entrepreneurs lies in validating their assumptions through ongoing experimentation and learning. By embracing a trial-and-error approach, they gain invaluable insights and are better equipped to chart their course to success.

Innovation Accounting: Metrics and experiments are indispensable tools for measuring progress and success in entrepreneurship. By embracing innovation accounting, entrepreneurs are empowered to track their progress and make informed decisions.

Build-Measure-Learn: At the heart of the Lean Startup methodology lies the “build-measure-learn” feedback loop, an iterative process that drives continuous improvement and fuels success.

Flow: A successful startup prioritizes creating a steady flow of customer value. By focusing on the needs and wants of their customers, entrepreneurs can build businesses that survive and thrive.”

“The problem with entrepreneurship is that we often work too hard to produce high-quality products that nobody wants.”

Eric Ries

Lean Startup: How it Works

The operation of the Lean Startup method is a continuous cycle composed of the construction, measurement, and learning phase, or the so-called build-measure-learn cycle (build-measure-learn).

Lean Startup Canvas

The Lean Startup Canvas is a redefinition of the canvas by Ash Maurya.

The differences between the original Canvas business template and this one are:

  • Partners / Problem: we must establish the three priority problems we intend to solve instead of partners.
  • Key Activities/Solution: One needs to understand solutions to established problems instead of activities.
  • Features/Metrics: After that, you must identify the metrics to establish whether the business model is validated.
  • Customer Relationship / Unfair Advantage: finding a competitive advantage over competitors.
  • Value Proposition / Unique Value Proposition: What is the one reason why a customer should prefer you? What sets you apart?

In conclusion, the Lean Model Canvas focuses on the problem and the solution because they are considered more important than the partners. In addition, the UVP (Unique Value Proposition) is also fundamental, as it is better to focus little but at the beginning.
