Lean Engineering

"The only way to win is to learn faster than anyone else." - Eric Ries


Lean thinking has been around for a while, originating in manufacturing, but it can be applied to any industry, including software engineering. Lean thinking is a methodology that focuses on maximizing customer value while minimizing waste. It is all about creating more value for customers with fewer resources.

Adopting lean engineering practices can streamline your processes, reduce risk, and improve customer satisfaction. By adopting lean principles, you can streamline your team's processes, eliminate waste, and continuously improve engineering practices.

Lean Engineering

Lean engineering is a systematic approach that aims to create maximum value for customers by reducing waste in the process.

This methodology strongly emphasizes continuous improvement, close collaboration among team members, and actively seeking customer feedback. What sets lean engineering apart is its emphasis on experimentation and data-driven decision-making. This approach allows you to quickly and effectively test ideas and continually improve their offerings. The ultimate goal is to deliver top-notch products that perfectly align with customer requirements and expectations.

To achieve this, lean engineering follows a set of key principles.

  1. Customer Value: First and foremost, lean engineering is identifying the value customers seek and ensuring that every activity in the engineering process directly contributes to that value. It focuses on mapping the value stream, which means carefully analyzing and optimizing all the steps in delivering the final product. This helps to identify any unnecessary processes or bottlenecks that can be eliminated or improved.

  2. Less is More: One of the core principles of lean thinking is to eliminate waste, and this includes eliminating anything that is not necessary. In software development, this means deleting code, features, or processes that do not contribute to the end goal. Often, companies fall into the trap of believing that more is better. They try to include all the possible features, thinking it will make their product more valuable. What often happens is that the product becomes bloated and confusing, making it harder for customers to use and decreasing its overall value.

  3. Flow: Another important principle of lean engineering is creating flow, which means streamlining the workflow and minimizing interruptions or delays. This enables a smooth and efficient production process, enhancing productivity and reducing lead time. Additionally, lean engineering emphasizes establishing pull, which involves producing only what is needed based on customer demand. This helps to avoid overproduction and reduce unnecessary inventory, ultimately leading to cost savings.

  4. Experimentation: This involves creating small, incremental improvements and testing them with a select group of users. By doing so, companies can quickly determine if their ideas are worth pursuing and make changes as needed. This approach also allows for user feedback, which can provide valuable insights into what works and what doesn't. The end result is a product that meets the needs and wants of the users, rather than one based on assumptions.

  5. Agile: This involves creating small teams that work collaboratively to produce a working product. These teams are empowered to make decisions and have the flexibility to change direction when needed. Agile development is all about creating a culture of experimentation, learning, and improvement. The result is a team that is highly responsive to customer needs and can quickly produce high-quality products.

  6. Excellence: The pursuit of excellence is what drives lean engineering. This means constantly striving for excellence and never settling for mediocrity. It involves setting high standards, monitoring performance, and continuously seeking ways to improve and optimize the engineering process.

Lean engineering is a methodology that emphasizes efficiency, waste reduction, and continuous improvement. By adopting poor engineering practices, teams can reduce the time it takes to bring a product to market and improve customer satisfaction.

  1. Waste: Waste includes physical waste, such as excess inventory or unused materials, and wasted time and effort. Teams can work more efficiently and effectively by streamlining processes and eliminating unnecessary steps. Reducing waste also helps to minimize costs and increase resource utilization.

  2. Speed: By focusing on the most critical features and delivering them quickly, teams can get their product in front of customers sooner and start generating revenue. Speed is essential to staying ahead of competitors and seizing market opportunities.

  3. Risk: This reduces the risk of building a product that nobody wants or needs and allows teams to focus on delivering value to customers as quickly as possible. By carefully managing risks, teams can make informed decisions and avoid costly mistakes.

  4. Customer: By delivering a high-quality product that meets their needs and expectations, teams can build a loyal customer base and increase their chances of success. Prioritizing customer satisfaction leads to positive word-of-mouth, repeat business, and long-term growth.

The lean product approach has revolutionized how startups, scale-ups, and prominent companies approach product development. This approach is all about experimentation and getting fast feedback from customers. By focusing on creating the minimum viable, you can test ideas quickly and efficiently without wasting valuable time and resources, validate assumptions, and make informed decisions about further development.

"The Lean Startup teaches you how to drive a startup: how to steer when to turn, and when to persevere." - Eric Ries

According to a study by McKinsey & Company, companies that adopt lean engineering practices can reduce their time to market by up to 50%, reducing costs and improving quality. Additionally, by involving customers early in the development process and using MVPs to test assumptions, teams can ensure they build products that meet customer needs and expectations.

Minimum Viable Product

Minimum Viable Product (MVP) is at the heart of lean engineering. It is a product version with just enough features to satisfy early customers and provide feedback for future development. MVPs are essential in lean engineering because they allow teams to validate assumptions, reduce risk, and deliver customer value faster.

To create a successful MVP, it's essential to focus on the core features that provide the most value to your customers. This means prioritizing functionality over aesthetics and avoiding feature creep. By keeping your MVP simple and focused, you can get it to market quickly and start gathering feedback immediately.

"The lesson of the MVP is that any additional work beyond what was required to start learning is waste, no matter how important it might have seemed at the time." - Eric Ries

Best Practice

Define: Before starting any project, defining the problem you are trying to solve is essential. This involves identifying the pain points of your target audience and understanding their needs and wants. Limiting the situation ensures that your solution addresses the correct issues and delivers value to your customers.

Validate: MVPs are an excellent way to test your assumptions and validate your ideas before investing too much time and resources into a project. By creating a minimum viable product, you can gather feedback from your target audience and make informed decisions about the direction of your project.

Measure: Gather feedback from customers: Customer feedback is crucial for the success of any project. By listening to your customers and incorporating their input into your product, you can ensure that you deliver value and meet their needs. Use surveys, interviews, and other feedback mechanisms to gather customer insights.

Iterate: The lean engineering process is iterative, so you should constantly refine and improve your product based on customer feedback. Use data and analytics to track your product's performance and identify improvement areas. Continuously iterate on your product to deliver more value to your customers.


Several tools and resources can greatly assist teams in effectively implementing lean engineering and MVPs.

Lean Canvas: One highly regarded tool is Lean Canvas, a concise one-page business plan that empowers teams to define crucial elements such as the problem they are addressing, their target customers, the proposed solution, their unique value proposition, and more.
