Lean software development is an iterative and customer-centric approach to developing software. It aims to maximize the efficiency of the development process, minimize waste, and deliver value to customers as quickly as possible. Lean software development focuses on creating high-quality software that meets customer needs while maintaining a lean and efficient workflow.
In this guide, we will clearly define the concept of Lean development, and outline the seven Lean Principles of Lean Software Development.
What is Lean Software Development?
Lean Software Development (LSD) is an agile framework that optimizes development time and resources, eliminates waste, and ultimately delivers only what the product needs. The Lean approach is also often referred to as the Minimum Viable Product (MVP) strategy, in which a team releases a bare-minimum version of its product to the market, learns from users what they like, don’t like, and want to be added, and then iterates based on this feedback.
The roots of lean agile software development trace back to Toyota, the renowned Japanese automotive titan, which pioneered lean manufacturing principles in the 1980s. This approach focuses on efficient resource utilization, waste reduction, and delivering maximum value to customers.
In 2003, the term “lean software development” gained official recognition as Tom and Mary Poppendieck published a book of the same name incorporating its 7 principles in a clear and actionable framework.
The 7 Principles of Lean Software Development
Lean software development is based on seven fundamental principles that aim to improve efficiency, reduce waste, and enhance the overall quality of software development processes:
1. Eliminate Waste
This principle focuses on identifying and eliminating all forms of waste in the software development process. Waste refers to any activity or resource that doesn’t add value to the final product. Examples of waste include unnecessary code, redundant features, and excessive documentation. Eliminating waste helps streamline the development process and optimize resource usage.
2. Build in Quality
Instead of relying solely on testing and bug fixing, lean encourages building quality into your product from the beginning. You achieve this quality through practices like continuous integration, test-driven development, and pair programming. By addressing defects as soon as they arise in the process, teams can create more reliable and maintainable software.
3. Amplify Learning
Lean software development emphasizes the importance of knowledge sharing and learning within a team. This principle encourages cross-training, code reviews, and documentation to ensure that knowledge isn’t siloed or isolated within individual team members. Sharing knowledge improves collaboration, reduces dependencies, and enhances the team’s overall capabilities.
4. Delay Commitment
Delaying commitment involves making important decisions as late as possible in the development process. This principle allows teams to gather more information, reduce uncertainty, and adapt to changing requirements or market conditions before making decisions. By deferring commitment, teams can consistently make more informed choices, reducing the risk of costly mistakes.
5. Fast Delivery
Lean promotes rapid and incremental delivery of software. Rather than waiting for a complete, fully featured product, teams release smaller increments or iterations to gather feedback from users. This approach allows for faster validation of ideas and provides opportunities for continuous improvement based on real-world usage.
6. Respect People
This principle emphasizes the value of individuals within the development team. It encourages open communication, trust, and mutual respect among team members. By fostering a positive and collaborative work environment, teams can improve morale, foster creativity, and boost productivity.
7. Optimize the Whole
Optimizing the entire value stream involves looking at the end-to-end software development process. Instead of focusing on individual components or stages, lean encourages teams to identify bottlenecks, constraints, and areas of improvement across the entire workflow. By optimizing the whole system, teams can achieve greater efficiency and deliver more value to customers.
The Difference Between Agile and the Lean Development Methodology
The Lean development methodology and Agile are very similar. In fact, many agile work processes incorporate some lean principles. For example, achieving fast results is a central tenet of most Agile teams.
However, there are some distinct differences between these two development methods. For one, Agile focuses on the relationships between individual team members. Lean development methodology, on the other hand, looks at the team and the organization as a whole.
The Agile Manifesto states that the goal of a development team is to overcome problems and create a usable end product. While this is also a goal of Lean development, the lean philosophy emphasizes the importance of the process over the end product.
Although these two methods differ in some ways, each of these principles can add value to your work processes. The elimination of waste (Lean Six Sigma method) and group cohesion (Agile method) are positive attributes that any project can benefit from. To get the most out of them, you should use the principles of each method to shape your organization’s unique work process to get things done efficiently.
Conclusion
Lean software development is a concept that helps build the right product in the right way. It is based on seven key principles: eliminating waste, amplifying learning, deciding late, delivering fast, empowering the team, building quality in, and optimizing the whole. By following them, programmers can develop products faster and better, matching the current customer needs.
