What is lean methodology in software development?

Lean methodology in software development represents a transformative approach that prioritizes delivering value to the end-user with the utmost efficiency. Originating from the principles of Japanese manufacturing, especially the Toyota Production System, this methodology has been skillfully adapted to the realm of software development. At its heart, Lean is about streamlining production by rigorously cutting out any activities that don’t add value, thereby enhancing efficiency. It’s a philosophy that intertwines the quality of the final product with the process of its creation, embedding testing and feedback loops into every stage to ensure that the end result not only meets but exceeds user expectations.

As Lean methodology has evolved, it has transcended its manufacturing origins and taken a firm hold in the software industry. Lean methodology in software development has been reinterpreted to address the unique challenges of digital product development. By focusing on reducing cycle times, Lean methodology in software development encourages a faster turnaround, enabling quicker delivery of software products to market. This shift is not just about adopting new techniques; it’s a fundamental change in mindset. Software development teams are now embracing Lean’s core principles to refine their workflows, eliminate redundancies, and deliver high-quality software more efficiently than ever before.

Lean software development principles

The transition from traditional software development models to Lean methodology in software development represents a significant shift in the industry. Traditional models often emphasize detailed planning and extensive documentation, which can lead to rigidity and waste. In contrast, Lean in software development promotes adaptability and waste reduction.

The core lean software development principles are not just guidelines but the very pillars upon which the methodology stands, each one contributing to a system that is both efficient and value-driven.

Eliminate Waste is the principle that targets the heart of inefficiency. With Lean methodology in software development, waste is defined as any activity that consumes resources but creates no value for the customer. This could manifest as excess code that complicates maintenance without improving functionality, or meetings that consume time without contributing to progress. By streamlining processes, teams can focus on what truly matters, ensuring that every task and piece of code serves a direct purpose. This not only speeds up the development process but also results in a cleaner, more maintainable codebase.

Amplify Learning is about fostering an environment where continuous improvement is part of the culture. In the fast-paced world of software development, technologies and customer preferences evolve rapidly. Teams that prioritize learning can stay ahead of the curve, adapting to new tools and methodologies that enhance their capabilities. This principle goes beyond formal training; it’s about creating a feedback-rich environment where knowledge is shared freely, mistakes are seen as learning opportunities, and every project contributes to the collective expertise of the team.

Decide as Late as Possible is one of the lean software development principles that might seem counterintuitive at first glance, but it’s about maintaining the flexibility to make informed decisions. In traditional project management, decisions are often made early to set a clear direction. However, Lean methodology in software development posits that early decisions can lead to early mistakes. By deferring commitment until the last responsible moment, teams can leverage the most current and complete information available. This adaptability is particularly valuable in a landscape where client needs and market dynamics can shift unexpectedly. It allows teams to pivot and adapt their products, ensuring they deliver solutions that are truly aligned with user needs.

Together, these lean software development principles form a robust framework for teams aiming to improve their workflow and output continuously. They are not static rules but dynamic forces that drive the Lean approach to software development, ensuring that the end products are not only built more efficiently but also hold greater value for the users they’re designed to serve.

When poorly structured custom software development projects fail to deliver results, Lean takes undeserved blame.

It’s easy to blame project failures or deficiencies on Lean methodology in software development. However, it is more likely that there are inherent flaws in the application of Lean which have a greater bearing on outcomes. Whether yours is a financial or legal firm, a construction or contracting business, a non-profit, or a consumer services business such as retail, a lack of time, organizational commitment, conceptual honesty, structure and investment are just some of the factors that can derail Lean projects. In the end, wasting an opportunity to seriously leverage the value of a well-structured Lean project is a hallmark of failed initiatives.

The biggest misunderstanding of lean methodology

The purpose of Lean is to enable proof of a concept’s market value prior to major investment. The assumption at the very heart of Lean is that at least some elements of the concept’s core value proposition will be conveyed correctly to the market in the initial Lean Minimal Viable Product (MVP) release. The misunderstanding by most entrepreneurs and corporate product owners is that Lean means “cheap test.” This couldn’t be further from the truth. Lean actually means “the least expensive test that is a valid test.”

Common reasons of project failure happen when “Leaners” skimp on:

  • User experience: A poorly designed user experience can compromise the basic adoptability characteristics and may yield false negatives.

  • Incomplete value proposition: If there is not a cohesive set of features that is worth the users’ time, it doesn’t matter if you have a few features beautifully built. So if users won’t come or they won’t stay, it’s not because the concept is bad, it’s because the concept was not actually realized for them.

  • Adaptation to change: Team members who are entrenched in traditional development methodologies may initially be skeptical or resistant to the new approach. This resistance can stem from a discomfort with the unfamiliar or a belief that existing processes are sufficient.

  • Maintaining the software’s quality: While adhering to Lean’s waste elimination tenet. The drive to cut out unnecessary processes must be carefully balanced against the risk of inadvertently stripping away elements that contribute to the product’s quality. If you have a beautiful user experience and a feature set that conveys concept value, but the software is flawed, users will distrust the software and ultimately the parent company, and abandon the product. Ensuring that quality remains uncompromised while streamlining processes is a delicate act that requires vigilance and a deep understanding of what truly adds value to the end product.

Notice that none of the scenarios above disprove the business concept. They are false negatives created by poor execution within Lean methodology in software development.

Making the most of Lean projects for custom software development

Define your Lean MVP as a product that is ready to reliably show off your concept in a compelling way to its intended audience. Make sure it includes intelligent user experience and design, provides value to your potential users and has gone through strict quality control before users are exposed to it.

Be prepared to spend money. A shortsighted cost reduction strategy can starve any Lean project regardless of its veracity.

For a more accurate application of Lean methodology in software development, you must commit to:

Delivering as fast as possible: Accelerate time-to-market by streamlining the development cycle, thus providing quicker feedback loops and the ability to pivot when necessary.

Empowering the team: Give autonomy to the development team, allowing those closest to the work to make decisions, which often leads to better outcomes and more innovative solutions.

Building integrity: Focus on creating a coherent and well-functioning software system that delivers value to the customer, emphasizing the importance of software integrity.

Seeing the whole picture: Avoid sub-optimization by ensuring that the development process is optimized for the entire system, not just individual components.

Applying these tenets will result in a fair proof of concept, ideas for further product development, and savings vs. a full launch. What you won’t get is a feeling that Lean methodology in software development equals “cheap.” This is what valid Lean looks like.
