Systems thinking is a powerful approach that goes beyond traditional linear problem-solving methods in software development. In a recent conversation with Diana Montalion, author of “Learning Systems Thinking: Essential Non-Linear Skills and Practices for Software Professionals,” we explored how this mindset can transform the way we build and maintain software systems.
Traditional software development often focuses on linear, procedural thinking - writing code in a top-down, controlled manner. While this approach has its place, systems thinking introduces a complementary perspective that considers how relationships between components produce effects that neither could achieve alone.
Systems thinking examines how different parts of a system - whether code, people, or processes - interact and influence each other. Rather than just focusing on individual components, it considers the broader context and impact. For example, instead of merely evaluating how a piece of code performs in isolation, systems thinking considers how it affects the overall system’s behavior, user experience, and business value.
The core of systems thinking is understanding that relationships between parts often matter more than the individual parts themselves. This applies to both technical relationships (like API interactions) and human relationships within development teams.
While traditional approaches emphasize control and predictability, systems thinking focuses on achieving meaningful impact. This means considering how technical decisions affect the broader system and its stakeholders.
Systems thinking helps identify leverage points - places where small changes can have significant impacts. This is often more valuable than making numerous small changes without considering their systemic effects.
One simple but powerful practice from improvisational comedy is the “Yes, and …” technique. Instead of immediately critizing or disagreeing, acknowledge what others contribute before adding your own perspective. This builds better communication and collaboration within teams.
When proposing solutions, share not just what should be done, but why it matters and how you reached that conclusion. Include:
ADRs become more powerful when they include:
While systems thinking might initially seem to add complexity, it actually helps reduce cognitive load over time by:
Systems thinking helps teams:
Starting with systems thinking doesn’t require a complete transformation. Begin with small practices:
Systems thinking isn’t about adding more complexity to software development - it’s about having better tools to handle the complexity that already exists. While it requires some initial investment to learn and practice, the benefits in terms of better decision-making, improved collaboration, and more effective problem-solving make it well worth the effort.
As software systems continue to grow in complexity, the ability to think systemically becomes increasingly valuable. By adding these tools to our professional toolkit, we can better understand and influence the systems we work with, leading to better outcomes for both technical systems and the people who build and use them.
Remember: You don’t have to think about everything all the time - systems thinking is just another tool in your toolbox, ready to be used when needed to solve complex problems more effectively.
