What is Balanced Coupling?
Balanced Coupling is an innovative framework for modular software design. Built on over 50 years of software engineering insights, it distills proven principles and techniques into a concise, easy-to-use guide for making software design decisions.
You might be wondering—do we really need yet another software design tool? Software engineering is hard. To be successful, you need to learn design patterns, architectural styles, engineering principles, and countless other “best practices”—so why invent yet another?

It Shouldn’t Be This Hard
It Shouldn’t Be This Hard
Throughout my career, I’ve always believed that it should be easy to do the right thing. Ironically, more often than not, the most important things are the hardest to get right. This is especially true in software design. Good module boundaries should be evident—not something you have to fight for. Renaming a module shouldn’t break half the system, and adding a feature shouldn’t feel like defusing a bomb.
From Struggle to Structure
These were exactly the kinds of situations I found myself in when I was leading a failed microservices-based project. Trying to understand why something that seemed to work so well for industry superstars had gone so wrong for us led me to revisit the concept of coupling—and the various models used to evaluate it. I eventually understood why the project had failed, but I also discovered how difficult it is to apply models and methodologies coined half a century ago to modern software systems.
That’s how the model of Balanced Coupling came to life.

I’m Vlad Khononov, and I created the Balanced Coupling model to bridge the gap between classic software design theory and the messy, fast-paced reality of modern systems. Balanced Coupling doesn’t just adapt classic coupling models to fit today’s engineering practices—it brings them together into a cohesive tool for making design decisions. It helps you evaluate whether a choice you’re about to make will lead to greater modularity or deeper complexity. And it’s pragmatic, too: it highlights the areas of your system that need the most attention, helping you focus your efforts where they’ll have the biggest impact.
Getting Started
Most importantly, Balanced Coupling is simple. You don’t need to study a stack of books or accumulate years of experience. All it takes is one formula and an understanding of three key dimensions of coupling. This website will give you the core concepts to get started. If you want to go deeper, Balancing Coupling in Software Design explores the ideas in full detail, with examples, case studies, and practical guidance.
