If you've ever felt like your business is constantly reacting to a random tweet, a shift in the weather, or a sudden change in interest rates, you're basically seeing an organisation as an open system in action. It's a bit of a shift from the old-school way of thinking where a company was seen as a self-contained machine that just churned out products in a vacuum. Honestly, the idea that any business can survive by closing its doors and ignoring the outside world is pretty much a myth in the modern age.
Thinking about an organisation this way changes everything about how we manage people and projects. Instead of looking at a company as a rigid structure with fixed walls, imagine it more like a living organism—something like a cell or even a human body. It needs to breathe, it needs to eat, and it definitely needs to get rid of waste to stay healthy.
Breaking down the basics
At its core, the whole "open system" concept is about flow. Everything flows in, moves through a process, and flows back out. If you stop any part of that flow, the whole thing starts to stall. Scientists and theorists usually break this down into three main stages: inputs, transformations, and outputs.
Inputs are the raw materials. But we aren't just talking about wood for a furniture factory or flour for a bakery. Inputs include things like information, money, talented people, and even the general "vibe" of the market. If you're running a tech startup, your inputs are venture capital, caffeine, and the latest coding trends.
Then you have the transformation stage. This is where the magic happens—or the work, depending on how much coffee you've had. It's the internal processing where you take those inputs and turn them into something valuable. This includes your internal culture, your workflows, and how your team talks to each other.
Finally, you get the outputs. This is the obvious stuff like the product or service you're selling. But it also includes things you might not think about, like the reputation of the brand, the waste produced, or even the satisfaction levels of the employees who just finished the project.
Why boundaries are actually blurry
In an organisation as an open system, the "walls" of the company are actually quite porous. We like to think there's a clear line between "inside the office" and "the outside world," but that line is thinner than we think.
Think about social media. A single disgruntled customer can post a video that changes your internal HR policy by Tuesday. That's the outside world forcing its way in. Or think about how a change in government regulations might suddenly make your main product illegal to ship. You can't just ignore these things; they are part of your system.
The boundary is less like a brick wall and more like a screen door. You want the fresh air to come in, but you're trying to keep the bugs out. Managing an organisation effectively means knowing when to open that door wide and when to pull the curtain shut for a bit of focus.
The feedback loop is your best friend
One of the coolest parts of this theory is the idea of feedback loops. In a closed system, you just keep doing what you're doing until you run out of gas. In an open system, you're constantly checking the "temperature" of the environment to see if you need to adjust.
There's negative feedback, which sounds bad but is actually great. It's like a thermostat. If the room gets too hot, the AC kicks in to bring it back to the set temperature. In a business, negative feedback might be a dip in sales that tells you your pricing is too high. It helps you self-correct and stay on track.
Then there's positive feedback, which is more about growth and amplification. If a new marketing campaign goes viral, that positive feedback tells the system to pour more resources into that specific area. Without these loops, an organisation is basically flying blind. It's the difference between a ship with a working sonar and one that's just drifting and hoping it doesn't hit an iceberg.
Dealing with the mess of entropy
Physics has this scary concept called entropy, which basically says that everything in the universe is slowly sliding toward disorder and chaos. If you leave a garden alone, it doesn't stay a garden; it becomes a weed-filled mess.
Organisations are the same. If you don't constantly put energy, new ideas, and resources back into the system, it starts to decay. This is why "we've always done it this way" is such a dangerous phrase. It ignores the fact that the environment is changing, and if you aren't evolving to match it, you're succumbing to entropy.
By viewing an organisation as an open system, leaders realize they have to be "entropy fighters." You have to constantly pull in "negative entropy" (which is just a fancy way of saying new energy) to keep the company alive and organized. This might mean hiring fresh talent, adopting new tech, or totally pivoting the business model when the old one starts to smell a bit stale.
There isn't just one way to win
There's a great word for this: equifinality. It's a bit of a mouthful, but the concept is simple. It means you can reach the same end goal through many different paths and starting points.
In a rigid, closed system, there's usually only one "right" way to do things. But because an open system is always reacting to a changing environment, there are a million ways to succeed. Two different companies can start with the same amount of money and the same goal, but because they interact with the environment differently, they'll take completely different routes to get there.
This is actually pretty liberating. It means you don't have to copy exactly what your competitor is doing. Your "system" is unique because your people, your location, and your specific timing are unique. You can find your own way to the finish line.
What this means for the people involved
When we stop looking at people as cogs in a machine and start seeing them as vital components of an open system, the culture shifts. You realize that an employee's bad mood isn't just a "personal issue"—it's an input from the external environment (maybe they had a rough commute or personal stress) that affects the transformation process.
It also means that communication becomes the most important tool in the shed. Information is the lifeblood of an open system. If the people at the bottom of the hierarchy know something the people at the top don't, the system is broken. You need that information to flow freely so the organisation can adapt.
The big picture
At the end of the day, seeing an organisation as an open system is just a more honest way of looking at the world. We don't live in a vacuum. Our businesses are tied to the economy, the culture, the environment, and the lives of every single person who walks through the door.
It's definitely more complex than the old machine model. It's messy, it's unpredictable, and it requires constant attention. But it's also way more resilient. An organisation that knows how to listen to its environment, process feedback, and fight off entropy is an organisation that's actually built to last. It's about being flexible enough to bend so you don't break when the wind starts blowing in a new direction.
