Have you ever built a magnificent castle with LEGO blocks? 😊 Just as numerous individual blocks fit together in their places to become a single, amazing castle, the world around us is also made up of countless ‘systems.’ We use the word ‘system’ so often in our daily lives and at work. But if someone suddenly asks, “What exactly is that?” it can feel a bit tricky to explain. I’ve been there too. Today, let’s take some time to turn that ambiguity into refreshing clarity!
A System: More Than Just a Sum of Its Parts? 🤔
The first thing to remember is that a system is different from a mere ‘collection’ of various elements. A pile of stones scattered on the roadside is just a ‘collection,’ not a system. Why? Because there’s no interaction or common goal among the stones.
The core of a system is that it’s an ‘organic assembly of interacting components designed to accomplish a common purpose.’ The key words here are ‘purpose,’ ‘interaction,’ and ‘organic.’ This means the parts of a system don’t operate separately; they work together like gears turning towards a single goal. In this process, a synergy effect occurs where ‘1+1=3’ instead of ‘1+1=2,’ and this is the true power of a system.
In Systems Engineering, understanding this ‘system’ is the starting point for everything. To solve complex, intertwined problems and create efficient outcomes, one must approach it from the perspective of the entire ‘system,’ not just individual parts.
The 5 Essential Conditions for a Perfect System 🧩
For anything to be called a ‘system,’ it must have several essential components. Just like a delicious bibimbap can’t be complete without fresh vegetables and savory sesame oil. Let’s look at the five key elements that make up a system, shall we?
- Objective: Every system has a clear purpose, an answer to ‘why it exists.’ A car’s objective is to ‘transport people or goods safely and quickly.’
- Components: These are the parts needed to achieve the objective, such as hardware, software, people, and rules. For a car, this would be the engine, wheels, steering wheel, etc.
- Interaction: Components don’t move independently; they are closely connected, exchanging information and influencing each other. Just like when a driver turns the steering wheel, the direction of the wheels changes.
- Boundary: This is an invisible line that separates the system’s interior from its exterior. It defines what is included in the system and what is not.
- Environment: These are external factors that exist outside the system’s boundary and affect the system, but which the system cannot directly control. Road conditions or weather affect a car’s operation, but the driver can’t control them.
Finding Examples of Systems Around Us 🚗💻
“Hmm, still a bit abstract?” You might be thinking that. So, I’ve compiled a table of system examples that are easy to find around us. It will be much easier to understand this way!
| System Example | Key Components | Objective |
|---|---|---|
| Car | Engine, transmission, wheels, control unit, driver | Safe and efficient transportation |
| Computer | CPU, memory, storage, operating system (OS), user | Data processing and information delivery |
| Human Body | Heart, brain, lungs, blood vessels, nervous system | Maintaining life functions |
| Company | Employees, departments, business processes, regulations | Profit generation and sustainable growth |
If even one component of a system fails, it can affect the performance of the entire system. For example, a single loose screw in a car can lead to a major accident. That’s why it’s crucial to consider the role and interaction of every component.
