The Ultimate Guide to System Design/Architecture

How Should You Start?

The most important thing is to start with a Large Overview. Draw out a simple first sketch of your business. What are the main parts? How do they connect? Once you’ve got the big picture, you can “fly down” and look at the smaller details. Some areas, like marketing or product development, can often be improved just by seeing how they fit into the overall system.


What Kind of Diagrams Should You Create?

Here are your useful types of diagrams explained simply:

  • UML Diagrams: These help you understand how things work together. Imagine you’re planning a group project; UML diagrams show who does what and how everything fits.

  • ER Diagrams: Think of these as maps of relationships—like how customers connect to products or orders.

  • Flowcharts: Step-by-step guides. Perfect for showing a process, like how your product gets from an idea to a finished item.

  • Network Diagrams: Imagine drawing your Wi-Fi setup—routers, devices, connections. Network diagrams do this for businesses.

  • Architecture Diagrams: These give you a bird’s-eye view of your whole system. They show how everything comes together, like a map of a city.

  • Process Flow Diagrams: These are like blueprints for specific tasks, showing each step in a process clearly and simply.


When Should You Design Your System?

The answer is simple: all the time. Your system should grow and evolve with your business. Think of it like keeping a journal for your company—always up to date, always useful.


What You Need to Learn

We all know that to reach a goal, you need a plan and clear steps to follow. But here’s the thing: You don’t need expensive software or a huge team of experts to get started. You just need to start designing.

Yes, it’s not fun at first, and there’s a little learning curve. Let’s be honest: creating things is more exciting than organizing them. But that’s the line between success and failure. The businesses that succeed are the ones that take time to organize their systems.


Systematron's Tip

Take just a little time out of your day to sketch out what you’re doing. It doesn’t have to be perfect—it just needs to give you a clear overview of your system. Having this bird’s-eye view will make it so much easier to grow, fix problems, and make the right decisions.

Remember, a business that isn’t visualized is a business waiting to fail. Take the time to plan it, step by step, and watch your business thrive.


Dive Deeper into each Diagram:


1. UML Diagrams

UML diagram

Function:UML diagrams are used to show how systems or processes interact. They’re perfect for planning workflows, designing software systems, or organizing team roles.

How to Build in Systematron:

  1. Open Systematron and create a new diagram.

  2. Select a UML Template from the template library or start with a blank canvas.

  3. Drag Shapes: Use rectangles for objects, diamonds for decisions, and arrows to show relationships.

    • Example: A class diagram shows different objects (like "Customer" or "Product") and their attributes.

  4. Connect Elements: Drag lines to connect the shapes, representing interactions or relationships.

  5. Label Clearly: Click on shapes and lines to add descriptive labels (e.g., “places order,” “has attributes”).

  6. Save or Export: Save the diagram for collaboration or reference.


2. ER Diagrams (Entity-Relationship Diagrams)


ER Diagram

Function: ER diagrams map relationships between data entities. Ideal for designing databases or understanding how data flows within your business.

How to Build in Systematron:

  1. Start with a Blank Diagram: Click “New Diagram” and select the ER diagram template.

  2. Add Entities: Drag rectangles to represent entities like "Customer," "Order," or "Product."

  3. Define Relationships: Drag diamonds (relationship symbols) and connect them to the entities.

  4. Add Attributes: Use ellipses (ovals) to add details about the entities (e.g., “Name,” “Price”).

  5. Review Connections: Ensure every entity is linked logically with lines to show relationships.

  6. Adjust Layout: Use Systematron’s “Auto Layout” feature to clean up the diagram.


3. Flowcharts

Flowchart Business System

Function:Flowcharts show the sequence of tasks in a process. They’re great for mapping workflows, customer journeys, or decision-making steps.

How to Build in Systematron:

  1. Select a Flowchart Template or start from scratch.

  2. Drag Symbols: Use rectangles for tasks, diamonds for decisions, and arrows for flow.

    • Example: Start with “Receive Order,” then link to “Process Payment.”

  3. Connect Steps: Drag lines between symbols to show the order of tasks.

  4. Add Text: Click on shapes to label each step clearly.

  5. Style It: Use Systematron’s color and alignment tools to make it easier to read.


4. Network Diagrams

Network Diagram

Function:Network diagrams show how systems, tools, or teams connect. Useful for IT infrastructure planning or mapping team communications.

How to Build in Systematron:

  1. Start with the Network Template or create a blank canvas.

  2. Add Nodes: Drag icons to represent servers, devices, or tools (e.g., “Router” or “Marketing Tool”).

  3. Connect Nodes: Use lines to show how systems are linked.

  4. Label Connections: Add notes to lines, like “Wi-Fi” or “Database Access.”

  5. Group Items: Use the grouping feature to cluster similar components, such as all devices in one department.


5. Architecture Diagrams

Architecture Diagram

Function:Architecture diagrams provide a high-level view of your system or business structure. Great for seeing how tools, departments, or workflows interact.

How to Build in Systematron:

  1. Choose the Architecture Template or start blank.

  2. Add Components: Drag and drop shapes to represent departments, tools, or workflows.

  3. Show Interactions: Draw lines or arrows to illustrate dependencies or communication flows.

  4. Categorize: Use color-coding or labels to organize components by type (e.g., marketing, operations, IT).

  5. Review and Refine: Use Systematron’s alignment tools to keep the diagram clean and professional.


6. Process Flow Diagrams

Process Flow Diagram Customer Journey

Function:Process flow diagrams map the steps in a specific process, like product development or customer onboarding.

How to Build in Systematron:

  1. Open the Process Template: This gives you a starting layout for workflows.

  2. Add Steps: Drag rectangles to represent each step in the process (e.g., “Design,” “Test,” “Launch”).

  3. Connect Steps: Use arrows to show the sequence and direction of flow.

  4. Include Inputs/Outputs: Use smaller shapes to show materials or results at each step.

  5. Finalize: Add labels to clarify each step and review the flow for completeness.


Key Tips for Systematron:

  • Save Frequently: Use Systematron’s cloud-saving feature to avoid losing your work.

  • Collaborate: Share your diagrams directly with your team for feedback or updates.

  • Revisit Often: Your system should evolve with your business, so update diagrams as needed.
