Documenting architecture for non-engineers requires clear communication, simplification, and a focus on the key elements that will resonate with people who may not have technical expertise. The goal is to break down complex architectural concepts into digestible formats without losing the core meaning. Below is a structured approach to effectively document architecture for a non-engineering audience.
1. Understand Your Audience
Before creating any documentation, it’s crucial to know who your non-engineering audience is. Are they business stakeholders, project managers, or perhaps even customers? The level of detail and type of explanation will vary depending on whether the reader is a decision-maker or someone looking for general understanding. Tailoring your language and depth accordingly is essential.
2. Use Simple, Non-Technical Language
The most important thing when documenting architecture for non-engineers is to avoid technical jargon and complex terminology. This includes avoiding terms like “microservices,” “containers,” or “APIs,” unless you define them first.
Example of simplified language:
-
Instead of saying “The system leverages a microservices architecture,” you could say, “The system is made up of separate, smaller services that each perform a specific task and work together.”
3. Visual Representation
Architecture is inherently visual, and most people, engineers or non-engineers, find diagrams much easier to understand than written descriptions. Diagrams can represent structures, flows, and relationships in a way that text cannot. For non-technical stakeholders, visual aids like flowcharts, system diagrams, or even simple wireframes can be immensely helpful.
-
System Diagrams: High-level system diagrams that show how different components of the architecture interact can be crucial.
-
Flow Diagrams: These can show the step-by-step process of how data or users interact with the system.
-
User Interfaces (UI) Wireframes: If relevant, wireframes or mockups of user interfaces can help non-engineers understand how end-users will interact with the system.
4. Focus on the Big Picture
For non-engineers, it’s often more useful to focus on how the architecture solves problems, rather than the technical details of how the system works. Address the why and what rather than the how. The key elements to emphasize include:
-
Purpose: What problem does the architecture solve?
-
Key Components: What are the major parts of the system, and what do they do?
-
Workflow: How does information move through the system?
-
Benefits: How does the architecture improve performance, reduce costs, or benefit end-users?
5. Use Analogies
Analogies are an effective way to explain complex systems in simpler terms. Relating architecture to something non-technical—like an office building or a highway system—can make abstract concepts more concrete. For instance, you could compare a system’s server infrastructure to a building’s foundation and the services running on it to rooms or departments.
Example analogy:
-
“Think of the database as a library where information is stored. The server is like the librarian who organizes and retrieves the information when requested. The users are the people visiting the library, searching for books.”
6. Create a Glossary or Key Definitions
Even when simplifying language, certain terms will inevitably arise that may be unfamiliar to a non-engineer. A glossary or a section with simple definitions of key terms can be extremely helpful. This allows you to introduce necessary technical terms without overwhelming your reader with information upfront.
Example entries:
-
Database: A collection of information organized in a way that allows easy access and management.
-
Cloud: A way to store and access data over the internet, rather than using physical storage.
7. Provide Use Cases or Scenarios
Another effective method for explaining architecture to non-engineers is through use cases or scenarios. Describing how the architecture would be used in real-world situations can make the benefits and workings of the system clearer.
Example Use Case:
-
“Imagine a customer browsing an e-commerce website. The front-end service of the architecture allows them to search for products, while the back-end handles their payment and shipment details. The architecture ensures the customer gets their product quickly and securely.”
8. Avoid Over-Detailing
While it’s tempting to explain every component of the architecture, you don’t want to overwhelm your audience. Stick to the most important elements that directly affect the business or user experience. Details such as specific programming languages or technical configurations are often unnecessary and confusing for non-engineers.
9. Include Metrics and Success Indicators
For non-technical stakeholders, understanding the success of an architecture can often be more important than understanding the technical details. If applicable, include metrics or KPIs that show how the architecture improves performance or delivers value.
Example Metrics:
-
Speed of the website (e.g., page load times).
-
Cost savings due to efficiency improvements.
-
Increased user engagement or satisfaction.
10. Organize the Documentation Logically
The structure of the document itself plays a big role in clarity. A well-organized document with clear headings and sections will help non-engineers follow along without feeling lost. A typical structure might include:
-
Introduction: A simple overview of the architecture and its purpose.
-
Key Components: A description of the major elements in the system.
-
How It Works: An explanation of how the components interact, with visuals where appropriate.
-
Benefits: A breakdown of how the architecture benefits users and the business.
-
Use Cases: Scenarios that demonstrate how the system functions in real-world situations.
-
Glossary: Definitions of key terms used in the document.
11. Review and Get Feedback
Once the documentation is written, it’s essential to have it reviewed by someone who is representative of the target audience—someone who doesn’t have a technical background. This review process helps ensure the document is accessible and that key concepts are communicated clearly.
Conclusion
Documenting architecture for non-engineers is all about clarity, simplicity, and relatability. By focusing on high-level concepts, using analogies, visual aids, and organized content, you can bridge the gap between complex technical systems and those who may not have an engineering background. The goal is to make the architecture understandable and demonstrate how it adds value to the business, customers, or users—without drowning the audience in technical details.
