How to Master the Art of Explaining Technical Dependencies.

by

I want to talk about something super important for anyone who writes about technology: explaining how all the pieces fit together. You know, those invisible connections, or “technical dependencies.” It’s not just about spitting out information; it’s about making people get it, so they can make smart choices and really trust what you’re saying. This guide is all about how to take those tangled webs of connections and turn them into something clear and easy to understand.

So, Why Do Technical Dependencies Even Matter, and Why Are They So Hard to Explain?

Think of technical dependencies as the secret sauce that makes everything work – or not work! In any piece of software, any system, any process, they’re lurking in the background. They dictate what something can do, how fast it runs, if it’ll crash, and even if it’s secure. When you understand them, it’s like having X-ray vision. You can see problems coming, build things better from the start, and put your efforts where they’ll do the most good. If you ignore them? Prepare for chaos, endless delays, and constant firefighting.

Explaining them is tough because they’re:

  • Abstract: You can’t touch them like a physical object. They’re ideas, relationships.
  • Interconnected: Poke one, and ripples go everywhere.
  • Contextual: What they mean changes depending on the system and its purpose.
  • Jargon-heavy: Technical terms can feel like a brick wall.
  • Dynamic: They’re always changing as systems grow and new tech comes out.

My job, and yours, is to untangle all that mess. To make the invisible visible, and the abstract concrete.

The Secrets to Clarity: How I Structure My Explanations

Good communication doesn’t just happen. It’s a deliberate choice about how you frame things.

1. The “So What?” Principle: Why Should Anyone Care?

Before I even start explaining how something works, I always ask: “Why does this matter?” This is my “So What?” principle. If my audience doesn’t understand what happens if a dependency is there (or isn’t), they’ll just zone out. They won’t care about the nitty-gritty details.

My Strategy: The Impact Statement

I kick off an explanation of a dependency with a short, punchy sentence that answers: “Why should you care about this?”

  • Take this for example (Software Microservices):
    • Not great: “Service A depends on Service B for data processing.” (Doesn’t tell me much)
    • Much better: “Service A, which is where all our customers place orders, absolutely needs Service B to check inventory in real time. If Service B isn’t working perfectly, customers could order things we don’t have, leading to huge headaches with fulfilling orders and really unhappy customers.” (Now you see the clear impact on customer experience and our reputation.)
  • Or for hardware (Component Interoperability):
    • Bland: “The CPU relies on the RAM.”
    • Improved: “Your computer’s speed and its ability to do multiple things at once depend entirely on the CPU needing the RAM. If your RAM isn’t fast enough or big enough, your CPU will just sit there waiting for data, making all your applications feel slow and unresponsive.” (Clear impact on performance and how it feels to use the computer.)

2. The Abstraction Ladder: Start Broad, Then Go Deeper

A mistake I see a lot is people jumping straight into super-detailed technical stuff. My approach, the Abstraction Ladder, is different. I start with the big picture, easy-to-understand concept, and then, as people grasp that, I slowly add more specific details.

My Strategy: Layered Disclosure

  • First Layer (Concept): I define the dependency simply, using everyday words.
  • Middle Layer (Mechanism): Then, I explain how it works, introducing only the most necessary technical terms.
  • Bottom Layer (Implication/Example): Finally, I give specific situations, what could happen, or real-world examples.

  • Let’s try it with an API Dependency in Web Applications:

    • Top Layer: “When you use our mobile app to check your bank balance, the app actually needs to talk to the bank’s main system to get that information. It can’t just magically know it.” (The idea: the app needs outside info.)
    • Middle Layer: “This ‘talk’ happens through something called an API – an Application Programming Interface. Think of it like a standardized messenger service. Our app sends a request to the bank’s API, asking for your balance. The API then grabs that data from the bank’s database and sends it back to our app.” (How it works: API as a messenger.)
    • Bottom Layer: “So, if the bank’s API is slow, your balance might take longer to show up. If it’s completely down, you won’t be able to see your balance in the app at all, even if your internet is fine. This dependency means the app only works if that API is available.” (What happens if it goes wrong: performance, availability.)

3. The Analogy Anchoring: Explaining the Unknown with the Known

I love using analogies because they’re so powerful. They connect the unfamiliar technical stuff to things people already understand from their daily lives. They give you an instant mental picture, making abstract ideas feel real.

My Strategy: Carefully Picked Analogies

I make sure my analogies are:
* Relatable: Things everyone knows.
* Accurate (enough): Not so simple that they warp the truth, but simple enough to grasp.
* Consistent: If I use a cooking analogy, I stick with it.
* Concise: No overly complicated analogies that just add more confusion.

  • Example (Database Dependency for a Website):
    • The dependency: A website needing its database.
    • My analogy: “Imagine a website is like a giant library. The pages you see are like the books and shelves. But all the actual content – user accounts, product descriptions, blog posts – isn’t physically on those pages. It’s stored in a separate, super organized reference section: the database. So, just like a librarian needs to go to the reference section to find specific info, the website has to ‘ask’ the database for the content it shows you. If that database is like a reference section that’s locked or a total mess, the website can show you empty shelves, but not the valuable information.”
  • Example (Software Library Dependency):
    • The dependency: A new software feature needing an existing software library.
    • My analogy: “Imagine you’re building a LEGO spaceship. Instead of making every single unique part from scratch, you’d use pre-made, standard LEGO blocks like wings, cockpits, or engines. These pre-made blocks are like software libraries. Our new ‘hyperspace jump’ feature needs a really complex math calculation. Instead of writing that whole calculation ourselves, we rely on an existing ‘math library’ – a pre-built LEGO block that already knows how to do those calculations. This dependency saves us a ton of time and effort, but it also means our hyperspace jump won’t work if that math library has a bug or isn’t there.”

How I Get Super Precise with My Explanations

Beyond those frameworks, really clear language and smart structure are key.

4. The Cause-Effect Chain: Showing the Ripple Effect

Dependencies are rarely isolated. If one thing changes or breaks, it can start a whole chain reaction. I always clearly explain these cause-effect chains so my audience is prepared for potential problems and understands how everything is connected.

My Strategy: Describing the Flow Step-by-Step

I use clear linking words and phrases that show sequence, conditions, and consequences.

  • “Because X happens, then Y will happen. This, in turn, leads to Z.”
  • “If A fails, B won’t be able to… which results in C.”
  • “Depending on P means that any instability in P will directly spread to Q, impacting R.”

  • Example (Microservice Chain):

    • “Our order processing service (Service A) needs the payment gateway service (Service B). If Service B has even a brief outage, Service A won’t be able to process new payments. This dependency also affects our inventory management system (Service C) because unprocessed payments mean items aren’t truly reserved, which could lead to us accidentally overselling things and having incorrect stock numbers.” (Shows a clear chain of failure.)
  • Example (Network Interdependencies):
    • “All our company’s internal communications rely on our VPN tunnel service. This service, in turn, needs a stable internet connection from our main internet provider (ISP). If the ISP has a service interruption, the VPN tunnel will go down, making all internal communication, like email and messaging, unavailable for remote employees. This directly impacts how smoothly we can operate.” (Shows the cause-and-effect on operations.)

5. The “What If?” Scenario: Addressing Problems Before They Happen

I always try to think ahead to questions my audience might have or misunderstandings that could arise. The “What If?” scenario technique lets me address potential failure points or different situations head-on.

My Strategy: Asking Hypothetical Questions

I pose a common “what if” question and then give the direct answer.

  • “What happens if…? The direct consequence is…”
  • “If X were to fail, the impact would be…”
  • “Unlike Y, where Z is independent, here X has a hard dependency on P, meaning…”

  • Example (Cloud Service Dependency):

    • “Our entire data analytics pipeline runs on AWS Lambda functions. What happens if AWS has a regional outage? Because our system absolutely needs Lambda for its calculations, all data processing would immediately stop, leading to a significant delay in our reports. That’s why we have a backup plan that involves caching data.”
  • Example (Third-Party Library Updates):
    • “Our security scanner software uses a third-party vulnerability database. What if that third party stops updating their database? Our scanner would gradually become less effective at finding new threats, leaving us exposed over time. This dependency means we have to regularly review our vendors and consider other data sources.”

6. Visual Reinforcement: Beyond Just Words

Even though I’m mostly talking about writing here, I know how important visuals are. Even if I’m not creating diagrams, I write in a way that helps people mentally picture things, or that makes it easy for someone else to turn my words into a diagram. Good explanations often suggest or lend themselves to visuals.

My Strategy: Using Descriptive Visual Language

Even without actual images, I use words that help the reader build a picture in their mind.

  • “Imagine a direct line connecting A to B.”
  • “Visualize a hub-and-spoke model, where X is the central hub…”
  • “Picture a chain reaction where…”

  • Example (Microservice Architecture):

    • “Think of our banking system as a series of specialized departments (microservices), each critical for a banking operation. The ‘Account Balance’ department (Service A) doesn’t keep track of your transaction history itself. Instead, it relies on the ‘Transaction Ledger’ department (Service B) for that data. So, every time you ask for your account balance, Service A must check with Service B. If Service B isn’t available, Service A effectively shuts down when it comes to balance inquiries, even if other departments are working.” (This describes an invisible process using visual terms.)

The Art of Omission: What I Don’t Explain

Just as important as what I put in is what I strategically leave out. Clutter is the enemy of clarity.

7. Strategic Granularity: Knowing When to Stop

Not every technical detail is relevant for someone to understand the dependency. If I overload with specifics, people get confused and lose sight of the main point.

My Strategy: The “Need-to-Know” Filter

Before I include a detail, I ask myself: “Does my audience absolutely need this specific piece of information to grasp what this dependency is, what it means, or how to fix it?” If the answer is no, I simplify it or just leave it out.

  • Example (Database Connection Details):
    • Unnecessary Detail: “The e-commerce platform relies on a PostgreSQL 14 database, specifically connecting via JDBC drivers with a connection pool size of 20 and a maximum idle time of 5 minutes.” (Too much detail for someone who just needs to know if the website works.)
    • Appropriate Granularity: “Our e-commerce platform has a critical dependency on its underlying database to store all product information, customer data, and order history. Without a healthy connection to this database, no products would display, and no orders could be processed.” (Focuses on the what and why of the dependency, not the nitty-gritty of the connection.)
  • Example (Networking Protocol Specifics):
    • Unnecessary Detail: “The data transfer service utilizes TCP/IP for reliable packet delivery, specifically relying on SYN-ACK handshakes for connection establishment and flow control mechanisms like sliding windows for efficient throughput.” (Too deep into networking minutiae.)
    • Appropriate Granularity: “Our data transfer service depends on a stable network connection to reliably move large files between our servers and the cloud. Any significant network latency or packet loss directly impacts the speed and success rate of these transfers, potentially delaying critical data availability.” (Focuses on the impact of network health, not the specific technical details of the protocol.)

8. Jargon Management: Translate, Don’t Just Tell

Technical jargon is great for experts, but for others, it’s a closed book. My job is to translate.

My Strategy: The “Three Times Rule” and Glossary Integration

  • Translate on First Use: When I introduce a technical term, I explain it right away, the first time it appears.
  • Contextual Reinforcement: I use that plain language explanation a second time soon after to really make sure it sticks.
  • Third Time Use: After two clear explanations, I feel comfortable using the term normally, assuming people get it.
  • Optional Mini-Glossary: For documents with a lot of terms, a short glossary at the end or a linked section can be really helpful.

  • Example (Explaining “Container Orchestration”):

    • “Our application relies heavily on container orchestration, which is essentially an automated system for managing and deploying software in isolated packages called ‘containers.’ Think of it as a highly intelligent manager for hundreds or thousands of miniature virtual machines that helps our application components run efficiently, even when demand changes. Without this automated management, deploying updates or scaling our services would be a slow, manual, and error-prone process.” (The term is explained, then reinforced with an analogy and its impact.)

Making the Message Shine: Polish and Readability

Even perfect explanations can fall flat if the writing isn’t easy to read.

9. Active Voice and Direct Language: The Clearest Path

Passive voice can make things unclear about who’s doing what. Direct, active language makes dependencies much clearer and more impactful. I avoid vague words or overly academic language.

My Strategy: Focus on Subject-Verb-Object

I always identify who (or what) is doing the action, what the action is, and who (or what) is receiving that action.

  • Passive/Indirect: “Data is retrieved by the system from the external API.”
  • Active/Direct: “The system retrieves data from the external API.” (Clearer about who does what.)

  • Passive/Indirect: “Problems will be experienced by users if the authentication service is down.”

  • Active/Direct: “If the authentication service is down, users will experience problems logging in.” (More immediate and impactful.)

10. Iterative Review and Feedback: The Final Test

You’re just too close to your own writing to see its flaws. Fresh eyes are priceless.

My Strategy: The “Non-Technical Friend” Test

I always have someone who isn’t a tech expert read my explanation. I ask them:

  • “What’s the main point about this dependency?” (Checks if they grasped the core idea.)
  • “What happens if this dependency breaks?” (Tests if they understood the impact.)
  • “Is anything confusing or unclear?” (Helps me find jargon or awkward phrasing.)
  • “Would you feel confident explaining this to someone else now?” (This really tells me if they truly understood it.)

I listen very carefully to their feedback. If they struggle, I know I need to refine my explanation even more.

Final Thoughts: The Power of Understood Dependencies

Mastering how to explain technical dependencies isn’t just a writing trick; it’s absolutely essential. It empowers everyone involved, speeds up projects, reduces risks, and builds a culture where everyone makes informed decisions. By using the “So What?” principle, climbing the abstraction ladder, employing powerful analogies, and using direct, precise language, I can transform the intimidating complexity of technical connections into clear, actionable stories. The ability to articulate these invisible threads is what makes technical communication truly impactful. Ultimately, this mastery leads to successful projects, happy users, and teams that work with clarity and purpose.
