Explaining Technical Concepts

Warm-up: No jargon allowed

2 warm-up questions

• Have you ever explained something technical to a friend or family member and watched their eyes glaze over? What were you trying to explain?
• First try: I'm your grandmother. Explain to me what "the cloud" is — 30 seconds, go.

Bridging the Technical Gap One of the most valuable skills in tech is explaining complex concepts to non-technical people. Whether you're talking to clients, managers, or other departments, clear communication is essential. Strategies for clear explanation: 1. Know your audience: Adjust complexity based on their background 2. Use analogies: Compare technical concepts to everyday things 3. Avoid jargon: Replace technical terms with plain language 4. Focus on benefits: Explain what it does, not how it works 5. Check understanding: Ask if they have questions Example: Instead of: "We implemented a caching layer to reduce database queries." Say: "We added a feature that remembers frequently requested information, so the system responds faster."

Reading: Three model explanations

Read a 290-word text about Three model explanations

Three model explanations The same four moves each time: plain words, one analogy, the benefit, a check. Three different audiences, three complete performances. The outage, explained to a client "Yesterday some pages took a long time to load — I want to explain what happened. The system that stores your customer data got overwhelmed with requests. It's like one librarian trying to fetch books for two hundred people at once — nobody gets served quickly. We've added more capacity, so even on your busiest day the site will stay fast. Does that cover what you wanted to know, or shall I go into the timeline?" "The cloud", explained to a grandparent "You know how you keep photo albums on the shelf at home? The cloud is like keeping your albums in a very safe building in town instead — your photos aren't stored ON your phone, they're stored there, and your phone just looks at them. That's why if you drop your phone in the sea, the photos are all still safe. Want me to show you where yours are?" The three-month rebuild, explained to a manager "You asked why this rebuild takes three months when the feature 'already works'. Honest answer: the current code is like a kitchen where every appliance is wired through the same plug — it works, but every time we add something, we risk blowing the lot. The rebuild gives every appliance its own socket. The benefit for you: after this, new features ship in days instead of weeks, with far fewer surprises. What would you like to see first — the timeline or the risks?" Notice what's missing from all three: not one technical term. The expertise shows in the clarity, not the vocabulary.

Practice: Simplify the Jargon

Gap-fill exercise, 5 items

• Instead of saying 'API', you could say 'a way for programs to ____ to each other'.
• The cloud means storing data on the ____ instead of your computer.
• A bug is an ____ in the software that causes problems.
• To deploy means to ____ the software for users.
• A scalable system can handle ____ without slowing down.

Practice: Fix the Jargon

Error-correction exercise, 4 items

• We need to optimize the algorithm to improve UX.
• The latency is too high on this endpoint.
• We should refactor the legacy codebase.
• The backend is throwing exceptions.

Dialogue: Explain to a Non-Technical Colleague

Role-play: A marketing colleague asks you to explain a technical issue (3 lines)

• Hey, what happened to the website yesterday? Customers were complaining it was really slow. Explain the database issue in simple terms - think of an analogy like a library or filing system
• Is it fixed now? Will it happen again? Explain what was done to fix it and prevent future issues
• Should I tell customers anything specific? Give practical advice for customer communication

Discussion: Your mission: the jargon-free minute

3 discussion questions

• Mission: pick a real concept from YOUR work or studies and explain it to your tutor, who plays a smart non-technical listener. Success = under a minute, zero jargon (tutor: raise a hand at every technical term), exactly one analogy, the benefit stated, and a check question that isn't "does that make sense?".
• Second take: same concept, new audience — explain it to a 10-year-old, then to a CEO with 30 seconds between meetings. What changes, what stays?
• Replay the warm-up: explain "the cloud" to your grandmother again. Count the jargon this time — and notice which of the four moves was missing before.
