Every engineer hits the moment: something is broken, people are waiting, and you need to explain it clearly and quickly in English. Whether it’s a production incident, a bug report, or a technical blocker — the way you frame the problem determines how fast your team can solve it.
This lesson teaches you the exact language pattern that experienced engineers use to explain technical problems.
🗣️ Key Phrases to Say Out Loud
| Phrase | IPA | When to Use |
|---|---|---|
| ”Here’s what’s happening.” | /hɪrz wɒts ˈhæpənɪŋ/ | Opening a problem explanation |
| ”The root cause is…” | /ðə ruːt kɔːz ɪz/ | Explaining underlying issue |
| ”The impact is…” | /ðə ˈɪmpækt ɪz/ | Describing consequences |
| ”As a workaround, we can…” | /æz ə ˈwɜːkaraʊnd wiː kæn/ | Offering a temporary fix |
| ”We’re investigating.” | /wɪər ɪnˈvestɪɡeɪtɪŋ/ | Buying time while diagnosing |
| ”I need 30 minutes to confirm.” | /aɪ niːd θɜːti ˈmɪnɪts tə kənˈfɜːm/ | Setting honest expectations |
| ”Here’s my hypothesis.” | /hɪrz maɪ haɪˈpɒθɪsɪs/ | Sharing a theory before confirmation |
Pronunciation focus: hypothesis — 4 syllables, stress on 2nd: hy-POTH-e-sis (/haɪˈpɒθɪsɪs/). Most learners stress the first syllable — don’t.
📚 Vocabulary
1. root cause /ruːt kɔːz/
Nghĩa: nguyên nhân gốc rễ — the underlying reason a problem occurred Example: “The root cause was a missing index on the users table — the query was scanning the full table on every request.”
2. workaround /ˈwɜːkaraʊnd/
Nghĩa: cách xử lý tạm thời — a temporary fix that avoids the root problem Example: “As a workaround, we disabled the feature for users with large datasets until the fix is deployed.”
3. reproduce /ˌriːprəˈdjuːs/
Nghĩa: tái tạo lỗi — to make a bug happen again reliably Example: “I can reproduce the issue consistently — it happens every time the user has more than 1,000 items in their cart.”
4. scope /skəʊp/
Nghĩa: phạm vi ảnh hưởng — how wide the problem reaches Example: “The scope of the issue is limited to users in the EU region — it’s not affecting global traffic.”
5. regression /rɪˈɡreʃn/
Nghĩa: lỗi regression — a bug introduced by a recent change that broke something previously working Example: “This looks like a regression from last Tuesday’s deploy — the checkout flow worked fine before that.”
6. mitigate /ˈmɪtɪɡeɪt/
Nghĩa: giảm thiểu tác động — to reduce the severity of a problem (not necessarily fix it) Example: “We mitigated the impact by rolling back the API endpoint while we investigate the root cause.”

The Problem Explanation Framework
Use this structure every time you need to explain a technical issue:
1. WHAT — what is broken / what users see 2. SCOPE — who and how many are affected 3. ROOT CAUSE — why it’s happening (or hypothesis) 4. IMPACT — business / user consequences 5. CURRENT STATUS — what you’re doing right now 6. WORKAROUND — how users can avoid it for now 7. ETA — when a fix is expected
Practice Dialogue: Incident Update
Read this aloud as if you’re on a conference call with your manager and team:
Manager: “What’s going on with the payment service? We’re getting reports from users.”
You: “Here’s what’s happening. Users are hitting a 500 error when checking out with a saved card. The scope is limited to users who saved their card before June 15th — new cards work fine.
Our hypothesis for the root cause is a schema mismatch after last week’s migration — the old card token format is no longer being handled correctly.
The impact is roughly 12% of checkout attempts are failing. Revenue is affected.
We’re investigating right now — I need about 30 minutes to confirm the root cause before we decide whether to roll back or patch forward.
As a workaround, affected users can delete and re-add their card — that generates a new token in the correct format.
I’ll update you in 30 minutes with a fix timeline.”
Practice tips:
- Start with “Here’s what’s happening” — it signals you’re organized
- Always state the scope early — managers want to know how bad it is
- Say “our hypothesis” instead of “I think” — it sounds more professional
- “I need X minutes to confirm” is far better than “I don’t know yet”
⏱️ 5-Minute Drill
Read this incident update script aloud 3 times, getting faster and more confident each time:
“I want to give a quick update on the issue we’re investigating.
What we know: the API is returning 503 errors on the /checkout endpoint intermittently — about 8% of requests are failing.
Root cause hypothesis: we believe it’s related to connection pool exhaustion under high load. The connection limit wasn’t updated when we scaled up traffic last week.
Current status: we’ve already increased the connection pool size as a workaround and errors have dropped to under 1%. We’re still investigating whether there’s a deeper issue.
Impact: the window of high errors was about 22 minutes. Approximately 340 users were affected.
Next step: full post-mortem tomorrow. I’ll share a write-up by end of day.
Any questions before I go back to monitoring?”
🌟 Today’s Challenge
Next time you report a bug or blocker — even in a Slack message — use the framework:
- What is broken
- Who is affected (scope)
- Your hypothesis for the root cause
- What you’re doing right now
Four sentences. It’s faster to read than “the thing is broken and I’m looking at it.”
