Business & tech-leadership vocabulary¶
At a glance
Priority: P0 · Complexity: ⅗ · Est. time: 3 h · Phase: 1 · Prereqs: none (pairs with word nuance & register, collocations & precision) You're done when: you can use 40 of the 70 words below accurately in your own sentences about your work (not just recognise them), and you know the collocations and register of each.
Why it matters¶
Vocabulary range is what separates "clear" from "authoritative". A Staff engineer is expected to name things precisely: bottleneck vs constraint, mitigate vs resolve, mandate vs remit, dependency vs blocker. The words below are the working vocabulary of design reviews, exec updates, strategy documents and interviews. They are grouped by function (what you want to do with language), not alphabetically, because you retrieve words by intent ("I want to say we reduced the risk"). Learn each word with its collocations and one example sentence from your own work; recognition is not enough.
Core concepts¶
How to learn a word properly (5 layers)¶
- Meaning (in your own words, in English).
- Grammar (verb pattern, countable/uncountable, prepositions: mitigate the risk of, a mandate to).
- Collocations (what it goes with: mitigate risk, mitigate impact, not mitigate a problem as often).
- Register (formal, neutral, informal; jargon; overused buzzword).
- Own sentence about your current work; say it aloud.
Buzzword warning. Some words here (leverage, synergy, ecosystem, disrupt, paradigm) are so overused that many readers roll their eyes. Where a word carries that risk, the table says so and gives a plain alternative.
A. Assessing and analysing (understanding a situation)¶

Questions¶
L1 - Recall¶
Q1. What is the difference between imply and infer?
Answer
The speaker or writer implies (suggests without saying directly); the listener or reader infers (draws a conclusion). "Her silence implied disapproval; I inferred that she disagreed."
Q2. Distinguish responsible and accountable.
Answer
Responsible = does the work; accountable = ultimately answerable for the outcome (one person). RACI models use both; in everyday speech people blur them, but at Staff level the difference is expected.
Q3. Which verb means to reduce the severity of a risk without eliminating it: mitigate, eliminate, remediate?
Answer
Mitigate. Eliminate removes it; remediate fixes something that is already wrong (typically vulnerabilities/compliance issues).
Q4. What does \"the platform is comprised of six services\" get wrong, according to traditional usage?
Answer
Traditionally, comprise means "to contain": "The platform comprises six services" (or "is composed of / consists of"). "Comprised of" is widespread and increasingly accepted, but editors still flag it in formal writing.
L2 - Apply¶
Q5. Fill: assess / mitigate / escalate / corroborate / deprecate. (a) \"We need to ___ the impact before deciding.\" (b) \"A canary release helps ___ the risk.\" © \"The logs ___ the customer's timeline.\" (d) \"We will ___ the v1 API in June.\" (e) \"I ___ the issue to the VP.\"
Answer
(a) assess; (b) mitigate; © corroborate; (d) deprecate; (e) escalated.
Q6. Replace the buzzwords with precise language: \"We will leverage synergies across the ecosystem to drive a paradigm shift and deliver a robust, scalable solution.\"
Answer
"We will reuse the shared authentication and logging services so that each team ships features 30% faster, and we will design the platform to handle ten times today's traffic." Concrete nouns, numbers, no empty words. (Numbers are illustrative; in real writing, use your data.)
Q7. Complete with a word from the list: \"Our ___ is to reduce cloud costs by 20%, but headcount is outside our ___.\"
Answer
mandate; remit (or "scope"/"authority"). Mandate = authority to act; remit = area of responsibility.
Q8. Write one sentence for each: (a) a trade-off, (b) a blast radius, © buy-in, (d) single point of failure, all about your current system.
Answer
Model: (a) "The trade-off is between strict consistency and write latency." (b) "Per-tenant cells limit the blast radius to one customer." © "We need buy-in from the security team before we change the auth flow." (d) "The scheduler is currently a single point of failure." Check yours uses correct prepositions (trade-off between X and Y).
L3 - Judge and choose¶
Q9. Feasible, viable and practical: choose for \"A full rewrite is technically ___ but not ___ given our team size.\"
Answer
"feasible ... viable" (or "practical"). Feasible = possible to do; viable = able to succeed in the real world (economic, organisational); practical = sensible in practice. The contrast between "can be done" and "makes sense" is the point.
Q10. In a design review, is \"robust\" a useful word? What do you write instead?
Answer
It is vague unless qualified. Say robust against what: "tolerates a 30-second outage of the payment provider", "retries with exponential backoff and idempotency keys". Precise failure modes beat adjectives; use robust only after you have said what the robustness is.
Q11. \"Significant\" in a data update: when is it safe to use?
Answer
Use significant for statistical significance when you have run a test, and add the measure (p-value or confidence interval) if the audience expects it. For general size, use a quantity ("a 12% reduction") or substantial, notable. Overusing significant invites the question "statistically or practically?".
Q12. \"We need alignment\" vs \"We need consensus\" vs \"We need buy-in\": how do the three differ?
Answer
Alignment: shared understanding of direction and priorities (people may still disagree on details). Consensus: general agreement on a decision (nobody strongly objects). Buy-in: active commitment to support and carry out the decision. You can have alignment without buy-in ("we understand, but we won't staff it").
L4 - Real-world decisions¶
Q13. You are writing a one-page memo to persuade a skeptical VP of Finance to fund tooling. Choose eight words from the lists and outline how they structure the argument.
Answer
Example: state the baseline (current cost and incident hours), name the constraint (headcount), present the rationale and trade-off (cost now vs risk later), quantify the exposure (revenue at risk), show a pragmatic phased option that de-risks delivery, give a tangible metric and a contingency, and ask for a mandate with a decision date. Each word carries a slot in the argument, which is the point of learning vocabulary by function.
Q14. A new joiner overuses \"leverage\" and \"synergy\" in updates and the team mocks it. How do you coach them?
Answer
In a private 1:1, say that the ideas are good and the words are hiding them; ask for the concrete thing ("What exactly are we reusing?"). Offer three swaps (use, reuse, combined benefit) and show one rewritten sentence. Don't ridicule the vocabulary; explain that senior readers scan for specifics and treat buzzwords as a signal of vagueness.
Q15. In an interview, you want to sound precise but not pompous. How do you choose between utilise/use, facilitate/help, commence/start?
Answer
Default to the plain word; formal words signal distance, not intelligence. Choose the formal word only if it adds precision (remediate vs fix for vulnerabilities) or matches a formal document type (contract, policy). In speech, the plain word is almost always better. The test: would a respected senior colleague say it aloud in a meeting?
Real-world use cases¶
- Design review: trade-off, constraint, bottleneck, blast radius, dependency.
- Exec update: mitigate, escalate, contingency, exposure, runway.
- Strategy doc: mandate, remit, trajectory, headwinds, rationale, portfolio.
- Vendor negotiation: due diligence, provision, compliance, leverage (concrete), concession (see negotiation).
- Interview: spearheaded, orchestrated, streamlined, championed (used honestly and with numbers).
Pitfalls & anti-patterns¶
- Learning words without collocations or prepositions.
- Using a word because it sounds senior, not because it fits (utilise, leverage, holistic).
- Confusing near-synonyms (assure/ensure, imply/infer, affect/effect, comprise/compose).
- Using exponential for "fast", literally for emphasis, significant without a test.
- Learning 100 words once instead of 5 words a day with review.
- Using new words only in writing; if you never say them aloud, they will not surface in meetings.
Checklist¶
- I classified the 70 words red/yellow/green and made a plan for the reds.
- I wrote one real sentence for at least 40 words.
- I use ten of them in a real update or RFC this week.
- I can distinguish the confusable pairs in section H without notes.
- I answered all L3 questions out loud in under 3 minutes each.
