Why this matters now

Generative AI is embedded across knowledge work. The difference between ad‑hoc prompts and designed prompts is the difference between novelty and repeatable ROI. This guide gives business teams a practical system to brief AI reliably, measure quality, and scale safe usage—complete with copy‑paste templates and evaluation criteria.

Outcomes

By the end, your teams will be able to:

  • Write clear, constrained prompts that reflect business context and compliance.

  • Select the right prompt pattern for the task (summarise, generate, transform, plan, decide).

  • Measure output quality with a shared rubric.

  • Operationalise prompts: versioning, testing, approvals, and analytics.

The Anatomy of a Business‑Grade Prompt (R-TCC-COE)

Use this structure for 90% of work tasks.

  1. Role – Who the model is simulating.

  2. Task – What to do, in one sentence.

  3. Context – Audience, brand, channel, constraints.

  4. Content – The source data to use (paste, attach, or reference).

  5. Constraints – Rules: tone, length, style, compliance.

  6. Output – Exact format required (JSON schema, table, bullets).

  7. Evaluation – How success is judged (criteria, tests, or checklists).

Template
Role: [discipline + seniority].
Task: [action verb + outcome].
Context: [audience, channel, brand rules, locale].
Content: [paste data or point to files].
Constraints: [Do/Don’t, sources only, citations, word limits].
Output: [format + fields].
Evaluation: [acceptance criteria or scoring rubric].

Prompt Patterns & Examples

Below are reusable patterns with examples and acceptance criteria. Copy, adapt, and save to your workspace projects.

1) Summarise→Decide (executive brief)

Use when: Turning long docs into board‑ready decisions.

Prompt

  • Role: You are a strategy analyst for a UK SaaS firm.

  • Task: Produce an executive brief and a go/no‑go recommendation.

  • Context: Audience is the COO; British English; risk‑aware.

  • Content: <>

  • Constraints: 250–300 words; include 3 quantified risks; cite document page refs.

  • Output: Markdown with sections: Summary, Options, Risks, Recommendation.

  • Evaluation: Meets length; includes 3 risks with impact/likelihood; cites page refs.

Acceptance criteria (scored 0–2 each; target ≥8/10)

  1. Accuracy of facts

  2. Relevance to COO priorities

  3. Clarity & brevity

  4. Risk specificity with numbers

  5. Actionable recommendation

2) Transform→Standardise (policy clean‑up)

Use when: Converting messy text into approved templates.

Prompt

  • Role: Compliance editor.

  • Task: Rewrite into the company’s policy template.

  • Context: UK employment law; inclusive language.

  • Content: <>

  • Constraints: Preserve legal meaning; remove US‑only references; flag gaps.

  • Output: 1) Clean policy; 2) Change log table; 3) Gap list.

  • Evaluation: Legal meaning preserved; gaps flagged with rationale.

Acceptance test

  • If a clause is ambiguous, the model must add a “REVIEW” tag rather than resolving it.

3) Generate→Persuade (sales email sequence)

Use when: Outbound copy that matches brand voice.

Prompt

  • Role: Senior B2B copywriter in cybersecurity.

  • Task: Draft a 3‑email sequence to CFOs in FTSE 250.

  • Context: Brand voice = “Warm Intelligence”; avoid hype.

  • Content: ICP notes + 3 case studies (paste bullets).

  • Constraints: Plain language, no jargon; subject lines ≤7 words; UK spelling.

  • Output: 3 emails with subject, 120–150 words each; CTA variations.

  • Evaluation: Voice match; value prop accuracy; no spammy claims; readability (FK grade ≤8).

Quality checks

  • Run a readability pass and a hallucination check against the pasted case studies.

4) Analyse→Explain (data analysis with files)

Use when: Asking the model to analyse spreadsheets or CSVs.

Prompt

  • Role: Finance analyst.

  • Task: Analyse month‑end variances and explain drivers.

  • Context: Audience = Finance Director; highlight risks/opportunities.

  • Content: Attach: P&L_Jan–Dec_2025.csv and Budget_2025.csv.

  • Constraints: Use only attached files; show formulas; no external assumptions.

  • Output: Table: Line Item | Budget | Actual | Variance | Driver (1 sentence);
    then a 150‑word narrative.

  • Evaluation: Variances match files; explanations reference file rows.

Acceptance test

  • Spot‑check 3 rows for arithmetic correctness before sign‑off.

5) Plan→Breakdown (project planning)

Use when: Converting goals to a delivery plan.

Prompt

  • Role: Programme manager (PRINCE2/Agile).

  • Task: Build a 90‑day plan for an AI rollout.

  • Context: 50‑person UK retailer; SSO and data governance required.

  • Content: 5 high‑level goals (paste).

  • Constraints: Week‑by‑week; include owners, risks, and success metrics.

  • Output: Markdown table + RAID log + weekly status template.

  • Evaluation: Dependencies explicit; measurable milestones; risks mitigated.

The Business Prompt Quality Rubric (BPQR)

Score each criterion 0–2 (Poor / Adequate / Strong). Target ≥8/10; Mandatory criteria marked .

  1. Factual Accuracy – Matches provided sources; no invented data.

  2. Relevance – Directly serves the stated audience and goal.

  3. Clarity – Short sentences; plain English; unambiguous instructions.

  4. Structure & Format – Output exactly as specified (JSON/table/sections).

  5. Constraints Compliance – Tone, length, style guides and legal caveats followed.

  6. Verifiability – Citations, page refs, or file row refs included where asked.

  7. Safety & Privacy – No PII leakage; no policy‑violating content.

Tip: Bake this rubric into your prompts as the Evaluation step. Ask the model to self‑score, then improve until ≥8/10.

Anti‑Patterns to Avoid

  • Vague roles: “Act as an expert” without domain, seniority, and audience.

  • Missing context: No brand voice, region, or compliance notes.

  • Open‑ended tasks: “Write something great about X.” Be specific.

  • No source data: Asking for analysis without attaching files or quoting text.

  • Unbounded outputs: No format, length, or evaluation criteria.

  • Hidden requirements: Expectations not stated in the prompt inevitably fail QA.

Advanced Techniques

A) Chain‑of‑Thought Guardrails (business‑safe)

Ask for structured reasoning summaries without revealing sensitive internals:

“Provide a numbered reasoning summary (max 5 bullets) focused on the facts from the attached files; do not disclose internal model chain‑of‑thought.”

B) Few‑Shot Examples

Give 1–3 concise, high‑quality examples that mirror your desired output. Keep examples short; highlight boundaries (good/bad examples) to reduce drift.

C) Tooling & Data Controls

When using file uploads, projects, web search, or apps, explicitly constrain the data:

“Use only the attached files and the approved knowledge base. Do not browse the public web.”

D) Output Contracts (JSON)

For integrations, specify a JSON schema right in the prompt:

{
  "title": "SalesEmail",
  "type": "object",
  "properties": {
    "subject": {"type": "string"},
    "body": {"type": "string"},
    "cta": {"type": "string"}
  },
  "required": ["subject", "body", "cta"]
}

Add: “Validate JSON before responding; do not include markdown fences.”

E) Self‑Critique → Improve Loop

End prompts with: “Self‑evaluate using BPQR; list 3 improvements; apply them and present only the improved version.”

Role‑Based Prompt Packs

  • “If content could breach policy or law, halt and explain the risk.”

Red‑flag checks (ask the model to run):

  • Does the output contain PII or confidential data?

  • Are any claims unverifiable from the provided sources?

  • Is there ambiguous or discriminatory language?

Measuring ROI from Prompting

Track before/after on:

  • Time saved per task (minutes).

  • Quality score via BPQR.

  • Error rate (rework/defects).

  • Adoption (active users, prompts reused).

Simple pilot target: 3 use‑cases × 10 users × 4 weeks → publish a one‑page impact report.

  • Map 3–5 high‑impact use‑cases per function

  • Turn them into reviewed, versioned prompts with BPQR

  • Leave with a rollout checklist, templates, and success metrics

FAQ

1) What’s the minimum structure every prompt should have?
Role, Task, Context, Content, Constraints, Output, Evaluation (R‑TCC‑COE). Use the universal template in the appendix.

2) How do we reduce hallucinations?
Attach source data, forbid external browsing when not needed, demand citations/page or row refs, and require a self‑critique step before final output.

3) How do we measure quality consistently?
Use the BPQR rubric (0–2 each for Accuracy, Relevance, Clarity, Structure, Constraints, Verifiability, Safety). Target ≥8/10 and promote only “gold” prompts.

4) When should we fine‑tune vs improve prompts?
Fine‑tune when you have consistent, high‑quality examples and the same task repeats at scale. Otherwise, prefer prompt and workflow improvements plus few‑shot examples.

5) Is this safe with ChatGPT for Business?
Yes—pair prompts with appropriate data controls, avoid PII unless necessary, and use workspace policies; Business excludes training on your data by default.
