Summaries that keep the signal
Why it matters: Good summaries preserve what matters and are easy to act on.
Goals
- Summarize by purpose (not by length).
- Preserve key constraints, decisions, and risks.
- Produce an action list.
Key definitions
- Signal: The core meaning: decisions, constraints, reasons, and actions.
- Noise: Details that do not change decisions or actions.
- Compression: Reducing length while preserving signal.
Workflow (step-by-step)
- Choose a summary purpose: brief, decision memo, action plan, update.
- Extract: decisions, constraints, numbers, risks, and open questions.
- Write a 5–10 bullet “signal” summary.
- Add a “what’s missing” section (unknowns).
- Add actions with owners and dates (when applicable).
Example (good vs bad)
✅ Good: A summary that includes decisions + risks + next actions.
❌ Bad: A summary that rewrites the text with fewer words but no structure or actions.
Checklist
- Purpose stated.
- Decisions/constraints preserved.
- Actions included.
- Unknowns flagged.
Metrics / criteria
- Read time < 2 minutes; action list usable.
- Measurable: You can say whether the output is correct/complete (pass/fail or a score).
- Effort: You can produce the result in 15–30 minutes using the workflow.
- Clarity: Another person can run your prompt and get a similar outcome.
Common mistakes + fixes
- Pitfall: Summarizing without purpose. Fix: Define audience + decision context first.
- Pitfall: Vague instructions. Fix: Add constraints, examples, and a success checklist.
- Pitfall: One-shot prompting. Fix: Iterate: draft → critique → revise → verify.
- Pitfall: No validation. Fix: Add QA steps, tests, and explicit “what counts as done”.
Student tasks
- Apply the workflow to one real work task related to summaries that keep the signal.
- Create a small artifact: prompt, checklist, rubric, table, draft, or decision note.
- Run one quality check and record what changed after the check.
- Write a 3-sentence reflection: what worked, what failed, and what you will reuse.
