Task Decomposition Strategies
Audience: professionals who use Claude at work, no coding or API knowledge needed. Anything marked verified was checked against Anthropic's documentation or help center on 2026-10-16. Design guidance is widely taught practice, not a documented rule.
Why decompose (design guidance)
One huge request ("analyse our market, write the strategy, build the deck") produces shallow results and hides where mistakes came from. Smaller steps are easier to check and correct.
How to split
| Big task | Steps |
|---|---|
| Write a report from raw notes | 1. Extract key points. 2. Group into themes. 3. Draft an outline. 4. Draft each section. 5. Review against the brief |
| Analyse customer feedback | 1. Clean and label comments. 2. Count themes. 3. Pick top issues with example quotes. 4. Recommend actions |
| Prepare for a meeting | 1. Summarise background. 2. List decisions needed. 3. Draft questions. 4. Create a one-page brief |
Rules of thumb:
- One clear output per step, which becomes the input to the next.
- Check each step before continuing; fix early errors, not at the end.
- Keep a running summary of decisions so you can paste it forward.
- Order matters: understand before you decide, decide before you draft.
- Ask Claude to propose the plan first: "Before you start, list the steps you would take and any questions you have."
Asking Claude to review its own draft (verified pattern)
A common sequence is draft, then review against criteria, then refine, each as a separate message. This lets you inspect each stage. (For high-stakes work, have a person review, not only Claude.)
When not to split
A short, well-defined task (rewrite this paragraph, translate this email) does not need steps.
Exam traps
- One mega-prompt for a multi-part job.
- Skipping the check between steps.
- Losing decisions between chats; carry forward a summary.
- Splitting a simple task into needless steps.
