The prompt

Prompt · 5 blanksBlanks in capitals
Write a portfolio case study about a project I worked on, to show employers hiring for TARGET ROLE what I did and how I think.

Use this:
- The project and its context: PROJECT SUMMARY
- My role, and what I did myself versus with the team: MY ROLE AND CONTRIBUTION
- Steps, key decisions and trade-offs I made: PROCESS AND DECISIONS
- Results, with numbers where I have them: OUTCOME AND EVIDENCE

Write it in first person, 500-700 words:
1. A title and a one-sentence summary a recruiter can take in within five seconds.
2. The problem: who it affected and why it mattered (2-3 sentences).
3. My role: title, team size, timeline and what I owned.
4. Process: three or four steps, each with one decision I made and why.
5. Outcome: results and evidence, then one thing I'd do differently next time.
6. Two or three suggested visuals (sketches, before and after, charts) and what each should show.

Rules:
- Never invent results, numbers or quotes. Where a metric is missing, write "add metric" in capitals so I can fill it in.
- Use "I" for my own work and "we" for team work; don't claim credit for what others did.
- Leave out client names and confidential figures unless I've said they're public.
