Why This ChatGPT Prompt for “Write a Case Study” Works Better
When you type “Write a case study about [client/project] results” into ChatGPT, it lacks structure — ChatGPT has to guess what format you want, how detailed to go, and what to prioritize. The optimized version removes that guesswork.
It uses Markdown headers to organize the task, adds bounded constraints (specific numbers, word counts, formats), and places the most critical instructions at the end — where ChatGPT pays the most attention.
