Prompt Engineering for PMs

In short

"Write a PRD" gets you generic mush. A clear brief with context, format and limits gets you a first draft you can actually use.

Writing clear, structured prompts to get reliable output from an AI tool — useful both for building AI features and for using AI as a personal productivity tool.

The purple blob writes a careful shopping list next to a cloth bag and vegetables.

Think of it like this

The kirana list for your little brother

Send your brother with "get stuff for dinner" and he returns with chips. Write "1 kg onions, 500 g paneer, one small packet of tea, under 300 rupees, call if paneer is out" and dinner happens. Same brother. Better instructions.

Summarise this feedback

1/5A one-line prompt with 200 survey answers pasted below. No goal, no format.

The big ideas

What you need to know

Give a role and context

Say who the AI should act as and what situation it's in. Context shapes every word.

State the goal

Explain what you'll do with the output. "For a VP update" changes tone and length.

Ask for a format

Bullets, a table, under 150 words. Clear formats make output easy to check and reuse.

Show an example

One sample of what good looks like often works better than a paragraph of instructions.
