Adaptable starting points.
TESTING AN IDEA
"Here is my plan: [describe]. What assumptions does it depend on? Which is most likely wrong? What would make it fail?"
GETTING OBJECTIONS
"What are the three strongest objections to this? Argue them properly rather than listing them."
COMPARING OPTIONS
"Compare these options on [my criteria]. Table format. State trade-offs rather than declaring a winner. Details: [supply real information]."
FINDING WHAT YOU MISSED
"Here is my plan. What questions should I be asking that I have not? What is missing?"
ANALYSING FEEDBACK
"Here are customer responses: [paste]. What themes appear and how often? Quote an example of each. Include minority views, not just common ones."
A DECISION
"I am deciding between [options]. My constraints: [supply them]. What would have to be true for each to be right? What am I probably not considering?"
THE PROMPT THAT MATTERS MOST
"What would have to be true for this to be the wrong decision?"
