TL;DR: A concise “Pre-Mortem” technique that forces AI to identify fatal flaws in your plans before you execute them.
The Blind Spot in Planning
We are all naturally optimistic when we map out a new project. We see the goal line, but we rarely look closely enough at the potholes along the way. This Reddit user, u/Glass-War-2768, shared a brilliant, concise prompt that flips the script on standard planning by using a technique called “Anticipatory Reasoning.”
Instead of asking the AI to validate a plan, the author asks it to assume the plan has already crashed and burned. This psychological trick forces the model to switch from being a supportive assistant to a critical analyst.
The Prompt
Here is the exact prompt provided by the author:
“Here is my project plan. Imagine it is 6 months from now and the project has failed. List the 3 most likely reasons why it failed and how to prevent them today.”
Why It Works
This prompt leverages a cognitive strategy known as a “Pre-Mortem.” By shifting the temporal perspective to the future, you bypass the AI’s tendency to be agreeable. Here is a breakdown of the mechanics:
- Temporal Shift: By stating “Imagine it is 6 months from now,” the prompt breaks the model’s standard linear prediction mode. It forces a simulation of a specific future state rather than just generating generic advice.
- Definite Failure Condition: The prompt doesn’t ask if it might fail; it asserts that it has failed. This constraint removes the AI’s hesitation to criticize. It must justify the failure, which extracts the most critical vulnerabilities in your logic.
- Constrained Output: Asking for the “3 most likely reasons” prevents the AI from hallucinating unlikely edge cases. It focuses the computational power on high-probability risks.
Variations to Try
The community offered some great ways to sharpen this tool even further. One savvy commenter, u/aletheus_compendium, noted that generic models might give generic critiques. To fix this, you should inject a specific persona.
Variation 1: The Expert Critic
Add a role at the beginning of the prompt to tailor the feedback. For example:
“Act as a senior logistics manager with 20 years of experience. Here is my project plan…”
Variation 2: The Devil’s Advocate
If you want to test the strength of your prevention plan, you can chain the prompt:
“Now that you have identified the 3 reasons, critique my proposed solutions for them. Are these solutions realistic given a limited budget?”
Use Cases 🔮
- Software Development: Paste your feature roadmap and ask the AI why the launch failed. It might highlight scope creep or technical debt you missed.
- Marketing Campaigns: Input your launch strategy to uncover why the audience didn’t convert.
- Personal Goals: If you have a diet or savings plan, ask the AI why you quit after three weeks. It will likely point out that your plan was too restrictive or lacked flexibility.
This approach is a fantastic way to bring a level of objectivity to your work that is usually hard to get without hiring an expensive consultant!

Frequently Asked Questions
Q: How can I stop the AI from giving me generic feedback?
One sharp suggestion from the comments is to assign an "expert role" to the AI before running the prompt. Instead of just asking GPT, tell it to act as a "logistics pro" or "senior designer" to ensure it evaluates your plan within your specific niche.
Q: Why is the "Pre-Mortem" approach better than a standard review?
Most project plans naturally ignore the user’s biggest doubts or potential pitfalls. By forcing the AI to imagine the project has already failed, you trigger "anticipatory reasoning," which helps you spot and prevent expensive mistakes that a standard review might gloss over.
Q: Can I use this prompt for fields other than Project Management?
Absolutely. As noted by users, you can tailor this to any industry by specifying the expert persona (like a designer or engineer). This helps the AI identify technical or creative failure points that are unique to your field, rather than just general management issues.
