A project manager finishes a Murphyjitsu session for a product launch. She has gone through the plan step by step, identified three failure modes, and modified the plan to address each. The plan now 'feels like it will work' at every step. What should she do next?
AShe should run at least five more iterations regardless, because gut checks are unreliable
BThe session is complete — the plan has passed the gut check and is ready to proceed
CShe should create a formal risk register to document all identified failure modes for stakeholders
DThe gut check is only valid for short-term plans; long-term plans require external review
Murphyjitsu concludes when the plan passes the gut check — when each step feels like the kind of step that will work. The gut check is the stopping criterion, not an arbitrary number of iterations or a formal documentation requirement. The key insight is that the gut check reflects System 1's pattern-matching judgment that identified failure modes have been adequately addressed.
Question 2 Multiple Choice
Which of the following best describes how Murphyjitsu differs from a standard premortem?
AA premortem uses imagined future failure; Murphyjitsu uses historical data about past failures
BMurphyjitsu adds an iterative repair loop — after identifying a failure mode, you fix it and repeat the gut check until the plan passes
CMurphyjitsu is only used for short-term personal plans, while premortems are for organizational projects
DA premortem assigns probabilities to failure modes; Murphyjitsu treats all failure modes as equally likely
Both techniques involve imagining failure before it occurs. What distinguishes Murphyjitsu is the iterative repair loop: you identify a failure mode, modify the plan to address it, then ask the gut-check question again. You repeat — identify, fix, check — until each step passes. A premortem typically lists failure modes for awareness, but does not structure the process as iterative plan improvement until a robustness threshold is met.
Question 3 True / False
Murphyjitsu recommends systematically identifying and addressing most conceivable failure mode in a plan before proceeding.
TTrue
FFalse
Answer: False
Murphyjitsu is specifically scoped to failure modes that your gut flags as realistic — those System 1 identifies as the kind of thing that would likely go wrong. It is not a comprehensive risk audit. The technique explicitly does not require fixing every possible failure mode, only the ones that feel realistic enough to trigger a failed gut check. This scope keeps the technique practical and prevents paralysis while still catching the most likely failure points.
Question 4 True / False
Murphyjitsu leverages System 1 (intuitive pattern-matching) to detect plan weaknesses that explicit reasoning may have overlooked.
TTrue
FFalse
Answer: True
This is a core feature of the technique. Explicit System 2 reasoning may construct a plan that looks coherent on paper but still 'feels off' because intuition, shaped by experience, has pattern-matched it to previous failures. Murphyjitsu uses this gut reaction as a signal: if a step feels like it will fail, that feeling is worth interrogating even if you cannot immediately articulate why. The goal is to surface implicit concerns and convert them into explicit fixes.
Question 5 Short Answer
What does Murphyjitsu add beyond a simple premortem, and why does that addition matter for the quality of plans?
Think about your answer, then reveal below.
Model answer: A premortem generates a list of failure modes; Murphyjitsu adds an iterative repair loop. After identifying a failure mode, you modify the plan to address it, then run the gut check again. This continues until every step passes. The addition matters because awareness of a failure mode without plan modification does little to prevent it — Murphyjitsu produces an actually improved plan, not just a list of risks.
The name captures this: jujitsu uses the opponent's force to strengthen yourself rather than merely bracing for impact. Murphyjitsu takes Murphy's Law — whatever can go wrong will — and instead of treating it as a warning, uses it as a tool to iteratively strengthen plans. The iteration stops at the gut-check threshold, making the technique bounded and practical rather than an infinite risk-cataloging exercise.
