### Transcript

• 1. Why do things go wrong? Kshitij Varma
• 2. Is it just plain bad luck?
• 3. Or Murphy at Work?
• “ Anything that can go wrong, will go wrong”
• 4. The Genesis
• The “ Gee Whiz ” test to simulate the force of an airplane crash (1949, Edwards Air Force Base, California)
• Colonel John Paul Stapp – Volunteer for the test & Murphy’s Boss
• Captain Edward A. Murphy Jr. – An engineer in the airforce
• “ Whatever can go wrong, will go wrong” makes it to the press
• 5. Extensions of Murphy’s Law
• The first 90% of a project takes 90% of the time, the last 10% takes the other 90% of the time.
• If you are good, you will be assigned all the work. If you are really good, you will get out of it.
• Never ask two questions to an expert. The reply will discuss the one you are least interested in, and say nothing about the other.
• Anyone can make a decision given enough facts.
• A good manager can make a decision without enough facts.
• A perfect manager can operate in perfect ignorance.
• 6. Method to the madness? P M  Murphy’s Probability K M = 1 F M = 0.01 I  Importance of the Result C  Complexity of the system U  Urgency of the need F  Frequency The Toyota Tercel test (1989) I = 8 C = 5 U = 8 F = 1 P M = 1
• 7. Murphy & Me at IIT
• In order to get a loan you must first prove you don't need it
• Beauty times brains equals a constant
• The moment you have worked out an answer, start checking it -- it probably isn't right
• The only PPTs that start on time are those that you're late for
• The other line moves faster
• Corollary - Don't try to change lines. The other line -- the one you were in originally -- will then move faster
• 8. Negating Murphy – Idiot Proofing
• 9. Have we seen the last of Murphy?
• Make something idiot-proof, and they’ll build a better idiot! (O’Toole’s Law #1)
• Murphy was an optimist! (O’Toole’s Law #2)
• 10. Thank You Your Queries are welcome
