       | What is an O-ring in this situation? I was expecting an article
       | on sealing but this has me confused.

         | 
         | The name is a reference to the Challenger disaster, which was
         | caused by a failure of actual sealing O-rings, but the theory
         | itself is abstract.
         | 
         | Basically, it's modeling complex production chains where the
         | quality of the "weakest link" is the limiting factor of the
         | quality of the whole process.

           | So a multivariate Laffer curve?

             | Completely unrelated. Laffer curve is total tax returns as
             | a function of tax rate (usually used to show that at some
             | point T = t*Y(t), where t is the rate and Y is the taxe
             | base, dT/dt < 0).
             | 
             | This is about how Y works, not as a function of t but of,
             | well, everything else.

           | OK, but isn't the key take-away from the Challenger disaster
           | all about the consequence of organizational dysfunction and
           | fear of speaking up?
           | 
           | It wasn't really a "design flaw" or "weak link" as much as it
           | was management disregarding the warnings of engineering
           | staff. The cold temperature limitation was known in advance
           | by the Morton Thiokol engineers but their management refused
           | to relay the warnings of engineering to NASA and NASA was
           | under pressure to fly. IMHO this was a failure of multiple,
           | mostly organizational, systems rather than "one weak link".
           | 
           | Did the economists mis-name their own theory?

             | Likely yes, because NASA and other agencies were able to
             | portray the incident as an O-ring failure. It was in fact
             | just that management was indifferent to the risk to the
             | astronauts on board. The only individual who accurately
             | reported on the disaster was Feynman.

             | The o-ring was still the weak link, a small part that
             | decision makers assumed was insignificant whose failure
             | caused the complete destruction of a massive system and
             | tragic deaths. The organizational failures are just why the
             | weak link wasn't addressed. We can say with hindsight that
             | things should have been better communicated and the
             | warnings should have been heeded, but the fact is they were
             | dealing with a complex system where the risk was
             | sufficiently non-obvious that they could disregard the
             | warnings.

         | Richard Rumelt has a nice article about this:
         | 
         |  _> The strength of a chain depends on the strength of its
         | weakest link. When activities have chain-link logic, the
         | strength of the weakest, or least efficient, part limits the
         | performance of the whole. Thus, a solid rubber O-ring was the
         | weakest link for the Space Shuttle Challenger. Falling out of
         | the winter sky in 1986, it shattered onto the ocean below,
         | killing the crew President Reagan called "pride of our nation."
         | For the Challenger, making the booster engines stronger or
         | improving its communications systems would be foolish
         | investments if the O-ring remained weak._

       | Nothing in the article about targeting the rate-limiting factors.
