Pond's Seventh Law, Applied Again

Pond's Seventh Law, Applied Again

[UPDATED 17 August 2007: the first story turns out to be a hoax, which places the second one in doubt as well.  Please consider this a parable rather than a reportage] 

A colleague sent along an email earlier today which, at its root, strikes me as a plea for Pond's Seventh Law, so it seems a good time to make this point again:

Difference between Focusing on Problems and Focusing on Solutions 

Case 1

When NASA began the launch of astronauts into space, they found out that the pens wouldn't work at zero gravity (ink won't flow down to the writing surface). To solve this problem, it took them one decade and $12 million. They developed a pen that worked at zero gravity, upside down, underwater, in practically any surface including crystal and in a temperature range from below freezing to over 300 degrees C.

And what did the Russians do...?? They used a pencil.

Case 2

One of the most memorable case studies on Japanese management was the case of the empty soapbox, which happened in one of Japan's biggest cosmetics companies. The company received a complaint that a consumer had bought a soapbox that was empty. For some reason, one soapbox went through the assembly line empty.  Management asked its engineers to solve the problem. Post-haste, the engineers worked hard to devise an X-ray machine with high-resolution monitors manned by two people to watch all the soapboxes that passed through the line to make sure they were not empty.  No doubt, they worked hard and they worked fast but they spent a whoopee amount to do so.

But when a rank-and-file employee in a small company was posed with the same problem, he did not get into complications of X-rays, etc., but instead came out with another solution. He bought a strong industrial electric fan and pointed it at the assembly line. He switched the fan on, and as each soapbox passed the fan, it simply blew the empty boxes out of the line.

Moral: Always look for simple solutions.  Devise the simplest possible solution that solves the problems

..or, "random elegance that doesn't serve performance and maintainability is no virtue."  Much like Snoopy the dog, I quote the truth where I find it..

  • Reminds me of a funny story. Several years ago a friend of mine was helping with IT for a school and they had a cheap deal for ISDN Internet access from the school network.

    During the day the ISDN call charges were free, but during the evening, over night and weekend they were high.

    The head of the school asked my friend to ensure that the ISDN router couldn't dialup in the expensive times to ensure they didn't run up a large bill.

    He asked me about and being the techie I am, I was straight in with "let's configure access control lists with time ranges". My friend went for the more agricultural solution of buying a power timeswitch and set that to turn the router off during the expensive times. :-)

  • Great story, Charles.  It seems to me we've developed a bias against "crude but effective" solutions which may not, in fact, be serving our best interests.  My guess would be that the school was entirely content with your friend's solution; how many other such opportunities are we missing?
