In the "crazy" world of software development, we are often pushed to make software the best, the biggest, or the option with the most features.
When Boeing prepared to launch the design of the 727 passenger plain in the 1960s, its managers set a goal that was deliberately concrete: The 727 must seat 181 passengers, fly nonstop from Miami to New York City, and land on Runway 4-22 at La Guardia. (The 4-22 runway was chosen for its length--less than a mile, which was much to short for any of the existing passenger jets.) With a goal this concrete, Boeing effectively coordinated the actions of thousands of experts in various aspects of engineering or manufacturing. Imagine how much harder it would have been to build a 727 whose goal was to be "the best passenger plane in the world."
Setting those few important goals helped make the 727 a successful and versatile aircraft. This same concept can be applied to anything we do, even on a much less grand scale.
This is a great reminder to not lose focus on what is important to your project.
Now, back to creating the best software I can :)
