Another bloggeriffic Monday.

Take two perfectly equal programmers. Sit 'em down at laptops with a Net connection. Give them each the same two projects.

Programmer A works (let's be reasonable) seven hours a day for a week for two weeks. Make Programmer A work on Project 1 the first week and Project 2 the second.

Programmer B works (let's continue to be reasonable) seven hours a day for a week for two weeks. Make Programmer B work on Project 1 the first half of each day and Project 2 the second half.

Guess who's further along, in my anecdotal experience, at the end of two weeks? That's right! Programmer A. As the number of projects goes up, the difference becomes more pronounced.
