During my work as an engineer I learned that once you assign a second project to someone, his productivity drops by 50%. So, if the two projects took a month separately, doing them in parallel would take four months instead of two.

Applying this rule to the directors problem, it would mean that a director who switches between two jobs would be four times less effective compared to a full-time one.

Bearing in mind that the 50% rule is exponential, you can make your own conclusion how effective a director who serves on 4 or 5 boards (not uncommon) could be.
