In a knowledge economy, am I measured by ideas per minute? That’s silly. It makes perfect sense to measure a field worker in bushels per hour, but in the emerging network economy, the measurement problem has become profound.

People are saying, look, we’re in an era of enormous uncertainty because we can’t even measure what’s going on.
