What this means is that a good manager will farm work out all over the place finding the right mix of quality / quantity / price.
People will not be paid salaries, they will be paid per unit of work.
Rather than interviewing people to join your family, businesses will be running a continual review of work producs and more carefully measure that mix of quality / quantity / price. Each cycle letting go the least desirable contractors and giving new contractors a try.
On-boarding new contractors will be streamlined, and how fast the contractor gets started will be the first quality control checkpoint.
