Answer:
Motivate them.
Explanation:
Peter Drucker's version is management by objectives, in which the concept was to engage the employee's intrinsic motivation.
So for any manager that's going by this model, the main idea for him is to let the employees know the company objectives, let him embrace the objective as if it were his own and then seek to motivate them.
This motivation can come in the form of monetary remuneration, vacations, bonuses, etc.
