How do you get others to do what you want them to do? Generally people and companies motivate with some combination of fear, punishment and material reward. "Do this or else," couched in some more politically correct way is most often used. The "or else" can be a negative consequence and/or the threatened loss of monetary reward, employment, or positive attention.
We also use this aversion-attraction technique on ourselves, reprimanding and threatening ourselves with self criticism to try to get us moving, or promising ourselves some reward/special treat unrelated to the project we are working on.
