Wisdom knows what to do. Next, skill is knowing how to do it, and virtue is doing it. - David Star Jordan
From theory to actual practice, motivation strategies are essential. Though applying which approach to use is tricky, practicing each varies depending on its application and to whom you are applying it, in this case, the employees.
Do they respond to praises and appreciations? Do they tend to react? Flexible hours and a casual dress code? To structure and advertise rewards related to performance?
Try understanding each theory by applying it to the workplace. You can try evaluating them and see which approach best works for the workplace and the employees.
