A lot depends on the correct organization of any production or office, and not only labor productivity. But also the moral climate in your team. The result of the right organization will be that each employee will do their job with maximum efficiency, the team will have a spirit of mutual assistance and understanding of common goals.
Fully study the entire technological chain of your department's work from what comes in and what should come out of it. Make yourself a very clear idea of this and think about what personnel and organizational solutions will be optimal for the fulfillment of the task set before you.
Study your employees. There are clearly defined psychological types of people for whom psychologists have given definitions and recommendations, what kind of work they are able to perform with maximum efficiency and what can be expected by entrusting them with a task. Determine for yourself the capabilities of each, think about what personal qualities you can use to benefit your work - purposefulness, accuracy, healthy careerism, scrupulousness, etc.
Combine this knowledge and entrust everyone with exactly that front of work where he will be most useful and work on which will bring him pleasure. Work doesn't have to be hard labor, although for some it is. Only creative work, awareness of the importance of the work being performed and the encouragement of the success achieved by a person can become an incentive for his further professional development.
Explain to everyone his task, his area of responsibility, and what you expect from him in the end, but at the same time, do not forget about mutual assistance and interchangeability of employees, so that illness or absence of one will never become the reason for the inhibition of a well-oiled work process.
Unite your employees into a single team, explain the importance of the task assigned to the department, note how much it depends on the labor input of everyone, maintain a healthy team spirit in the team.
Never forget to reward employees, and do it publicly. But it is better to lecture in private. Don't make favorites and favorites, such unhealthy rivalries never lead to good ones. Maintain normal companionship in your team. Much of the work of the department depends on you.
