The following are some reasons why one should follow the key figure in management:

1. Cost monitoring: The key figure provides insights into the total labor costs for all work orders and maintenance actions. It is important to control and manage the total operating costs of properties and facilities.

2. Resource planning: By tracking logged hours, property management can plan and allocate human resources efficiently to manage work orders and projects. It helps ensure that the right amount of staff is available when needed.

3. Efficiency assessment: The key figure gives an idea of how efficiently work orders are handled. High total hours logged may indicate inefficiencies in the work processes that need to be addressed.

4. Quality control: It can be used to evaluate the quality of work performed. If logged hours are high, it may indicate problems with work performance or the need for additional training and resources.

5. Benchmarking: By comparing logged hours over time or with other property managers, best practices and areas for improvement can be identified.

6. Budget planning: The key figure helps estimate and plan for labor costs in future budgets and forecasts.
   Performance measurement: It can be used as a performance indicator to assess how well work processes are working and whether there is a need for changes or improvements.

In summary, the key figure provides a comprehensive overview of the workload, cost control and resource use within property management. It helps make informed decisions and improve the efficiency and quality of maintenance operations.
