Designing working time models

The right working time model for your requirements

Whereas most companies are in line with the times when it comes to their manufacturing processes and their product mix, and perform meticulous analyses and optimization, their shift or duty rosters often remain unchanged. Demand peaks are simply compensated for by expensive additional shifts or the use of temporary workers, while overstaffing is tacitly accepted. Working time models, however, should also be analyzed from time to time and adapted to new conditions, just like the vertical range of manufacturing, product and variant diversity or machines and systems. After all, this also has a significant impact on efficiency and value creation. But just how does one go about developing an optimal working time model?


Five steps to an optimal working time model

  1. How much capacity is required?
    In order to develop an optimal working time model, or an ideal shift or duty roster, the first step consists in determining the required manufacturing capacities, while taking the possible plant capacities into account. Therefrom it is derived to what extent and over what period of time the personnel capacities are required. Moreover, the required flexibility of staffing time and staffing levels are defined.
  2. How many employees are needed to meet the personnel requirements?
    The personnel actually required can be calculated on the basis of the staffing requirements, whereby planned and unplanned absences (for example, due to vacation or illness) are also factored in. This second step also comprises an initial calculation of the additional and reduced costs compared to the current total personnel costs.
  3. How must the shift plan be structured?
    Depending on the required flexibility of the staffing time and staffing levels and the staffing requirements, the parameters are defined in order to adequately structure the duration of the duty schedule and shift cycle. Moreover, the frequency of each shift in the cycle is determined.
  4. How is the shift plan designed in detail?
    As soon as the framework of the new duty schedule parameters is established, the individual shifts are distributed over the weeks and weekdays of the schedule, additionally extended by possible substitute shifts. Here, the main focus is on taking seasonally fluctuating staffing requirements into account.
  5. How are employees assigned to the shifts?
    Individual employees are assigned to predefined shifts in the duty schedule. On this basis, any additional personnel requirements can be derived. Finally, the new duty schedule is compared with the shift plans of other areas in order to ensure material flows.
