Software developed by XIMES: The Operating Hours Assistant (OPA)

Calculate personnel requirements professionally and quickly

Suitable services for every need in the shortest time!

Working time management is aimed at systematically matching personnel requirements with the personnel capacity deployed. For this purpose, the need for seasons, fluctuating workload, qualifications, ... must be easy to present and discuss since often a negotiation process is required. On the other hand, there are varieties of working hours and staffing levels of how to cover demand in the best possible way, depending on legal requirements (e.g. maximum lengths for services), ergonomics (e.g. earliest possible start of service, average number of working days per week), administration (e.g. number of different types of service) and the minimisation of over- and under-coverage for the purpose of economic efficiency.
