Your Task

The main driver for this service is to reach a consistent state of documentation, where all devices within approximately 8,000 central offices ("Betriebsstelle") will be sufficiently mapped. With this mapping, much improved cost efficiency within energy and space management will be achieved. This will directly benefit the central overview about technical equipment rack-slots including documentation of technology and energy supplies. This is a critical pillar for an overall energy management strategy and therefore contributes to the corporate objectives for carbon dioxide emission reduction.

This role is the main enabler for transparent space utilization, energy consumption and energy planning, managing technical places, and localization of undocumented legacy systems.
