Mario Rosenfelder

Mario Rosenfelder is managing director of consultnetwork GmbH and an expert for integrated management control.


Mario Rosenfelder, business economist (MBA), has studied controlling and strategic business management at the Alpen-Adria-University and completed the strategic management for executive’s education at the renowned St. Gallen Business School.

Today Mario Rosenfelder is the managing director of consultnetwork GmbH and expert for integrated management control. As such he has been designing and implementing solutions for the integrated management of companies and groups of companies for more than ten years. An important part of the controlling strategy concept developed by Mario Rosenfelder is the provision of integrated reporting solutions according to the ONE PAGE principle. The ONE PAGE reports follow the report design of the IBCS® Standards and consider a control loop for integrated corporate control. The implementation of the IBCS® Standards and the ONE PAGE principle is based on a 5-step model, which has been tested and refined in numerous projects (reference project: Gabor)

Mario Rosenfelder acts as speaker and trainer in front of entrepreneurs or controllers on various controlling topics. He also runs the extremely successful YouTube channel ‘controlling-strategy’.

IBCS® Certified Consultant

Mario Rosenfelder has successfully completed the IBCS® certification for successful design of reports and presentations at the HICHERT+FAISST IBCS Institute in February 2020.

Work samples

The first part of the two-part video series describes what the IBCS® Standards regulate regarding stacked columns.

The second part shows how comparison of planned/actual data can also be implemented with stacked columns. This topic is of particular importance to consultnetwork, as one of our main focuses is the conception of reports according to the ONE PAGE principle, which our certified employees and colleagues also technically implement with BI tools like Cubeware, Truechart, Microsoft Power BI or SAP Analytics Cloud. A central element is the summarized display of various information relevant to a control task and also the representation of a control loop, which always requires a comparison of planned/actual data. The use of stacked columns makes perfect sense due to the high information density, but can only provide a relevant input to management if a corresponding comparison of planned/actual data is also possible. Therefore, we have dealt with the comparison of planned/actual data for stacked columns, which is viewed quite critically in the IBCS® community, and show possible solutions that enable the comparison of planned/actual data.
