Managing Director

Master in Data Analytics & Management

The abundance of data in combination with technologies such as machine learning is a rapidly changing business. Initially companies tend to focus on the technical challenge but often it’s actually the strategical and organisational challenge that turns out to be bigger. The Master in Data Analytics & Management will give you the skills to understand the technical foundations of digital transformation, driving strategic and business model implications and managing the necessary organisational change aiming at a purpose-driven and sustainable business transformation.

Taught class: IoT

Bachelor in Computational Business Analytics

Business Analytics is concerned with the development and application of quantitative approaches to support managerial decision-making. Experts in this domain are familiar with different methods for data collection and acquisition. They can analyse data and build statistical models, and they can translate the outcomes of data analyses to actionable recommendations for managers. On top of this, they need to have a thorough understanding of the different areas of management, including accounting, finance, marketing and operations.
