Efficiency improvements in corporate processes are crucial for sustainable and environmentally conscious use of available resources, so that future generations can also benefit. While many studies highlight the importance of product innovations, there are few that investigate the direct relationship between process innovation and company performance. The main goal of the research project is to identify the extent to which process innovations, leading to efficiency gains, have a positive effect on company performance. In the research project, efficiency gains are quantified through a Data Envelopment Analysis (DEA). The resulting process efficiency is expected to explain part of the company's growth and future performance. Various DEA models will be identified, developed, and tested for measuring process innovation. The project aims to build on previous research, particularly by Hörler and Brecht (2023), to develop practice-relevant applications for the economic landscape of Liechtenstein. The research project makes a significant contribution to science by extending DEA-based efficiency measurement to process innovations. It aims to demonstrate the extent to which efficiency gains can improve company performance and identifies patterns that distinguish efficient from less efficient companies. For the efficient companies, Best Practice Cases can subsequently be derived.
