Decision Making

Decision-making processes and its results can be improved by including affected stakeholders. Both legitimacy and acceptance could be increased. The communicative potential of the internet offers numerous opportunities to get those affected involved. At the DIID, these possibilities as well as the problems and challenges of online decision-making processes are analyzed, modeled and tested in different environments


  • Formal modeling of online participation processes

  • Internet-based decision-making in a business context

Formal modeling of online participation processes

Formal models of theoretical computer science for describing and evaluating the interactions of actors in online participation processes and their outcomes

  • What criteria can be set for the quality of different online participation processes and their outcomes?
  • How do classical argumentation models have to be extended to reflect the dynamics of real argumentation in online contexts?
  • How can dynamic scenarios or scenarios with uncertainty be modeled?
  • What algorithmic configurations do such online participation models have?

Internet-based decision-making in a business context

Quality, effects and legitimacy of internet-based economic decision-making processes in private companies, interest groups and advisory boards as well as NGOs.

  • How do internal decision-making and controlling processes on the basis of online communication affect decision-making behavior, compliance and interaction?
  • How does online communication in interest groups change opinions, decision-making and participation compared to alternative decision-making mechanisms?
  • What effects does online decision-making on regulation issues have on the effectiveness, legitimacy and acceptance of the results?
  • Which systematic decision distortions (biases and framing) can accrue in internet-based decision-making processes in economic contexts?

Jun.-Prof. Dr. Dorothea Baumeister is a junior professor for computational social choice at Heinrich-Heine-University in Düsseldorf. Since 2017 she leads the DFG-project “Distances in Voting”.

In her research she concentrates on the axiomatic and computa tionalan  alysis of problems from the field of preference aggregation, votingsystems, and fair division. At the DIID her focus lies on the mathematical formalization of processes in online participation and theinfluence of distances in online voting.

Prof. Dr. Barbara E. Weißenberger

Board, Business Administration

Prof. Dr. Barbara E. Weißenberger holds the Chair of Accounting in the Department of Business Administration and Economics at Heinrich Heine University Duesseldorf. She is also Affiliate Professor of Accounting at Bucerius Law School, Hamburg.

In her research, she is most interested in how management control system design affects managerial decision-making with respect to firms’ financial objectives as well as non-financial goals, e.g., compliance or ecological and social sustainability. At the DIID, she studies the impact of the digital transformation in firm’s business models as well as within the finance function on these issues.
