    The Enterprise Architect as a Crisis Manager
    (INFORMATIK 2020, 2021) Breithaupt, Carsten; Vieracker, Jonas; Chircu, Alina; Cox, Sean; Sultanow, Eldar
    In this paper we argue that the Enterprise Architect (EA) should be considered as a crisis manager. In times of a crisis organizations must create a holistic view on the situation and evaluate the proposed measures. Evaluation will be based on experience, data, upfront-created scenarios and assessments of risks, cost and benefits. The EA is already engaged in processes such as Continuity Management, Risk Management, IT Security, Business Process Management, IT Strategy, and others. Therefore, we propose that the EA is one good candidate (not the only one) for handling organizational crises. This paper presents a model of overall crisis management that incorporates an enterprise architecture view as well as related dimensions of crisis management: the ability to control a crisis, the level of communication during and after a crisis, the type of change brought by a crisis, the crisis' outcomes, its distribution within an enterprise, and an organization's criticality of business functions. Finally, we highlight how the EA role supports crisis management at Lufthansa, a top German aviation company.

    A Reference Architecture for On-Premises Chatbots in Banks and Public Institutions
    (INFORMATIK 2021, 2021) Koch, Christian; Linnik, Benjamin; Pelzel, Frank; Sultanow,Eldar; Welter, Sebastian; Cox, Sean
    Chatbots have the potential to significantly increase the efficiency of banks and public institutions. Both sectors, however, are subject to special regulations and restrictions in areas such as information security and data protection. The policies of these organizations therefore, in some cases, reject the use of cloud and proprietary products because in their view they lack transparency. As a result, the implementation of chatbots in banks and public institutions often focuses on open-source and on-premises solutions; however, there are hardly any scientific guidelines on how to implement these systems. Our paper aims to close this research gap. The article proposes a reference architecture for chatbots in banks and public institutions that are a.) based on open-source software and b.) are hosted on-premises. The framework is validated by case studies at TeamBank AG and the German Federal Employment Agency. Even if our architecture is designed for these specific industries, it may also add value in other sectors – as chatbots are expected to become increasingly important for the practical application of artificial intelligence in enterprises.
