Sensing Social Media for Corporate Reputation Management: A Business Agility Perspective

In: Proceedings of the 20th European Conference on Information Systems (ECIS); Barcelona, Spain

Category: Proceedings

Abstract

The concept of business agility reflects an organization’s need to develop sensing capabilities for being able to respond to changes in the business environment rapidly. Therefore, intelligent information systems are needed to support decision makers with accurate and timely information. Since corporate reputation is among the most valuable assets, organizations need efficient measuring techniques for being able to manage it. Recently, due to the advent of social media new reputational challenges have emerged for firms, since such technologies significantly increase the risk for being associated with negative issues. Therefore, organizations should utilize there IT-systems for actively sensing social media content as a basis for a quick response to reputational threats. Accordingly, we provide an empirical example on how firms might improve corporate reputation management through sensing social media. Specifically, we analyze a dataset of 271,207 messages about a large American Bank collected from the public microblogging platform Twitter. For our empirical investigation, we applied automated sentiment analysis and manual content analysis. Our results demonstrate how social media might impact corporate reputation and what organizations can do to prepare themselves. Beyond corporate reputation management, analyzing social media content may be valuable for many other purposes to improve an organization’s sensing capabilities.

Searching for Answers - Knowledge Exchange through Social Media in Organizations

In: Proceedings of the 45th Hawaii International Conference on System Sciences (HICSS 2012); Winner of the BEST PAPER AWARD; Maui, Hawaii, USA

Category: Proceedings [Find it]

Abstract

Organizations need information systems that facilitate the exchange between knowledge seekers and contributors in order to manage knowledge successfully. As prior research suggests, social media platforms are a promising solution for bridging the gap between both sides in an effective manner. To enhance our understanding of the benefits of these technologies for knowledge management, we analyze the content of 15,505 enterprise microblogging messages created by 1,166 employees of a major international bank. Specifically, we explore what kind of knowledge users seek and how knowledge is contributed from an individual perspective. Building upon social capital theory we further analyze how the strength of the relationship between seekers and contributors influences the quality of knowledge exchange. Our results provide first insights on how knowledge exchange through social media takes place in organizations. Moreover, we find empirical evidence that these technologies leverage an organization’s existing knowledge, specifically through bridging of otherwise disconnected people.

Kundenloyalität bei Bankdienstleistungen: Cross-Buying im deutschen Privatkundengeschäft [Customer loyalty in banking: cross buying on the German retail market]

In: Betriebswirtschaftliche Forschung und Praxis (BFuP); forthcoming

Category: Publications in scientific journals

Abstract

Ein wesentlicher Treiber für den Kundenwert im Bankgeschäft ist der Kauf zusätzlicher Produkte durch den existierenden Kunden, das sog. Cross-Buying. Insbesondere bei den Finanzdienstleistungsprodukten profitiert dabei der Absatz von Folgeprodukten von einer starken Bindung des Kunden an das Unternehmen. Erschwert wird die Analyse durch den gleichzeitigen mehrfachen Produktbesitz bei unterschiedlichen Anbietern. Die in diesem Beitrag vorgestellte Erweiterung des Brand-Switching-Modells von Colombo/Morrison erlaubt neben der Beurteilung der Cross-Buying-Loyalität von Bankkunden daher insbesondere die Einbeziehung halb-loyaler Kunden auf Basis von extern verfügbaren Marktdaten. Mit empirischen Daten zum deutschen Privatkundengeschäft in den Jahren 2006, 2007 und 2008 wird der Einsatz des Modells für die Cross-Buying-Produktsparten Geldanlage und Bausparen demonstriert.
