To profit from crowdsourcing, organizations can engage in four different approaches: microtasking, information pooling, broadcast search, and open collaboration. This article presents 21 governance mechanisms that can help organizations manage their crowdsourcing platforms. It investigates the effectiveness of these governance mechanisms in 19 case studies and recommends specific configurations of these mechanisms for each of the four crowdsourcing approaches. Also, it offers guidance to organizations that host a crowdsourcing platform by providing recommendations for implementing governance mechanisms into their platforms and building up governance capabilities for crowdsourcing.

Meditec is a German manufacturer of instruments for surgeries. The company is quality leader in this sector and supplies many German and international hospitals. However, the opportunities for differentiation against competitors decrease continuously. New competitors from emerging markets are challenging the market position of established companies in this industry. Meditec is therefore forced to change its strategy and business model in order to survive in this novel competitive environment. The management of Meditec has decided to traverse from a pure product manufacturer to a customer-centric solution provider. This transformation requires the development of new processes, competencies and capabilities - especially with respect to IT and IT services. This teaching case helps in understanding the role of IT in product-service systems (PSS) and PSS-based business models. Therefore the case illustrates why IT is necessary to establish a PSS-based business model and why a customer-centric view is important for this kind of business model.

Mergers, acquisitions and divestments, including the carve-outs of business units or parts of them, are standard strategies used by multi-divisional organizations to adjust their business portfolios. Carve-out projects are critically dependent on their management of IT. Systems, which have been integrated in order to deliver seamless and efficient IT operations, must now be pulled apart under demanding time and compliance constraints. In 2007, Delta IT Consulting (DIC), one of France's biggest IT-service provider, sold one of its three service provider divisions, IT Product Services. This division employed about 3500 employees in 20 countries and previously generated 0.7 billion of DIC's euro3.8 billion revenues. DIC itself is a division of Delta Corporation - a French high-tech company and leading player in a wide array of businesses, industries and countries around the world. This teaching case challenges the reader to analyze and manage the IT carve-out as a critical component within the divestment project. The case includes insights into strategic and organizational challenges of planning and managing an IT carve-out project.

As IT innovations in the last years emerged on the consumer market, employees are more experienced in the private than in the corporate use of innovative IT devices and applications. These employees, familiar with the benefits consumer products offer, expect those to be provided by their corporate IT. This trend, referred to as 'consumerization of IT', leads to more and more consumer innovations infiltrating companies. In particular, mobile consumer devices are currently spreading into companies, strongly pushed by top management, and create several challenges to Chief Information Officers (CIOs) around the globe: 'What IT costs are associated with the use of mobile consumer devices?', 'How will corporate use of mobile consumer devices affect IT management?', and 'How to introduce an IT service for corporate as well as personal mobile consumer devices?'. OMEGA Group, a multi-national company with 50,000 employees, wants to leverage the potential of mobile consumer devices for corporate purposes. Therefore, these questions have to be addressed and answered by its CIO. The teaching case is designed to introduce the characteristics of consumerization and associated challenges for IT management. The case uses selected information systems methodologies and frameworks.
