Multisided platforms are new organizing forms that can boost innovation in the healthcare sector by empowering patients as innovators and facilitating the commercialization of innovations by and for patients. However, applying the playbook script for the platform model from other sectors may prove challenging given the distinctive nature of the healthcare services. Drawing on the case of a leading healthcare innovation platform in Europe, this article examines the platform's role in identifying and enabling the development and diffusion of patient innovations. This involves three main roles (community organizer, market matchmaker, and innovation manager) and corresponding orchestration activities.

The diffusion of digital technologies has enabled a notable transformation in the firms' boundaries, processes, structures, roles, and interactions. It is now clear that digital transformation is not just a traditional IT back-end process; rather it affects the organization as a whole, redefining strategies, entrepreneurial processes, innovation, and governance mechanisms. This permeation has led to the emergence of new ways of organizing firms' value chains and interfirm relationships, which now increasingly occur in digital ecosystems and marketplaces. The scope of transformation as well as the modalities of value co-generation and delivery are here used to introduce the content of this Special Issue of California Management Review on Digital Transformation.

Governing a city is arguably one of the most complex management tasks facing organizational leaders. Based on an analysis of Vienna, London, and Chicago, this article demonstrates that city leaders treat cities as ecosystems, structured and governed either as "extended enterprises" where inputs from specialized organizations are coordinated and integrated into the final service or as "platform markets" where direct interactions between third-party service providers and citizens are facilitated by the city leaders. If cities are viewed as the "ecosystem of ecosystems," then successful city governance requires an orchestration approach where leaders choose the appropriate structure and manage the ecosystem dynamically in a constantly changing environment.
