開放原始碼軟體平台與互補性資產建構—以Google與 Intel 為例 / Open source software is Open Innovation only if it has a business model driving it (West and Gallagher 2006). Open Innovation is the paradigm describing the scenario in which firms use a broad range of external sources for innovation and seek a broad range of commercialization alternatives for internal innovation (Chesbrough 2003). The Platform Leader builds the platform and concentrates its efforts on promoting and directing innovation of complementary products in favor of its R&D direction (Cusumano and Gawer 2002). The author has chosen leaders in two distinctive industry sectors— Google, the leader in search engine industry, and Intel, the leader in the microprocessor business for the personal computer industry—as the case study companies for this research. Both cases fit the definition of open innovation since both Google and Intel have specific business models for their open source software platforms. This research explores how industry leaders exploit open source software platforms to realize their specific strategic intents. The research problems are: (1) how companies can incorporate external creativity and innovation to maintain their own innovative momentum; (2) what are the key factors and strategies for building a successful open source software platform and its ecosystem; (3) how can a company use an open source software platform as part of its strategy to enter new markets and promote development of complementary assets to build its competitive advantages. The author proposes the following framework to analyze how leading firms design open source platform strategies: (1) analyze the firm’s core competencies; (2) analyze the firm’s strategic intent for their open source software platform; (3) analyze the firm’s strategies for designing the architecture of their open source software platform; (4) analyze the firm’s strategies for designing the ecosystem around the platform. Based on the analysis of the two comparative cases, the author has been convinced of the following propositions: 1. Firms can use open source software platform to incorporate external creativity and innovations that promote the development of complementary assets and to build or at least maintain their competitive advantage against competitors. 2. Instead of a purely open or purely proprietary platform strategy, platform owners can utilize a hybrid strategy, which combines the advantages of open source and closed source to retain control and differentiation. 3. As opposed to a company-owned open source software platform, a community-owned open source software platform will attract more communities’ involvements and stimulate more innovation. 4. When developing complementary assets, firms should adopt an open innovation approach to incorporate external creativity and innovations; however, when building their core competencies, firms should adopt a more closed innovation approach to maintain their distinctive competitive advantages. 5. One of the key determining factors of a successful open source platform strategy is the platform owner’s ability to create value and enable every partner within the ecosystem to share some portion of it.
