  6. 4. Managing offshoring of complex products : Strategy and capabilities

    Author : Petra Edoff; Christer Norström; Jayakanth Srinivasan; Stefan Cedergren; Peter Ørberg Jensen; Mälardalens högskola; []
    Keywords : Strategy; organizational capabilities; offshoring; product development; India; China; Innovation and Design; innovation och design;

    Abstract : Offshoring is a hot topic in the industrial and academic community over the last few years, evolving from a focus on manufacturing to product development and R&D. Offshoring refers to the process of sourcing and coordinating tasks across national borders and can include both in-house and outsourced activities performed by a supplier. READ MORE

  7. 5. Organizational capabilities for managing the offshoring of product development

    Author : Petra Edoff; Christer Norström; Jayakanth Srinivasan; Stefan Cedergren; Vinit Parida; Mälardalens högskola; []
    Keywords : offshoring; outsourcing; product development; management; culture; TECHNOLOGY; TEKNIKVETENSKAP; Innovation and Design; innovation och design;

    Abstract : Large multinationals must continually innovate to produce products and services that meet the needs of a global market. In order to distribute work across multiple sites, they use techniques such as offshoring and outsourcing. This requires them to address organizational and cultural aspects to coordinate distributed product development activities. READ MORE
