Christoph, Great ideas. Many definitions of social business do not focus on capturing the evolution of business such as the one you have described here. When it comes to social business, we are talking about the evolution of business that is triggered or enabled by social technologies like social computing, social media, social product development. For instance, machines helped us produce more. From handmade, cottage industry, businesses have evolved to become mechanized and automated mass-producer. When Internet arrived, it helped us digitize our business. From automated mass producer, businesses have transformed into digitized mass producer or e-business. Similarly, there is a business impact of social media, which I think can be defined with the answers for these two questions: "For whom to produce?" and "How to produce?". Instead of "producing more products for one or two stakeholder groups like customers", today businesses have to "produce more products or value for many stakeholder groups which could include local community as well". This happens because social media is an open platform where people representing different stakeholder groups are taking part, interacting and they have different expectations from a business. So, it is not produce more products but produce for more stakeholders. Then, there is the question of how to produce? Internet enabled us to digitize our business, social media is helping us to democratise our business, where all business processes - including product conceptualization, management, to marketing - are being made open for the participation of the society. We are already seeing the success of social product development, and open innovation. So, the definition should be made on these lines of what Prof C K Prahalad said of the emerging role of economy/industry: a social business "is run by, of, and for people" or something like that which captures the factors: "producing value for more" and "democratization".
