The Business Innovation Kit (www.facebook.com/businessinnovationkit) and related tools (Strongly Sustainable Business Model Canvas, Stakeholder and Value Mapping) enable entrepreneurial teams to explore the range of ideas and viable business models for a new or existing business. The “Business Modeling Starter Kit” (Breuer 2013) highlights the normative foundations of business through an initial exercise called “grounding”. Starting into the process, participants create a common ground for their endeavour by explicating their fundamental goals and values. With respect to sustainability, business model patterns are used to stimulate thinking in terms of particular models and model elements; e.g. the two patterns “substitute with renewables and natural processes” and “repurpose the business for society and environment”. Stakeholder segments as a basic component and “challenger cards” serve as an initial check of new business model assumptions.
