This case tells the story of the Café spurlos which aims at becoming a zero waste business and thus making a significant contribution to combating one of the greatest challenges facing society today: the transformation of the eco-nomic system into a circular economy. Besides the COVID-crisis and the thereof resulting issues, the café also faces challenges related to its vision of incorporat-ing the zero waste philosophy in its concept. The case explores the complexity of zero waste, analyses further hurdles for zero waste endeavors in the gastronomy industry and illustrates the constant balancing act of social businesses between staying true to one’s mission and catering to the needs, wants and expectations of the market.

This chapter describes the Knowledge Work Designer, a modelling method for knowledge work. It is based on two principles: (1) the separation of business logic and process logic and (2) the support of both structures and unstructured knowledge. Process logic can be represented in a structured way in BPMN and in a non-structured way with CMMN. For real processes there is no strict separation between structured processes and cases. Therefore the Knowledge Work Designer offers a deep integration of BPMN and CMMN. Business logic can be represented in a structured way using decision tables. Unstructured business logic can be represented in documents. The separation of business logic and process logic allows for simpler process model and easier maintenance.
