Instruments and checklists were developed to structure the processes and decisions of companies for successful corporate development. In this period the main contributors to design management were Michael Farr, Horst Rittel, HfG Ulm, Christopher Alexander, James Pilditch, the London Business School, Peter Gorb, the Design Management Institute, and the Royal Society of Arts. Debates in design disciplines were focusing on design science, design methodology, wicked problems, Ulm methodology, the relationship of design and business, new German design, and semiotic and scenario technique.
