This publication was developed as a learning resource for the C3 Design Methodology course, which forms part of the curriculum of the Amsterdam Academy of Architecture. This reader is a product of our series on Design Methodology and it presents six essays on design processes written by Dutch professionals, with a particular focus on their personal design process. We are giving the floor to a number of our respected teachers and professionals in this reader and hope that this can also ignite a discussion within other design schools. With contributions by Jo Barnett, Tom Frantzen, Jan-Richard Kikkert, Frits Palmboom, Paul Roncken and Jan Peter Wingender
