The more complex a human action is, the greater the need to formulate a plan of action, devise a method of implementation, and evaluate its execution. Such preparation is called design or planning, and can be defined as a conceptual preparation for action. Design and planning by themselves are so complex and important that they need informed preparation, which calls for systematic designological studies.

This volume brings together original contributions of researchers and practitioners in design theory, design research, and design studies. Its main purpose is to highlight the possibilities of the discipline of designology. Doing and thinking, or thinking and doing, whatever the order, are intertwined. That is why praxiology, the science of action, defines design as a conceptual preparation of action.

Included here are contributions from Jack Brzezinski, Eduardo Corte-Real, Nigel Cross, Michel Faucheux, Joelle Forest, Wojciech W. Gasparski, Ioannes B. Kapelouzos, Thorbjoern Mann, Tom Maver, Tarkko Oksala, Tufan Orel, Sevil Saryldz, and Ladislav Tondl. Designology is the latest volume in Transaction's highly regarded Praxiology series.
