ABSTRACT
INTRODUCTION All built environment, as well as all the artifacts we are daily using in the framework of it, exists because it has been produced. It is the ability to produce that distinguishes between the rich and the poor nation. It is the ability to produce in a sustainable way that seems to determine the fate of mankind. Without debate, production is of central significance for human societies. However, this invites the question: What do we know about production? What determines the outcome of production? Why are some factories, nations and industries more productive than others? Given that sciences tend to present their most fundamental knowledge in the form of theories: What is our theory of production?
