To match the growing complexity of problems, there is a growing body of information and specialist experience. This information is hard to handle; it is widespread, diffuse, unorgenized. [...] the various specialist who retail it are narrow and unfamiliar with the form-makers' peculiar problems. As a result [...] the average designer scans whatever information he happens on, consults a consultant now and then when faced by extra-special difficulties, and introduces this randomly selected information into forms otherwise dreamt up in the artists' studio of his mind. (Alexander, 1964, p 4)
