Words are easy to change, but don't accomplish much. - Gerald M. Weinberg

Systems are complex. A computer system is not just hardware, not just software, not even just people plus hardware plus software. The procedures, formal and informal, that have evolved with the system are part of the system; so is the current load on various components, and so is the attitude and experience of the users. Even among the commonly accepted “parts” of a system, clear lines of separation do not exist. Hardware merges with operating system, operating system merges with programming language, programming language merges with debugging tools, debugging tools merge with documentation, and documentation merges with training, and all of them mingle with the social climate in which the system is used.

Although technology often leads science in discovery, the philosophy of technology is usually drawn from the scientific philosophy of its time. In our time, the technology of machines has drawn its inspiration from mechanics, dealing with complexity by reducing the number of relevant parts. The technology of government, on the other hand, has drawn upon statistical mechanics, creating simplicity by dealing only with people in the structureless mass, as interchangeable units, and taking averages.

One of the hardest choices for technical stars who become leaders is losing touch with the latest in technology.
