• Any given program; when running; is obsolete.
• Any given program costs more and takes longer.
• If a program is useful; it will have to be changed.
• If a program is useless; it will have to be documented.
• Any given program will expand to fill all available memory.
• The value of a program is proportional the weight of its output.
• Program complexity grows until it exceeds the capability of the programmer who must maintain it.
