The 15 Irrefutable Laws of Computers

1. Any computer program that runs well is obsolete.
2. A good computer program is always accompanied by extremely bad documentation.
3. The value of a computer program is inversely related to the weight of its output.
4. Program complexities always grow to exceed the capabilities of the programer responsible for it.
5. Any time a system appears to be working well, something has been overlooked.
6. What you don't do is always more important than what you do.
7. In any computer program, constants should always be treated as variables.
8. Investments in system-reliability products always exceed the probable cost of errors they are designed to avoid.
9. The problem is not that computer salespeople are not knowledgable, it's that most of what they know isn't true.
10. If a system requires n number of spare parts, that will always be at most n-1 parts in stock.
11. Major software revisions are always requested after system installation is completed.
12. Installation and operating instructions are always discarded with the shipping cartons.
13. Any component part requiring the most frequent service or adjustment will be the least accessible.
14. Undetectable errors are infinite while detectable errors, by definition, are finite.
15. Nothing is impossible for the person who doesn't have to do the work.
