It is a very humbling experience to make a multimillion-dollar mistake, but it is also very memorable. I vividly recall the night we decided how to organize the actual writing of external specifications for OS/360. The manager of architecture, the manager of control program implementation, and I were threshing out the plan, schedule, and division of responsibilities. The architecture manager had 10 good men. He asserted that they could write the specifications and do it right. It would take ten months, three more than the schedule allowed. The control program manager had 150 men. He asserted that they could prepare the specifications, with the architecture team coordinating; it would be well-done and practical, and he could do it on schedule. Furthermore, if the architecture team did it, his 150 men would sit twiddling their thumbs for ten months. To this the architecture manager responded that if I gave the control program team the responsibility, the result would not in fact be on time, but would also be three months late, and of much lower quality. I did, and it was. He was right on both counts. Moreover, the lack of conceptual integrity made the system far more costly to build and change, and I would estimate that it added a year to debugging time. -- Frederick Brooks Jr., "The Mythical Man Month" | |
"Pseudocode can be used to some extent to aid the maintenance process. However, pseudocode that is highly detailed - approaching the level of detail of the code itself - is not of much use as maintenance documentation. Such detailed documentation has to be maintained almost as much as the code, thus doubling the maintenance burden. Furthermore, since such voluminous pseudocode is too distracting to be kept in the listing itself, it must be kept in a separate folder. The result: Since pseudocode - unlike real code - doesn't have to be maintained, no one will maintain it. It will soon become out of date and everyone will ignore it. (Once, I did an informal survey of 42 shops that used pseudocode. Of those 42, 0 [zero!], found that it had any value as maintenance documentation." --Meilir Page-Jones, "The Practical Guide to Structured Design", Yourdon Press (c) 1988 | |

The Hitchhiker's Guide to the Galaxy has a few things to say on the subject of towels. Most importantly, a towel has immense psychological value. For some reason, if a non-hitchhiker discovers that a hitchhiker has his towel with him, he will automatically assume that he is also in possession of a toothbrush, washcloth, flask, gnat spray, space suit, etc., etc. Furthermore, the non-hitchhiker will then happily lend the hitchhiker any of these or a dozen other items that he may have "lost". After all, any man who can hitch the length and breadth of the Galaxy, struggle against terrible odds, win through and still know where his towel is, is clearly a man to be reckoned with. -- Douglas Adams, "The Hitchhiker's Guide to the Galaxy" | |
