Computers will not be perfected until they can compute how much more than the estimate the job will cost. | |
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" | |

The Briggs-Chase Law of Program Development: To determine how long it will take to write and debug a program, take your best estimate, multiply that by two, add one, and convert to the next higher units. | |
It's grad exam time... MEDICINE You have been provided with a razor blade, a piece of gauze, and a bottle of Scotch. Remove your appendix. Do not suture until your work has been inspected. (You have 15 minutes.) HISTORY Describe the history of the papacy from its origins to the present day, concentrating especially, but not exclusively, on its social, political, economic, religious and philisophical impact upon Europe, Asia, America, and Africa. Be brief, concise, and specific. BIOLOGY Create life. Estimate the differences in subsequent human culture if this form of life had been created 500 million years ago or earlier, with special attention to its probable effect on the English parliamentary system. | |
A [golf] ball hitting a tree shall be deemed not to have hit the tree. Hitting a tree is simply bad luck and has no place in a scientific game. The player should estimate the distance the ball would have traveled if it had not hit the tree and play the ball from there, preferably atop a nice firm tuft of grass. -- Donald A. Metz | |
The Vet Who Surprised A Cow In the course of his duties in August 1977, a Dutch veterinary surgeon was required to treat an ailing cow. To investigate its internal gases he inserted a tube into that end of the animal not capable of facial expression and struck a match. The jet of flame set fire first to some bales of hay and then to the whole farm causing damage estimate at L45,000. The vet was later fined L140 for starting a fire in a manner surprising to the magistrates. The cow escaped with shock. -- Stephen Pile, "The Book of Heroic Failures" |
