61.大多數(shù)設(shè)備如何工作取決于它被生產(chǎn)成什么樣子，而不是設(shè)計(jì)成什么樣子。問題出在設(shè)計(jì)制圖上，錯誤理解了設(shè)計(jì)者的意圖或者元器件的特性。
Rule #62: Not using modern techniques, like computer systems, is a great mistake, but forgetting that the computer simulates thinking is a still greater mistake.
62. 不使用諸如計(jì)算機(jī)系統(tǒng)之類的現(xiàn)代技術(shù)是一個重大錯誤，但忘記計(jì)算機(jī)只是思維的模仿是一個更大的錯誤。
Computers and Software
Rule #63: Software has now taken on all the parameters of hardware (i.e., requirement creep, high percentage of flight mission cost, need for quality control, need for validation procedures, etc.). It has the added feature that it is hard as blazes to determine it is not flawed. Get the basic system working first and then add the bells and whistles. Never throw away a version that works even if you have all the confidence in the world that the newer version works. It is necessary to have contingency plans for software.
63. 軟件已經(jīng)承擔(dān)了一切硬件的參數(shù) (例如，需求延伸，高比例飛行成本，質(zhì)量控制需求，過程確認(rèn)要求等) 。還有個特點(diǎn)是，誰也不敢確定新功能不存在錯誤。首先讓基本系統(tǒng)工作，然后再加上鈴鐺和哨音。永遠(yuǎn)不要淘汰還能用的版本，就算你有十足的把握更新的版本已能勝任工作。有必要對軟件準(zhǔn)備應(yīng)急方案。
Rule #64: Knowledge is often revised by simulations or testing, but computer models have hidden flaws not the least of which is poor input data.
64. 認(rèn)識總是被仿真和測試所修改，但計(jì)算機(jī)模型并不會僅僅因?yàn)閿?shù)據(jù)輸入錯誤而隱蓋某些缺陷。
