"Drew" Hamilton, Jr., Ph.D who was the last directory of the Ada Joint Program Office put it the way it was since he was apart of it. https://listserv.dtic.mil/listcgi/wa?A2=ind0608&L=it-cop-l&P=2765 Everybody does "overall life cycle cost analyses". In the case of the US government all departments it is every four to six years, for the long term analysis but it is every year for the short term aka the fiscal budget. Every company want to buy the equipment once and unless something happens to they would like to keep it forever. But in the real world, that is not so. The office computer hardware is obsolete in 18 months to 2 years. The life of the software depends upon the application. Microsoft, as a shelf life of 2 to 3 years and at it end it can cause a complete re-purchasing of all software. Other OSes have different time table than Microsoft. An accounting system last until the company's accounting changes, such as expansion into other business areas or merges with others. Or the accounting system can become obsolete at the next operating system release. Another example is an analyzer system for cars, once these cars are no longer in the general area, then this system become obsolete. That might be 5, 10, or even longer. Or it could be immediate, if no one drives this car in the shops area. In a true simplistic example, every time one goes to the market they does a cost analyses. In food, its brand, packing, and flavor. Now in electronic it might be features version price. And in all case its shelf and usage life. Like today, buying a VCR when DVDs are replacing VCR. But if price is a factor or easy of find equipment to play the program on, you might choose VCR. Because how many grandparents have DVD players. Of course, this is changing all the time, because what next after HD-DVD. You can make book on it, there is something and it will make all forms of DVD obsolete. "overall life cycle cost analyses" is a continual thing that is always being update by many factors. One factor change it might trigger an action based on the current "cost analyses" or for others it might take two or three factor changing to trigger such action. As for Ada and the E. Paige (retired in 88) memo, well to many friends listen to their ex boss. They gave his opion more weight in a government decission than he should of had.
