REVALIDATION THE WATERFALL METHOD


Royce didn't actually name the waterfall methodology—he used the illustration to describe how software was developed in the early era. It first seems to have earned the moniker a few years later.


Te Army isn’t likely to find another magical rabbit in a hat that will make all its software acquisition woes dissolve. Instead, the solution will come—as it did then—when smart people look to recreate tools and processes that make the avail- able talent sufficient to the task. Colorless money—funding not lashed to research, development, test and evaluation, for example—has its proponents, and may be part of the solution, but only a part. Whatever the ultimate solution, it seems inevitable that it will pose new challenges.

Back then, the issue that the Army faced wasn’t a personnel problem. Indeed, the Army showed that it was a technologi- cal problem, and then solved it with an entirely new solution. Today’s “staffing challenges” also may not, in the end, have a personnel solution. Whether the solution will be technological, only time will tell.


Solutions to challenges tend to create other, unforeseen challenges. Back in the 1940s, no one could have foreseen the lack of sufficient talent for the Army’s software needs because most people weren’t clear on what software was. Today, that model has flipped. Software is central and computers are commodities.


government and contractor staff.” Compe- tition for talent is so intense that it’s been called a war. In 1945, the Army replaced hundreds of people doing the math for firing tables with a revolutionary, first-of- its-kind machine that spawned an entirely new industry.


The magic and the money live in the software.
