THE USER ERA 126<br />
The first phenomenon can be called limits to the design activity. The<br />
software factories of the late 1960s and early 1970s were established to solve<br />
most if not all software development problems. They have not, however,<br />
succeeded as envisioned. As systems developed and proliferated more users<br />
were tra<strong>in</strong>ed. Over time these users requested more and more changes to the<br />
basic systems. Such changes, part of the software “ma<strong>in</strong>tenance” process, have<br />
used up 70 percent of the <strong>in</strong>-house programm<strong>in</strong>g resources of most<br />
organizations. Unfortunately, this does not mean that 30 percent of the<br />
corporate programm<strong>in</strong>g staff will always be available for new functions. A<br />
hypothetical example shows why: If an organization began development of a<br />
system with 1,000 programmer/analysts, at the end of the effort 700 would<br />
rema<strong>in</strong> for ma<strong>in</strong>tenance and 300 would be available to develop a second<br />
system. This second design activity, when f<strong>in</strong>ished would require 210 personnel<br />
(70 percent) for ma<strong>in</strong>tenance, leav<strong>in</strong>g only 90 programmer/analysts for the third<br />
system. It is obvious from this example that the number of systems any s<strong>in</strong>gle<br />
organization can both develop and ma<strong>in</strong>ta<strong>in</strong> is f<strong>in</strong>ite. And user frustration is the<br />
ultimate result.<br />
The second phenomenon is <strong>in</strong>creased user literacy. For more than 20 years<br />
computers represented a mysterious technology, understood only by data<br />
process<strong>in</strong>g professionals. Today, however, computers are everywhere, and<br />
computer literacy, aided by software products that permit unique system<br />
development without the need to understand COBOL, FORTRAN, or any other<br />
high order language, has greatly <strong>in</strong>creased.<br />
The third phenomenon that has spurred movement out of the control stage<br />
is the technology explosion. The cost performance curve <strong>in</strong> logical devices has<br />
led to a sizable expansion <strong>in</strong> their use. If we cont<strong>in</strong>ue to acquire computers <strong>in</strong><br />
the future at the same rate as we have <strong>in</strong> the past, we will compound deliveries<br />
at 25 percent annually. Theoretically, computer growth requires an equivalent<br />
expansion <strong>in</strong> tra<strong>in</strong>ed programmers. Today there are 300,000 programmers. By<br />
one estimate, approximately 3 million would be needed by 1994 to ma<strong>in</strong>ta<strong>in</strong> the<br />
current computer-to-programmer ratio. S<strong>in</strong>ce such expansion is unlikely, greater<br />
dependence must by placed on the user community. Fortunately, the software<br />
<strong>in</strong>dustry has the capability to help solve the problem.<br />
The dynamics of change <strong>in</strong> the <strong>in</strong>formation <strong>in</strong>dustry and society's<br />
cont<strong>in</strong>u<strong>in</strong>g thirst for technology-aided solutions demand responses from<br />
organizational management. One user of computer<br />
