The amateur seldom has to test a program thoroughly. For the university student, too often the only requirement is to meet stated output criteria in order to pass a course. The fact that most of the control paths have never been exercised is not of much concern in either submitting or planning the program. Programmers: The Amateur vs. the Professional Testing Installation FIGURE l. The stages of the software lifecycle. 39 40 Henry Ledgard Only a few decades ago, almost all programming was done using the direct machine codes of the hardware.

This means that the software does not stand alone. In some cases, these concerns can be paramount. Things like protocol for input and output may dictate severe constraints on any supporting software. Often the programmer has no latitude in such matters, but must go to great detail to guarantee that the behavior of software is accurate. Beyond these more-or-Iess technical requirements, there is another issue that dramatically distinguishes the professional from the amateur. A professional does not work in isolation.

About the same time, to get into the computer business. The two divisions then went on to build and market the UNIVAC and 1101 computers, respectively, for Remington Rand. It was not until 1956 that the Sperry Corporation merged with Remington Rand to form the Sperry Rand Corporation. ) I remember the period well; I was in charge of Sperry's digital computer development at that time and designed Sperry's first digital computer, the SPEEDAC, beginning in 1950.
