Developer (software)

A software developer is a person concerned with facets of the software development process, including the research, design, programming, and testing of computer software. Other job titles which are often used with similar meanings are programmer, software analyst, and software engineer. According to developer Eric Sink, the differences between system design, software development, and programming are more apparent. Already in the current market place there can be found a segregation between programmers and developers, being that one who implements is not the same as the one who designs the class structure or hierarchy. Even more so that developers become systems architects, those who design the multi-leveled architecture or component interactions of a large software system. (see also Debate over who is a software engineer)

In a large company, there may be employees whose sole responsibility consists of only one of the phases above. In smaller development environments, a few people or even a single individual might handle the complete process.

The word "software" was coined as a prank as early as 1953, but did not appear in print until the 1960's. Before this time, computers were programmed either by customers, or the few commercial computer vendors of the time, such as UNIVAC and IBM. The first company founded to provide software products and services was Computer Usage Company in 1955.

The software industry expanded in the early 1960s, almost immediately after computers were first sold in mass-produced quantities. Universities, government, and business customers created a demand for software. Many of these programs were written in-house by full-time staff programmers. Some were distributed freely between users of a particular machine for no charge. Others were done on a commercial basis, and other firms such as Computer Sciences Corporation (founded in 1959) started to grow. The computer/hardware makers started bundling operating systems, systems software and programming environments with their machines.
