Chapter 10: Information Systems Development
Software development is about so much more than programming. Developing new software
applications requires several steps, from the formal SDLC process to more informal processes such as
agile programming or lean methodologies. Programming languages have evolved from very lowlevel
machine specific languages to higherlevel languages that allow a programmer to write software for a
wide variety of machines. Most programmers work with software development tools that provide them
with integrated components to make the software development process more efficient. For some
organizations, building their own software applications does not make the most sense; instead, they
choose to purchase software built by a third party to save development costs and speed
implementation. In enduser computing, software development happens outside the information
technology department. When implementing new software applications, there are several different types
of implementation methodologies that must be considered.
