Maintenance After a new system has been introduced, it enters the maintenance phase. The system is in production and is being used by the organization. While the system is no longer actively being developed, changes need to be made when bugs are found or new features are requested. During the maintenance phase, IT management must ensure that the system continues to stay aligned with business priorities and continues to run well. Summary Software development is about so much more than programming. It is fundamentally about solving business problems. 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 low-level machine-specific languages to higher-level 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 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 end- user 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.
