Developing an IS can be costly and a complex process to manage a group of professionals to deliver a new system on time and budget. There are several development models from the formal SDLC process to more informal processes such as agile programming or lean methodologies to provide a framework to manage all the phases from start to finish.
Software development is about so much more than programming. 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 applications does not make the most sense; instead, they choose to purchase or rent 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, organizations need to consider several different types of implementation methodologies.
An organization’s responsibilities to complete a software development do not end with the deployment of the software. It now includes a clear and systemic process to maintain and protect customers’ and projects’ data to address security and privacy concerns.
