Web development is a broad term for the work involved in developing a web site for the Internet  or an intranet (a private network). Web development can range from developing the simplest static single page of plain text to the most complex web-based internet applications, electronic businesses, and social network services. A more comprehensive list of tasks to which web development commonly refers, may include web design, web content development,  client-side/server-side scripting, web server and network security configuration, and e-commerce development. Among web professionals, “web development” usually refers to the main non-design aspects of building web sites,writing markup and coding. Most recently Web development has come to mean the creation of content management systems or CMS. A principle benefit of a CMS is that it allows non-technical people to make changes to their Web site without having technical knowledge.

For larger organizations and businesses, web development teams can consist of hundreds of people (web developers) and follow standard methods like Agile methodologies while developing websites. Smaller organizations may only require a single permanent or contracting developer, or secondary assignment to related job positions such as a graphic designeand/or information systems technician. Web development may be a collaborative effort between departments rather than the domain of a designated department.
