What are the characteristics of information systems (IS) in large-scale systems development projects?

What will be an ideal response?

Information systems (IS) in large-scale systems development project have many features and functions. They require substantial computer resources and necessitate the creation of multifaceted, complicated computer programs. They process databases with hundreds of tables; dozens, possibly hundreds, of relationships; and terabytes of data. Such large-scale systems affect many business processes and support hundreds, possibly thousands, of concurrent users.
Because of their size, such systems require a large development team, often composed of 50 to 100 or more business and systems analysts, programmers, PQA engineers, and managers. To add further complexity, large-scale systems are often simultaneously developed at multiple sites. A project might involve teams in the United States, India, China, and other countries. Additionally, the development of large-scale systems can involve integrating products and services from different companies. In these larger development projects, some companies provide licensed software; others provide particular expertise, such as database design; and others provide development labor. Large-scale systems are frequently localized for different languages. Finally, large-scale systems development requires extended development intervals, sometimes as long as five or six years.
