Information Systems Development
This chapter focuses on the concepts surrounding the development of information systems. It begins with a discussion of software development methodologies, then covers programming languages and tools, and finishes with a review of implementation methodologies. As you read, reflect upon all the different pieces that must come together in order for a system to be developed.
Agile Methodologies
Agile methodologies are a group of methodologies that utilize incremental changes with a focus on quality and attention to detail. Each increment is released in a specified period of time (called a time box), creating a regular release schedule with very specific objectives. While considered a separate methodology from RAD, the two methodologies share some of the same principles such as iterative development, user interaction, and flexibility to change. The agile methodologies are based on the "Agile Manifesto," first released in 2001.
