Full Guide: Iterative Development

What is Iterative Development?
Iterative Development is a software development process which emphasizes the iterative, or repetitive, development of a system or software. In this approach, development is broken down into smaller, manageable sections (iterations) which are planned, developed, and tested in each cycle.

Why it is Important?
Iterative Development is vital because it allows for flexibility in the development process. Changes can be made more easily within each iteration as feedback can be incorporated throughout the development. This process also reduces risks as developers can identify and rectify issues early on.

How it Works?
Iterative Development works in recurring cycles where each iteration involves steps like planning, requirements analysis, designing, coding, and testing. After each iteration, a working product should be able to be presented.

Exam Tips: Answering Questions on Iterative Development
1. Understand the Iterative Development process thoroughly: Familiarize yourself with its steps, benefits, and why it is used.
2. Use real-life examples: When asked to explain or give an example, use practical, real-life cases of Iterative Development.
3. Explain the importance of feedback: The process of Iterative Development heavily relies on feedback after each iteration. Make sure to highlight this in your answers.
4. Practice diagrams: Diagrams are a great way to visualize and understand the process. Practice creating diagrams for this model.
5. Discuss the importance of testing: The ability to detect and correct errors early is a major advantage of Iterative Development. Be sure to mention this in your answers.
