Guide: Iterative Development in Scrum

What is Iterative Development in Scrum?
Iterative development in Scrum is a process methodology where a large development task is broken down into smaller parts (iterations). These iterations are then incrementally completed in separate cycles. Each of these components is developed, tested, integrated and made ready for delivery by the end of each iteration.

Why is it Important?
Iterative Development is vital in Scrum due to several reasons. It allows teams to manage complex projects more efficiently, resulting in early detection and rectification of defects. Through iterative development, user feedback can be incorporated quickly, which significantly enhances the end product. It also helps in risk mitigation as it allows for changes at a later stage in the project.

How does it work?
Scrum follows an iterative, incremental approach to project management, enabling teams to focus on a manageable scope of work in each iteration. An iteration, often known as a sprint, lasts typically between one to four weeks. Within these sprints, teams design, develop, test, and deliver a potentially shippable product increment.

Exam Tips: Answering Questions on Iterative Development in Scrum
- Understand the concept thoroughly: Before writing the answer, ensure you know what iterative development involves, its benefits, and how it fits into the Scrum framework.
- Use real-life examples: Explaners become clearer with relatable examples.
- Show the comparative advantages: Discuss how iterative development results in quicker feedback and flexibility.
- Remember it's a cycle: Do not forget to depict iterative development as being a cycle of continuous improvement.
- Incorporate Scrum terminology: Terms like 'sprint', 'product increment' etc., should be used while answering.
- Know the roles: Understanding various roles involved in the process will be a plus.
