Scrum is different to the waterfall model in that it prescribes the notion of iteration. With Scrum, a project is divided into a number of iterations, called sprints, each lasting between two to four weeks, with the goal of producing a fully tested and potentially shippable product at the end.

At the beginning of each sprint, the product owner and the team come together in what is called a sprint-planning meeting. In this meeting, the scope of the next sprint is decided. This usually includes top priority items from the backlog, which contains all incomplete work.

During each sprint, the team meets on a daily basis to review progress and flag any potential problems or impediments, and plans how to address them. These meetings are short, and the goal here is to make sure that everyone on the team is on the same page.

At the end of the sprint, the team will come together to review the outcome of the sprint and look at the things they did right and the things that did not go well. The goal is to identify areas of improvement, which will feed into future sprints. This process continues until the project is completed.
