The team divides the job of reaching the final product into various sub-jobs as sprints, and at a time, a sprint is completed regardless of the final product.
Team work:
No single individual is working alone. The people work as a team to reach a goal by completing their tasks as discussed in daily scrum.
There is a constant delivery of some results for review and analysis instead of waiting for the entire development cycle to get completed to get a final product.
Reviews and Adaption:
Since we get small results or sub-products with the completion of the sprint, we can get reviews over them and adapt the iterations.
