Everyone might agree with the fact that Scrum is the most popular methodology in Agile development. Many organizations use Scrum due to its simplicity and flexibility. In Scrum, work is confined to a regular, iterative work cycle, known as a sprint. Most of the time one sprint lasts from one week to 4 weeks, but in some exceptional cases sprint might take up to two months. Each scrum team can face such challenge – decide upon sprint length.
