Scrum is a framework for product management commonly used in software development, although it has been used in other fields including research, sales, marketing and advanced technologies. It is designed for teams of ten or fewer members who break their work into goals that can be completed within time-boxed iterations, called sprints. Each sprint is no longer than one month and most commonly lasts two weeks. The scrum team assesses progress in time-boxed daily meetings of up to 15 minutes, called daily scrums (a stand-up meeting). At the end of the sprint, the team holds two further meetings: one sprint review intended to demonstrate the work done for stakeholders and solicit feedback, and one sprint retrospective intended to enable the team to reflect and improve.
