Scrum (software development)
open-in-new
<p>Scrum is an <a href="/facts/Agile_management/GCp8cbmW">agile</a> team collaboration framework commonly used in <a href="/facts/Software_development/UUfsAaYY">software development</a> and other industries. </p><p>Scrum prescribes for teams to break work into <a href="/facts/Goal/N5UtLKVk">goals</a> to be completed within <a href="/facts/Timeboxing/hon8Q7DB">time-boxed</a> iterations, called <i>sprints</i>. Each sprint is no longer than one month and commonly lasts two weeks. The scrum team assesses progress in time-boxed, <a href="/facts/Stand-up_meeting/daX2tD7h">stand-up meetings</a> of up to 15 minutes, called <i>daily scrums</i>. At the end of the sprint, the team holds two further meetings: one sprint review to demonstrate the work for <a href="/facts/Stakeholder_(corporate)/yN9L44ac">stakeholders</a> and solicit feedback, and one internal <a href="/facts/Retrospective/bvDdSlqy">sprint retrospective</a>. A person in charge of a scrum team is typically called a scrum master. </p><p>Scrum's approach to product development involves bringing <a href="/facts/Decision-making/NbJYprSw">decision-making</a> authority to an operational level. Unlike a sequential approach to product development, scrum is an <a href="/facts/Iterative_design/4GPzXnGT">iterative</a> and <a href="/facts/Iterative_and_incremental_development/wqT31VIC">incremental</a> framework for product development. Scrum allows for continuous feedback and flexibility, requiring teams to self-organize by encouraging physical <a href="/facts/Colocation_(business)/dqlMIWDF">co-location</a> or close online collaboration, and mandating frequent communication among all team members. The flexible approach of scrum is based in part on the notion of requirement volatility, that stakeholders will change their requirements as the project evolves. </p>
