The best way to enable the effectiveness of an agile project for the rapid development of a new software application is to separate the work into sprints. Sprints are short, time-boxed iterations that deliver a potentially releasable product increment at the end of each sprint. Sprints allow agile teams to work in a flexible and adaptive manner, respond quickly to changing customer needs and feedback, and deliver value faster and more frequently. Sprints also help teams to plan, execute, review, and improve their work in a collaborative and transparent way. Project segments, phases, and milestones are not specific to agile projects and do not necessarily enable the effectiveness of an agile project. References: Agile Project Management [Whatis it and How to Start] - Atlassian, CISA Review Manual (Digital Version).
