Planning Poker is a popular method of efficient and effective work time estimation for software development teams. Widely used in Agile, the benefits of Planning Poker are not just about estimating completion time, but also include promoting all team members’ involvement. One of the benefits of Planning Poker is improved communication. Instead of listening to one or two people, everyone has the opportunity to voice their opinions and create an atmosphere of cooperation and creativity. The team can introduce new concepts and different points of view, which makes estimates more precise. Additionally, the benefits of Planning Poker include reduced estimation bias. When the estimates are made independently and openly, the differences in opinions become clear to the team who then has a chance to discuss them and reach a consensus. Also, the benefits of Planning Poker involve transparency. The team can follow more closely and assess project progression more accurately when everyone clearly knows their tasks and what they are betting on. Finally, the benefits of Planning Poker are not limited to enhanced estimation efficiency but also include better relationships between team members. As a result, work environment becomes fun and more dynamic.
