Agile Estimation is a technique used in Agile project management to predict the effort required to complete tasks or features. It helps teams prioritize work and allocate resources effectively. Common methods include story points, which measure complexity, and ideal hours, which estimate time without interruptions. Teams often use planning poker or T-shirt sizing to reach a consensus on estimates. These collaborative approaches encourage discussion and ensure that all team members contribute their insights. Accurate estimation improves project planning and enhances the team's ability to deliver value to stakeholders.
