Agile teams move quickly, incrementally adding new capability sprint after sprint. The agile delivery team is dependent on requirement information to assure priorities/expectations are clearly understood upfront. When the project milestone planning (content, priority, purpose, and timing) side is not ready, the delivery team is left to make assumptions to fill in the gaps. This practice can lead to misaligned expectations and rework. Those on the business side need to align their milestone planning with the delivery team's sprints.
Atlas Requirement Date Planning enables Atlas users to define specific definition dates for features, and measure/track against those time-frames. By defining and tracking the project milestones, Atlas users can align their work with the delivery team, assuring business needs are available when requested by engineering.
