The concept of Minimum Functional Product (MFP) is introduced as a way to break down large user stories into smaller, testable pieces that still provide value to the customer. By identifying MFPs, teams can prioritize how to build and test their product, keeping stories small and manageable. This approach helps drive conversations around what is critical for delivery, forcing teams to think in smaller pieces and improve estimation, planning, design testing, building, and delivering processes. The MFP concept is particularly useful in Continuous Delivery environments, where large user stories can lead to scope creep and waterfall life cycles. By establishing MFPs, teams can establish clear boundaries around what is in scope and what needs to be deferred, ultimately improving the value delivered to clients.
