Start with the problem
Describe who is experiencing the problem, what they are trying to do, and why the current experience falls short. A clear problem statement makes later product decisions easier.
Choose the first journey
Pick one meaningful end-to-end journey and identify the smallest set of capabilities needed to support it. Separate essential work from ideas that can wait.
Learn before expanding
Put the first experience in front of representative users. Gather feedback, review what worked, and use those findings to decide what to improve next.
