Using a product vision board is not a one-time activity, but a continuous practice that evolves with your product development. You can use your product vision board to guide your product development in several ways. First, you can use it to define and prioritize your product roadmap and backlog. By using your product vision board, you can align your product roadmap and backlog with your customer value proposition and your product differentiation. You can also use it to decide what features to build, what to measure, and what to test. Second, you can use it to communicate and collaborate with your team, stakeholders, and customers. By using your product vision board, you can share your product vision and direction with your team, stakeholders, and customers, and get their feedback and input. You can also use it to resolve conflicts, negotiate trade-offs, and manage expectations. Third, you can use it to review and adapt your product development. By using your product vision board, you can evaluate your product performance and progress, and identify gaps, risks, or opportunities for improvement. You can also use it to revisit and revise your product vision, target group, needs, and product as needed.
