According to the Professional Scrum Product Owner™ II certification guide1, the Product Owner is accountable for maximizing the value of the product resulting from the work of the Scrum Team. This means that the Product Owner should have a clear vision of the product, understand the needs and desires of the customers and stakeholders, and prioritize the Product Backlog items based on their value and urgency. The Product Owner should also use evidence-based management to measure the value delivered by the product and make informed decisions about the product strategy and direction.
In this question, Product A has a high current value, which means that it is generating a lot of revenue and satisfying the existing customers. However, it also has a low unrealized value, which means that it has little room for improvement or innovation, and may face competition or obsolescence in the future. Product B has a low current value, which means that it is not generating much revenue or satisfying many customers. However, it also has a high unrealized value, which means that it has a lot of potential for improvement or innovation, and may capture new markets or opportunities in the future.
Taking a long-term view, the Product Owner should weight the investment toward Product B, since it has more potential to deliver value in the future. This does not mean that the Product Owner should neglect Product A, but rather balance the investment between the two products based on the expected return on investment and the risk involved. Investing equally in both products may not be optimal, as it may result in underinvesting in Product B and overinvesting in Product A. Weighting the investment toward Product A may not be wise, as it may result in missing out on the opportunities offered by Product B and losing the competitive edge in the market.
