A product road map is also a useful tool during the discovery phase. This helps stakeholders and product managers stay on the same page. It also gives them some framework for anticipating the development of products.
During the product discovery process phase, a company may have to do a lot of back-and-forth in order to identify which concepts are worth pursuing. This can be done by organizing data according to corporate processes and by ranking validated concepts by importance. It is also important to avoid a false turn. A good product team will never run short on product ideas.
Developing a product based on assumptions may be costly and risky. A well-organized discovery process can help avoid this costly and risky outcome. It also helps to make sure that you are not wasting time and money developing features that don't add value to the product.
