The three main areas that should be focused on to assess feasibility of the solution are distribution channels, capabilities, and potential partners. Distribution channels are the ways or methods that a product or service reaches the customers, such as online, in-store, or direct. Capabilities are the skills, resources, or technologies that are required or available to implement a solution, such as platform features, integrations, or tools.
Potential partners are the external entities or organizations that can help or support the delivery or operation of a solution, such as suppliers, vendors, or consultants. These areas help evaluate the technical and operational feasibility of the solution, and identify the gaps or opportunities for improvement or innovation. References:
