Viability assumptions: Should we build it? There are many ideas that will work for our customers but won’t work for our business. If we want to continue to serve customers over time, we need to make sure that our solutions are viable—that they create a return for our business. This typically means that the idea will generate more revenue than it will cost to build, service, and maintain. However, some ideas are designed to be loss leaders and instead contribute to another business goal besides revenue.
