You are a project manager working for a technology company that develops smart Bluetooth-enabled wearables for dogs. The product currently under development features a harness that gently vibrates when the dog gets beyond a specified range from the owner’s smartphone. You are developing the application that controls the harness using an incremental approach and have decided to create a prototype to gain feedback from your top five customers. The prototype will contain only a subset of features. What benefit does the team hope to gain by using this approach?

A. Spread out costs throughout the life of the product B. Engage top customers to prioritize their requirements C. Increase the speed of delivery and gain feedback early D. Fail fast to reduce cost of development
