Understanding how to measure success is extremely important to run a successful business, especially with medical device development. Return on Investment and Net Present Value are tangible measurements to evaluate whether a project is worth pursuing. They quantify risk and reward, showing whether a device is worth the investment today. 

However, financial models are only a part of the story since a medical device might not have an immediate ROI, but the long-term ROI could be enormous. An example of this would be robotic surgeries, as many physicians and patients were wary of them early on, but eventually they all adapted, and surgery has become so much better. Thus, financial models are not the only decision-maker, and several risks are involved in ensuring innovation brings profit as well as better outcomes to the population. 

How do you think companies should balance short-term financial goals with long-term investments and extremely innovative technologies? How do you think financial models can evolve for medical device development? What other factors should be looked at when making a decision to release a product?
