"In a large pharmaceutical company, where it's a big bet, you're going to need finance people to be involved in the decision-making because the investment can run into the hundreds of millions of dollars. You're going to have to run scenarios. You might even need agreement from the C.E.O. to make that type of decision. If it's an incremental, low-cost decision in a marketing-oriented company, it may be a very different set of stakeholders a lot further down in the organization."
