Creativity is not like the weather: You can do something about it. And you can measure it well enough to determine its effect on sales and profits.

You need judgment, you need to utilize conventional resource-allocation analysis, you have to work backward from estimations of the market to the current investments and you have to do some benchmarking of your product and its potential against your competition.

Knowing how to set those standards - which are often more subjective than analytical - means knowing how to communicate the difference between something that is great and something that is just O.K.

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.
