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.

Ultimately, the impresario must know when to simply get out of the way.

You would not let your kids do whatever they want. So the challenge is to create accountability in a non-mechanistic way. You cannot come in with a clipboard and check off boxes and figure out why something has not been done on schedule.

The imagination is like a muscle: it strengthens through use.

There's real "right brain" creativity that goes into all of the organizational processes that a company utilizes and must continually reinvent in order to conduct its business. But there are also the "left brain" accounting functions that must continually ask how the company is doing financially and whether the creative processes are working for the bottom line.

The impresario functions as a bridge and a translator. He or she is a bridge between the creative point of view - which is often very focused on the creative task itself - and the resource-allocation process. The impresario has to make certain the funds and people required to get that task completed are available.

In the end it is the musician who actually plays the notes. The impresario - or the project leader - is only there to make sure that happens. That is a very different type of management mind-set.
