In the sense you gather a bunch of people for a limited time project and then they disperse. Which is how many startups operate when their aim is to be bought out by a larger firm and make a shitload of money in the process.

Are all the people who work at such a place necessarily better at their jobs than those who do a similar job at a different place ? No. Could they have been replaced by Mr. Doe ? Yes.
BUT if they are at the right time at the right place and they are sufficiently good that can be enough. A programmer could be working for the next Google, but if he sucks he'll be out.

Similarly, you might say Harrison Ford didn't 'make' Star Wars, but if he was really terrible, either George would have kicked him out, or the movie might have tanked.
