Can you succeed without good people?
The answer is a sound yes, but for a given value of success.
A bad team can still get a product out, and that product may even be successful. But the cost that this requires is far greater than it would have been otherwise, often to the point where you have no choice but to scrap the project. The really sad part is that some people accept this cost as the true cost of building software.
Oh, and good people doesn't necessarily equate to experts.
You need a few good people, but the rest of the team can follow fairly simple check list approach to development. There are a lot of stories about teams like that, and most of them end with a big project failure. Usually, this is because there was a hard separation between the people the business consider as the high end and the regular developers. This usually cause the people who actually dictate the architecture and shape of the system to become totally oblivious of any design issues that they may inflict on the rest of the team.
Having a mixed team, with the architecture and the implementation done by the same group, is a much better proposition in the long term. Note, however, that I am explicitly not saying that the whole team should take part in the design. This is an ideal circumstance, and I haven't found it to be either common or even desirable in many cases. Design by committee is rarely a good idea, and I much prefer either design by addition or design by feature / feature batch. Again, those depends on the type of team that I am working on.
Another thing to note is the difference between technological experts and business experts. In both cases, we are talking about developers, but in technological experts are good for one thing, clearing the way so the developers who actually understand the business can get things done, fast.
I will reference again my posts about JFHCI, as a good example of how I think those things should be done.
