Good developers are a necessary ingredient of a much larger recipe.

People think that a good process means you can toss in crap developers, or that great developers mean that you can have a bad process.

In my experience, I worked for a 100-year-old Japanese engineering company that had a decades-long culture of Quality. People stayed at that company for their entire career, and most of them were top-shelf people. They had entire business units, dedicated to process improvement and QA.

It was a combination of good talent, good process, and good culture. If any one of them sucks, so does the product.
