What processes and performance benchmarks do top US software companies follow to ensure quality software?

How do I check whether a US software development company can handle a company my size?
Primarily, look for case studies that name the client and the person who signed off. Vague, anonymized case studies hide the exact details you need to judge whether a vendor has handled a business like yours.
A good example of this in practice is Designli, which publishes named stories, including work for a mid-market firm with around $100 million in annual revenue.
