Another example: either you succeed or explain

Another example which popped into my head. Let's say you have a strong reference. Maybe an advisor that supports your product, a customer that said he/she will buy your product once it's available. Maybe you want to state your own achievements in order to show that "you know best". When you tell someone about this reference, do you need to explain? 

If it was that successful and that strong, a name of a person/customer/product would be enough. They're successful, so there's no need to explain.

Something to think about when looking for references. And, it's also something to think about when developing your own career.
