I do think you need to ask the right questions, and especially the ones that you know people will not want to answer.
There are normal questions that we always ask, and that's part of the due diligence. I think whenever we're in a time of crisis and we're awarding large contracts, especially sole-source contracts, we need to go with what we call “enhanced due diligence”. You need to ask those questions.
You see it more in a macroeconomic way: “Are you going to be able to do the contract, and why are you the only one able to do the contract?” Very often, if only one person can do the contract, you need to ask yourself why there are not more competitors. Is it because no one wanted to actually do the contract? Is there something that we don't understand in the specifications we asked for, and no one wants to go for it because it's not going to be possible?
You need to ask questions and ask the person, “What's in it for you?” I know it's pretty stupid, but in business very often we say that. Ask a single question: “What's in it for you? Why are you the only one who is actually proposing for this project?”
