Bluffing in computer industry

Sometimes I attend on deal meetings there marketing people try to steal the project from another companies.
They equipped with best experts in NewTechnologyShit areas. I see these marketing people with their puppy experts say : "We can do it even faster that required "
"We have a lot of specialists that would write a best software for your company" etc.
I am really sure that a most of them didn't do a home work, even they don't know what they need exactly to develop........
It's look me like PREFLOP BLUFFING in poker - you don't know what cards have your opponent, you have just two cards (and I'm sure not a best hand at table) and you are going all in(what the matter with you).
I'm advicing to this manager just relax and 'call' . You can raise just if you have a really good hand or if you have a huge stack(I'm taking about big profitable companies).
So relax, buddy!!
