If someone sent you here, it’s because you used “bottoms up” when you should have used “bottom up”.
Bottom up is used to refer to a process or method that comes from people at the base of a hierarchy—on the bottom—rather than top down, from the top of the hierarchy. In almost every corporate communication you will ever send, you want to say “bottom up” rather than “bottoms up”.
Bottoms up is what you shout to your buddies when you want them all to slam their beers. Hardly appropriate corporate behavior unless you work at an early stage startup that just raised a too-big series B.
The worst part of the bottom up growth of “bottoms up” is that it's created the expression “tops down”, which is a completely insane and nonsensical concept. There is one top! There can’t be multiple tops down!
Please, stop the scourge of “bottoms up” and its twisted twin “tops down”.
