The absolute worst thing that can happen is when some clueless manager gets a powerpoint sales pitch, then comes in and says "we're doing everything in now!"
Inevitably, the sales pitch is either grossly exaggerated or outright lies, the "solution" costs a fortune, it's not flexible, anytime you have to customize something (and you will if your business does anything worth doing) it costs a fortune and requires an army of consultants, and you're just going to annoy staff into submission with both inferior and more expensive tools.
I've dealt with this. They come in and promise it can do the moon. Then you ask said manager if it can do any specific thing that we're actually doing right now. They stammer and have no idea, but they're sure it must be able to, because the salesman said it could do anything. In a couple of years when they realize it actually can't without five times more effort than what you had before, said manager will of course never admit their mistake.
If you're going to be making those decisions, involve your staff. They know what you actually need, since they spend every day dealing with it.
Also - walls. Walls are good. Open plan offices are productivity destroying monstrosities. The biggest problem developers have is distractions, and open concept offices are designed entirely to create more distractions. If two people need to talk about something, the entire office doesn't want to know about it.
