"Bandwidth" really means time or people. "Get down in the weeds" is the goofy way of asking to focus on details, and "Preso", well, it's just cringe-inducing. Web directory Unsuck It pulls off such management-to-actual-human translations with clarity and sometimes hilarity.
Search or browse Unsuck It's offerings, and you'll find some common stuff, some items you can't believe need to exist ("bucketize" is just categorise), and the occasional "Accelerated Emergence of High-Maturity Behaviours" that will make you want to thrust your forehead through your keyboard. If you find an item that you're exposed to far, far too often, you can share your pain on Twitter or even email it directly to the offender, though it's coming through your own address.
