HR is governed by laws and regulations much of the time. However, we also have some nifty formulas that help us do our jobs on a daily basis. Below you will find some interesting resources that should help you with any questions you have. Make sure you subscribe for free updates so that you never miss a hot news item or funny article.

A nicely done formula or equation is pleasant to look at.  The ability to take rows and rows of endless numbers and force them into a format that is easy on the eyes is to be respected.  Heck, even a chart can be interesting if you pick the right one (like this).

Know Your Limits

I have spent a good bit of time in the past week or two developing derivatives of calculus formulae that express HR concepts (geek alert).  My favorite so far involves limits.  The limit formula has boundless possibilities for application, and coming up with new concepts is a tricky, yet interesting, way to spend some time brainstorming.

It’s been quite a few years since I had a calculus class, so anyone that can say this better can feel free to chime in.  Limits basically say that as value x approaches a predetermined point, two dissimilar items become equal.  The example my calculus teacher always used was “As the engineer’s grade approaches zero, an engineering degree becomes a business degree.”  In simpler terms, the lower the engineer’s grade, the more likely he/she is to become a business major (obviously he was an engineering fan :-) ).  Another easy one would be “As your wallet approaches full, dinner becomes a steak.”

HR Applications

The one that’s been bouncing around my head is “As HR approaches awesome, organizations become amazing.”  It’s not quite ready for prime time yet, but at least it’s something. Have a favorite HR formula, ratio, or equation? Share it below!
