It will let the camera apply a fine-tuning adjustment to make sure you get accurate focus out of the AF system.
Read your camera manual for exact details on how to do this, but you should find the relevant settings somewhere in one of the AF menus (that's where they are on a 5D3, and I assume the 6D is similar).
The basic idea is that you set the camera up on a tripod and take pictures of a test chart. Make focus adjustments until you are getting accurate AF results. You can buy a test chart like this (http://www.amazon.com/Datacolor-SLC100-SpyderLensCal/dp/B0041L3JS4/ref=sr_1_1?ie=UTF8&qid=1425332338&sr=8-1&keywords=focus+test+chart), which has a nice angled scale so you can easily read off whether focus is off to the front or back. But you can also just take a picture of any target that has plenty of detail, it's just a bit more laborious to get it right.
Edit: for zoom lenses, you'll want to do the separately for the wide and the long ends of the range. The adjustment can vary across the range. Your camera should be able to store a separate adjustment for each end.
I'd suggest grabbing one of these to see if the lens is missing focus.

Very much so. When you set focus on the target, it was very easy to see front and back focusing with various lenses.
If you are shooting wide aperture, you need to have focus nailed. That is why this adjustment exists on pro bodies for each lens. You can set adjustment for near and far focus. With Sigma zooms, you can set near and far focus for one of 4 focal ranges, using their dock.
This is why it is common for DLSR shooters that are photographing a focus critical shot to use live view (i.e. make their camera a mirrorless and focus on the sensor.) Until dual pixel AF of Canon, this really sucked. Like first generation mirrorless AF.
Make sure you aren't using any filters at large apertures. I found that this makes a huge difference and can really mess the focus up. Also, get your lens calibrated or do it yourself with one of these
I've got one and it works great.
