Below is an excerpt from Pat O'Brien's article talking about Keys to a Solid Putting Routine. Very good reading.

In the July issue, I wrote about how to use the design of the putter effectively to free up your stroke (see here) . It requires a neutral, balanced setup, where fundamentals matter.
In the coming months, I will discuss grip, alignment and ball position of a proper setup. While not imperative to have perfect fundamentals, they allow you to return the putter to square more easily.
When you are able to return to the putter to square without thought, you can fully take advantage of a solid pre-putt routine. The routine is highly individual. I would merely like to make some suggestions as to what it is should include.
Back in 2004 at The Byron Nelson, Zach Johnson and I developed the routine he still uses today. It is very gratifying to see it work under the most intense pressure situations. I am just as proud of helping him create this as I am helping him develop a stroke that repeats time and again.
