Deploying updates can be a complicated process for large organizations with nodes numbering in the tens of thousands. A good deal of testing is required before deployment to the production network can begin.

So Update Tuesday often creates the need for a "Patch Wednesday Meeting" in order to discuss the testing schedule.

Microsoft now has some handy visual aids to assist.

Their October Bulletin MSRC post includes a graphical Severity and Exploitability Index.



Even better for IT managers is this Deployment Priority chart.



Very handy for those with limited resources that need to determine which patches to test first. Cheers to Microsoft.
