Guess Office 2016 users have to wait until El Cap 10.11.1 is released if they still want to be productive. According to Macworld the update released earlier this week does not address crashes with Office apps on OS X 10.11. An update note from Microsoft stated:

On October 13, 2015, we released an update to Office 2016 for Mac containing great new features, security fixes, and stability improvements. This update doesn’t address the issues experienced by Office customers with OS X 10.11 El Capitan. We are actively working with Apple to ensure resolution with the next update of OS X 10.11 El Capitan.

So for now some of use are still waiting to see what El Capitan has to offer. The update mentioned in the note can be found here - MS15-110 Update for Office 2016 for Mac.
