Karcher also found it interesting that this time around, the momentum of open-source alternatives such as OpenOffice and LibreOffice has slowed down, compared with the last time Forrester conducted this survey about two years ago. "Their adoption hasn't significantly improved," he said.
Also helping Office is the fact that IT departments generally don't find the process of upgrading the suite to newer versions very challenging, and that most upgrades don't require hiring outside consultants, according to the survey.
The latest version of Office that's sold via perpetual licenses -- pay once and own it forever -- is called Office 2013, while those sold via subscriptions renewed annually carry the Office 365 brand.
The most popular Office version in use at work is Office 2010 (present in 85 percent of surveyed companies), followed by Office 2007 (51 percent) and Office 2003 (28 percent).
Office 2013 is in 22 percent of surveyed companies, but adoption is slower than it was at a comparable stage for Office 2010. Forrester found that 36 percent plan to adopt Office 2013. The main reason for moving to Office 2013 is that the upgrade is included in the companies' license program. Only a third of respondents cited "compelling features and benefits" as a reason for upgrading.
Office for Mac 2011 is in 17 percent of the surveyed companies, followed by Google Docs (13 percent), Microsoft Office Web Apps (9 percent), OpenOffice (3 percent), LibreOffice (2 percent) and Corel WordPerfect Office and IBM Docs, each with 1 percent.
So, in a nutshell, when it comes to office suites at work, the more things change, the more they stay the same.
