Nearly a year and a half ago I wrote this post about why many large organizations are still using Internet Explorer 6. Every now and again, the post is re-discovered and is re-circulated and I get some great feedback about it. I’ve decided that it is time for a bit of an update on the subject, so here goes.
I’m going to assume that you’ve read my original post, but in one line, the reason many large organizations still use Internet Explorer 6 is application compatibility. My employer (a large government department) has recently experienced this first-hand, having had to postpone deployment of Internet Explorer 8 after discovering compatibility issues (mid-deployment) with some important business applications. I have no idea how come they only discovered the issues after starting to deploy. Either someone didn’t do due diligence and test before-hand, or worse, they were completely clueless about the risks of incompatibilities. Either way, as a fellow IT employee in the same organization, it’s down right embarrassing.
One of the most frequent comments I receive as feedback on my original post is that folks get the compatibility issues, but they believe that we wouldn’t be in this situation if these incompatible applications had been written using web standards. It’s the fault of the application developers that their applications only work properly with Internet Explorer 6.
