There is a broader truth about software usage that follows something like the 80/20 principle: most users will only ever use about 20% of your application’s features, but each user uses a different 20%.
The writer uses Word for drafting but never touches mail merge. The analyst uses Excel for pivot tables but never for scripting. The PowerPoint user never animates a single object. They are all using a different slice of the same monolithic suite, and each thinks their slice is the most important part.
When Microsoft releases new updates to their Office suite, many people get annoyed that their application is now bloated or that their personal workflow is now broken. Why is the application slower? Why are there so many new features that no one cares about? Why does it consume so much memory?
It’s not just that users don’t use the other 80%, they may actively resent it for getting in the way of their 20%.
