I have the feeling that many people tend to turn to a new software instead of trying to master the one available. I am not saying that existing software should not be discarded if it lacks features. But I feel there is a trend like "the grass is greener with new_gadget_name".
E.g.: there is an intranet. Someone finds out, that wikis are cool (and they are), so a wiki is introduced. Due to bad support or communication (or the will of someone higher up), the wiki never manages to completely replace the intranet, although it does grow daily. Now you have both worlds. Then one day you find out that another department has started using OneNote or Evernote for collaborative work, while there are less progressive people still keeping project notes in spreadsheets, textdocs and slides all over the fileserver.
I know that different people have different preferences for tools and there is no "one tool to rule them all". But for comprehensive documentation (and I do not just mean specifications and manuals), I believe there should be a fixed set valid for all.
Is this behavior an anti-pattern and does it have a name? - or am I just too square on this topic (please be kind in the comments)?
