When everything looks like a nail…
A fondness for a singular tool is the downfall of every project manager, marketer, software developer or carpenter you will ever meet.
There are individuals who are constantly seeking the new, shiny bullet with which to slay their project demons.
And then there are other individuals who cling desperately to the one tool they know works for project management.
One of the better techniques I know of for project management is to understand how different project management systems, software and methods work, even if they directly compete with each other.
Then you can make an informed choice when deciding on which technique to use for a particular situation.
But if all you have is a single tool, then everything you see looks like you can use that tool on it.
