A lot of what I am working on is changing the mindset of a community of developers. Moving them from one tool to another, or to picking up a new tool.

What are some of the suggested or recommended ways to get a community to pick up a new meme?

While we can mandate tool usage, this is a last resort. I would rather have the developers move to any new tools of their own accord.

I'm not a programmer, I need to understand why a programmer will move from one tool to another.

Edited the title thanks to a fabulous comment! My world runs on Meme's, tipping points, and general pressures. This is why I needed to ask.

And clarifying yet more- I am the middle manager needing to plan and manage an implementation and not a sales person.
