Have a plan for how it will integrate with your existing ecosystem such as tools, version control, continuous integration, data sources, etc if your org requires these things. I once worked as a principal at a .NET shop and had a smart engineer come to me wanting to use nodejs for part of a project and had to gently turn him down. I love to see enthusiasm for using new tools and personally like node/javascript, but his plan to use node didn't address important process concerns like hooking into our existing deployment, CI, and unit tests. Those concerns could have been addressed, but would have required significantly more effort than the actual project itself. Every org is different, but for us adding something without proper automation/tooling was a sin.
