The Agile Manifesto for Software Development doesn't says much about Agile outside Software Development. While it introduces principles and ideas that potentially have a broader applicability beyond IT.
The Agile Manifesto for Software Development doesn't says much also about Agile beyond the team level. While its principles and ideas about collaboration and simplicity can be applied also for the collaboration between teams.
The community and the wiki I'm thinking about should be for people to share Agile principles, practices, and patterns that works beyond IT or/and beyond the team level (e.g. in a non-Tech department and/or in a multi-teams setup).
I wonder if for casual contributors would be as easy to leave a comment as in a Google doc.
While I'm more confident that for interested contributors a fed wiki on this topic would create a space to garden and share new interesting ideas and conversations, and learning.
