+## Vision for CI
+
+This is Lars's personal opinion, for now, but it's based on
+discussions with various people while at WMF. It's not expected to be
+new, radical, or controversial, compared to status quo.

+In the future, CI at WMF serves WMF, its developers, and the Wikipedia
+movement by making software development more productive, more
+confident, and faster. The cycle time of changes (the time from idea
+to running in production) is short: for a trivial change, as little as
+five minutes. At the same time, the safety and security of production
+is protected: malicious changes do not get deployed, mistakes are
+rare, and can easily be fixed or the problematic change reverted.

+Production here means all the software needed to run all the sites
+(Wikipedias in different languages, Commons, etc), as well as
