Counting Things, and RPEs

306 Million And Counting

On an unrelated email thread this morning I got to thinking about how I quantify the Flickr engineering team, and counting things in general.

Depending on how I’m counting I tend to place the Flickr engineering team at ~20 people. In that group I include everyone on our team who writes code (including HTML, CSS, Javascript, PHP, Java, Perl, Python, C, C++, XUL, or Objective-C). Additionally I include our operations team (aka sysadmins aka “service engineering”), our “tech support” team (technical customer care/qa/researchers), and various folks with “manager” in their title.

(a more traditional count would probably put the Flickr engineering team at 5 application/backend engineers, 4 front-end engineers, and 4 technical manager types.)

Which got me thinking about a new metric, the RPE or “roughly per engineer”. Mostly it’s a useful thought tool (for me) to think about what sorts of things scale up with economies of scale, and what doesn’t. Here are a couple of quick RPE metrics I pulled tonight.
