I find it amusing that reliability goes up when the team hits 11 engineers, then again when it hits 51 engineers, but then dips when it hits 100 engineers. Need to finally read my copy of the Mythical Man Month.
- gregdoesit 5y agoThis one was both surprising to me, but having worked on an app with >100 engineers, also less so. The challenge is how with 100 engineers you typically still want to ship 50-100x as much as with 1 engineer. And all those small features that the 1-3 mobile eng-sized teams work start to have unwanted/unexpected impact on each other, bringing down collective app stability. Also, the >100 Engineer apps are typically used globally, with often millions of users. Many of the crashes will come on Android, on exotic hardware / old OSes, in my experience. It is fascinating, regardless.
