> If I were to estimate, this probably doubled efficacy of our junior devs while halving the (direct) productivity of senior folks. In my cases, it was immediately apparent that we came out ahead: the former outnumbered the latter by several times.
I really like this. I consider myself an intermediate developer, and can't even count the times a 5-10 minute conversation would have saved me an entire day - or week! - of wasted effort. I think this is easily overlooked because its not totally obvious that interrupting a highly productive, highly skilled developer could result in higher team productivity.
