I work on a very small team (4 engineers), so we have all commits for all branches posted to our engineering chatroom.<p>Everyone knows what everyone else is working on (and we all work in the same room), so when someone is on a task that we know my have some snags&#x2F;difficult-to-design solutions, we&#x27;ll all periodically take a break and look at decisions other people are making on their particular feature, providing feedback when appropriate.<p>Of course, since we all work in the same room, we can also use the WTF&#x2F;minute metric to see (well, hear) when one of us is deep in the weeds and could use a second pair of eyes to pull us out.<p>[EDIT: and I know this won&#x27;t scale too far beyond a team of our size, but for us it works quite well right now]
