“everyone helping each other finish what they’re doing”?

Wanna increase MTBF of your system?

Try building quality in by shifting left on the collaboration. Instead of mobbing on the outage, mob during the development. Diversity of thoughts, needed skills and system understanding builds the quality in.

Wondering why your efforts to reduce PR size further are not going to work?

With every halving of the PR size, you get 2x more interruptions for each of the reviewers of a given PR. Multiply that by the number of PRs in flight (one person, one PR) and you get the total number of interruptions in the team.
E.g. if it’s mandatory for at least one person to review a PR and if you have 4 developers in a team, total number of interruptions in the team increases 8 times (4x2). Just for one halving of the PR!
