SRE Weekly Issue #507

A message from our sponsor, incident.io:

incident.io lives inside Slack and Microsoft Teams, breaking down emergencies into actionable steps to resolution. Alerts auto-create channels, ping the right people, log actions in real time, and generate postmortems with full context.
Move fast when you break things and stay organized inside the tool your team already uses everyday.

An explanation of the Nemawashi principle for driving buy-in for your initiatives. This is not specifically SRE-targeted, but we so often find ourselves seeking buy-in for our reliability initiatives.

The next time you’re flooded with alerts, ask yourself: Does this metric reflect customer pain, or is it just noise? The answer could change how you approach reliability forever.
