This is the correct answer. For extra credit: if you have a weekly or monthly team meeting, include an agenda item for the people that were on call so they can debrief the team on what alerts fired and what the resolutions were. As a team, you can then decide which alerts need to be deleted or need adjustments, and if there are additions or edits that need to be made to the runbook. A big thing to avoid in this whole process is "naming and shaming." The Google SRE book calls this a "blameless postmortem culture," and it's helps you avoid perverse incentives for people to hide or obscure latent production issues.
