My team does Wednesday to Wednesday for many of the same reasons mentioned in the article, and it works great. We switch at 11am and hold a hand-off meeting at that time, and invite the whole team.

Hand-off meetings with the whole team work really well (in my opinion!) when you have a relatively small team--we have 9 FT teammates. Often someone else may have been delegated the page or bug that arose and can discuss how they handled it, or someone who wasn't involved may have insight for how to handle a situation better the next time. Since we're all going to be on rotation at least once during a quarter, it's great to know what happened in case a similar page pops up later.

Finally, we also fill out a running Doc before/during the meeting with links to the pages/bugs, along with short descriptions of how they were handled. This forms a great living memory of how to deal with incidents, and is also often the birthplace of new playbooks for handling new types of incidents.

Same here. Except we do a two week rotation, and it aligns with our sprints. The active on-call engineer doesn’t have any assigned sprint work and focuses their effort on fixing bugs or cleaning up the backlog when they’re not actively triaging an incident.
