Just launched a PD on PD section in the Ops Guides that might be useful if you're looking to get more out of PagerDuty (or convincing your team to adopt better practices)! We documented how we actually use PagerDuty internally at PagerDuty — the good, the bad, and the "oh that's how they do it" moments. There are 10+ real stories covering different use cases, plus a bunch of best practices we've learned in the process.
When folks ask us "okay but how do you use it?" — it turns out we have a lot to share that is useful for others trying to level up their incident response game or just looking for ideas. Feel free to reply with any questions!
