The best thing about this guide is that it is free and has no gate on it, which sounds like faint praise and is not. The incident management category is full of material that requires an email address, a job title and a company size before it will tell you anything, and the resulting content is usually thin because its purpose was lead capture rather than instruction. incident.io has put a substantial body of writing out in the open, and my experience of the industry is that content published without a gate tends to be better, because it has to earn attention rather than merely be exchanged for it. The on-call material is the strongest section and the one I would send people to first.
Most writing about on-call is either a technical description of rotation mechanics or a set of platitudes about work-life balance. This engages with the actual design questions that determine whether an on-call rotation is sustainable or corrosive. How large does a rotation need to be before the burden is bearable, and what happens below that number. What compensation, in money or time, acknowledges that being tethered to a laptop for a week is a real imposition even when nothing pages.
What the handover between shifts should contain so that the incoming engineer is not starting cold. How to decide what is genuinely worth waking a human for at three in the morning versus what can wait until business hours, and who is empowered to make that call. These are the questions that decide whether your best engineers stay, and they are treated here as design problems with trade-offs rather than as an HR concern. That framing is right and it is rare.
The organisation-wide angle is the other distinctive contribution. Most incident literature is written by and for engineers, and consequently treats an incident as a technical event with some communication attached. The reality at any company past a certain size is that a significant incident involves support, who are absorbing customer contact, communications, who own the public statement, legal and compliance, who need to know whether anything triggers a notification obligation, sales, who have customers asking, and an executive who wants a number. Treating those functions as participants with defined roles rather than as interruptions to be managed is a meaningful improvement over the engineering-only view, and it maps to how incidents genuinely unfold.
I appreciated the reading list as well, which points outward to other sources including public post-mortem databases where you can read real incident write-ups from real companies. Recommending things that are not yours is a small signal of intellectual honesty and most vendor content does not do it. The criticisms. Alert fatigue is handled more gently than it deserves, and this is the structural problem I have now identified for every incident and paging vendor in this catalogue: a company whose product is the routing of alerts to humans has no commercial incentive to teach you to generate dramatically fewer alerts.
The guide acknowledges alert quality as a topic. It does not make the argument it should make, which is that the overwhelming majority of on-call misery is caused by alerting on conditions that do not require a human to be awake, that the correct response to a noisy alert is usually to delete it rather than to tune it, and that an organisation should treat its page volume as a defect count to be driven toward zero. That is the argument that would most improve most readers' lives, and no vendor in this market will make it forcefully. The tonal drift is a smaller issue but worth flagging for a careful reader.
The guide moves between general doctrine and product positioning without signalling the transition, so a section that begins as a description of how incident response should work can arrive at a workflow that resembles a particular product's model rather closely. Nothing dishonest is happening, but a reader taking notes should stay alert to which claims are principles and which are implementations. The metrics guidance leans toward the conventional measures, which have a well-known problem: mean time to resolution is trivially improved by classifying more small incidents as incidents, incident counts drop when people stop declaring, and any metric attached to an individual's performance will corrupt the reporting culture that makes incident management work at all. A stronger treatment would warn harder about this.
Finally, this is reading, not practice. The doctrine is the easy part and every engineer who has read it still freezes the first time they are incident commander for something serious. Pair the reading with drills, whether from Rootly Academy, an internal game day programme or simply a monthly exercise someone volunteers to run. Four point one.
Free, ungated, genuinely thoughtful on the human dimension that most incident writing ignores, held back by the alert fatigue silence that the business model makes inevitable and by being prose rather than practice.
