We’ll start with some background information, including definitions, incident management framework, and existing preventive techniques, aka best practices. Followed by details and rationale around individual categories, sub-categories, and their relative distribution.

Finally, we’ll discuss the propagation of lessons learned in terms of policy and process changes based on these insights.
