"Let all your efforts be directed to
something, let it keep that end in view.
It's not activity that disturbs people, but
false conceptions of things that drive
them mad." - Seneca

Incident Lifecycle

Each cycle
reduces impact

PHASE 1
Incident
PHASE 2
Post Incident Review
Experiment
View any post-incident review
processes as a guide to be improved
upon

Input Variables
Emotion
Experience
Exposure
6
Emotion - Why - Quantity
Direct
Received in person by SRE for certain
companies or products
Potential for bias, speed of collation is high.
Translated
Through anothers experience, an interview or
support ticket.
Reduced impact of bias but slow for collation
7
Experience - How - Quality
Challenger
Seeks to insert an individual to raise the quality
after the PIR
Requires additional training and trainers to
generate challenger pool
Does not scale
Split Streams
Seeks to parallelise PIR construction through
multiple contributors
Requires co-ordinator and training - significant
overhead on each deployment
Scales after initial investment
8
Exposure - What - Distribution
External
Remain aware of issues affecting companies or
the more broader incident space
Difficult in construction if details and impact of
original incident are unclear
Internal
Understand other teams similarities yet
removal from original remediation items
Requires investment with no impact realised
Needs careful selection for participation
