Spearhead Systems Incident Response Documentation
This documentation covers parts of the Spearhead Systems Issue Response process. It is a copy of PagerDuty's documentation and furthermore a cut-down version of our own internal documentation, used at Spearhead Systems for any issue (incident or service request), and to prepare new employees for on-call responsibilities. It provides information not only on preparing for an incident, but also what to do during and after. It is intended to be used by on-call practitioners and those involved in an operational incident response process (or those wishing to enact a formal incident response process). See the about page for more information on what this documentation is and why it exists. This documentation is complementary to what is available in our existing wiki and may not yet be open sourced.
Issue, Incident and Service Request
At Spearhead we use the term issue to define any request from our customers. Issues fall into two categories: "Service Requests (SR)" and "Incidents (IN)". Note that we use the term Incident to describe both a service request as well as incidents. For brevity we will use SR and IN throughout this documentation.
A "service request" is usually initiated by a human and is generally not critical for the normal functioning of the business while an "incident" is an issue that is or can cause interruption to normal business functions.
