Playbook
In plain terms
A collection of strategies or automated procedures for scenarios.
Going deeper
A playbook outlines coordinated responses to situations, in DevOps often automated (e.g., Ansible playbooks) or for incident handling. It guides repeatable action.
Under the hood
In Ansible it's a YAML automation script; in operations it's a strategic response guide.
Examples
Ansible playbooks, incident playbooks, security response, automation scripts.

Like a sports team's set of practiced plays for different game situations.
