Mandatory — cannot ship without this
Conditional — depends on your specific product
Skip — not relevant for this vertical
Five vertical playbooks. For each: the categories that are mandatory, the ones that are conditional on your specific product, and the ones you can safely ignore. Plus the regulations, the domain-specific pitfalls, and the wins worth chasing.
This is not a generic checklist. Each playbook reflects how that industry buys, regulates, and operates.
