The 10 BASE-100 Domains.
Every commercial entity operates across these 10 domains. Each domain has a formal framework name and a practical everyday name, the one you use on your org chart, email aliases, and conversations with the outside world.
Domains are not departments.
A domain is a universal area of business activity. Every commercial entity has all ten, whether it has named them or not. A department is an organizational choice: a box on your org chart, a budget line, a team.
The two are not the same, and the gap between them changes with company size.
In a small company, one person or one department often carries multiple domains. The owner who closes deals, manages the bookkeeper, and approves website copy may touch Revenue and Sales, Finance and Risk, and Brand and Market in the same hour. That is normal at small scale.
In a large company, one domain can span several departments. Finance and Risk might include a CFO office, treasury, risk committee, and compliance team.
BASE-100 measures the domain, not the department. The score reflects how well the activity is defined, owned, measured, and improving, no matter how many people carry it.
This is what makes the framework scale: the same ten domains apply to a two-person startup and a five-hundred-person enterprise. The org chart changes. The domains do not.
One domain, one department.
When a mid-size company is ready to give each domain its own department, this is the conventional mapping. Department names, public-facing email aliases, and the BASE-100 domain they correspond to.
| Code | Domain | Department name | Public email |
|---|
Operations may be labeled Production in event, installation, or physical-delivery businesses. Other names are defaults. Adapt them to your sector.
