The four parts
- Event
- What starts the clock — record created, issue raised, milestone due.
- Standard
- The committed time, stated per severity or source.
- Measurement
- Where the clock is read, and what counts as satisfying it. Logging an unanswered call is not contact.
- Consequence
- What happens on breach: who is notified, and what they are expected to do.

Internal SLAs between teams — marketing to sales, sales to delivery, support to engineering — are where most operating value sits, because they make boundary failures visible before a customer experiences them. They also cost nothing contractually, so there is no reason not to define them.
