Reliability Has a Price Tag
Every “nine” in your SLA isn’t free — it’s a bill waiting for approval. SLOs and SLIs make reliability measurable, and error budgets turn it into a planning tool, not a guess.
What works in practice:
Price each extra nine like an investment line.
Use error budgets as signals for product velocity.
Put reliability on the exec dashboard next to revenue and churn.
How many “nines” do your customers actually pay for?
