ISO 20000 is, quietly, the ISO standard most aligned with opportunity-based thinking. Its continual service improvement (CSI) loop already assumes that improvements are identified, prioritized and pursued. Wiring OBT into a 20000 environment is less a transplant than a clarification.
Where 20000 already does the work
The CSI register, when it exists, is functionally an opportunity register under another name. Service-level review meetings produce candidate improvements that are scored, owned and reviewed — exactly the OBT shape.
Where it stops short
Most CSI registers focus on 'fix what is below SLA' improvements — restorative, not opportunity-seeking. The bar is the SLA; nothing in the artifact prompts entries that exceed it.
A worked example: the latency band
A managed-services provider met its 95th-percentile latency SLA with margin. A standard CSI review would have noted the green status and moved on. With the direction field in place, the entry became opportunistic: 'Tighten internal latency target by 30% and offer a premium SLA tier.'
Within two quarters, three customers had signed onto the new tier. The SLA the provider was already meeting became a product.
“The opportunity was not the latency. It was the unsold margin between the SLA and reality.”
