Business Landscape - C4 Level 1
The view from outside. Who interacts with Olly and which business capabilities they reach. No central "Olly Platform" box, no infrastructure, no delivery details - just the actors, the capabilities, and the two clinical externals that matter at the business level.

Actors
| Actor | What they do | Where they meet Olly |

Business capabilities
| Capability | Purpose |
|---|---|
| Triage & Care | AI-led symptom triage + disposition + care-pathway booking. |
| Membership & Enrolment | Who is covered, on what plan, under whose scheme. Eligibility + consent. |
| Claims & Adjudication | Claim intake → rules → decision. Prior auth lives here. |
| Billing & Premium Collection | Invoicing, premium collection, dunning, payouts. |
| Provider Network | Directory, credentialing, contracts. |
| Brokerage | Quote / bind / commission for distribution partners. |
| Member Experience | The consumer touchpoints - portal, mobile, AI chat, notifications. |
True externals (clinical only)
| External | Why we cross the boundary |
|---|---|
| NHS / Public Healthcare | UK public healthcare. Pathway/clinical-guideline data; provider funding context. |
| Provider EHRs | Clinical record exchange. FHIR / HL7 in both directions. |
What's deliberately not here
These exist but don't belong at L1:
- Platform Infrastructure (APISIX, Postgres, Kafka, Keycloak, OpenBao, Temporal, GrowthBook, Novu, Mirth, OpenSearch, observability, Admin Console, MCP Server) - shared rails, see L2 → Platform Infrastructure. (A Snowflake analytics warehouse is a target-state item, not deployed - see L2 → Billing.)
- Auxiliary delivery externals (Email Provider, Google Gemini / LLM, Clearinghouses, Payment Rails) - appear in Business Processes where the flow needs them, not as first-class L1 entities.
