# Rolling Out OpenTelemetry — OpenTelemetry

> Incremental adoption.

## Start small, standardise, expand

Begin with one critical user journey across a few services: deploy a Collector, enable zero-code instrumentation, verify end-to-end traces and context propagation, and connect a backend. Agree on standards early: service naming, resource attributes, sampling policy and attribute conventions. Add manual spans for business-critical paths, connect logs, then expand team by team. Provide shared configuration (a base Collector config, an internal library or environment variable defaults) so every service is consistent.

## Wiring a building floor by floor

Electricians agree on plug standards first, then wire one floor, test it, and repeat; they do not rewire the whole building at once.

## Measure success by faster investigations

Track time to find the cause of incidents before and after adoption to show value.

**Quiz:** What is a sensible first step when adopting OpenTelemetry?

- [ ] Choose sampling after a year
- [ ] Instrument every service manually at once
- [x] Instrument one critical user journey end to end and verify propagation
- [ ] Skip the Collector and resource attributes

*Answer:* Instrument one critical user journey end to end and verify propagation. Prove value on a slice first.
