Dan Herd

Principal Site Reliability Engineer Dunelm

CONFERENCE DAY ONE

12:00 PM Panel Discussion - What Does SRE Mean Now? The Enterprise Interpretation

Most organisations adopt SRE principles without adopting the "classic" model - and that's often the right call. The challenge is avoiding confusion, bottlenecks, and "SRE as the dumping ground" by agreeing what SRE is there to enable.

• Agreeing SRE's purpose: enablement, shared ownership, or embedded support

• Using SLOs to prioritise work without turning reliability into politics

• Designing on-call boundaries so accountability is clear and scalable

CONFERENCE DAY TWO

2:00 PM Presentation: OTel Me More: Dunelm's Journey to OpenTelemetry

Dunelm operates 200+ stores, a fast growing e commerce site, and high traffic mobile apps, so diagnosing issues across systems was anything but straightforward. With inconsistent instrumentation, patchy visibility, and rising observability costs, something had to change. Dan Herd shares how Dunelm tackled the chaos by embracing OpenTelemetry end to end and building a custom service that transforms CDN logs into spans, giving the business a clean, connected view from front end to back end and how adopting a true product mindset helped win over engineering teams.

• Streamlining telemetry through a unified OpenTelemetry pipeline and consistent service instrumentation

• Optimising performance, cost, and reliability across functions, platforms, and high traffic systems

• Connecting front end to back end observability with custom span generation and a strong product first approach
