What we examine

Follow the signal.
Check every handoff.

A focused product analytics audit across the layers that shape your numbers.

We agree on the critical journeys, platforms, and decisions upfront. The audit goes deep on that scope; it does not assume every event in your organization needs the same attention.

Events & instrumentation

Missing, duplicated, or incorrect events; properties, identity, and tracking validation.

Funnels & configuration

Journey continuity, analytics settings, and discrepancies across tools such as Amplitude and GA4.

KPIs & dashboards

Metric definitions, filters, calculation logic, and consistency between reports.

Tracking & release QA

How product changes are tested and whether tracking regressions reach production.

Ownership & governance

Who defines, approves, and maintains the metrics and tracking in scope.

A look at the method

One journey.
Several places to lose the truth.

Select a layer to explore an example finding. This is an illustrative audit, using a fictional activation journey.

01 / Product behavior

The action works. The signal is missing.

A user completes onboarding in the app, but the completion event is absent on one mobile release. The product passes a functional test; the funnel still undercounts activation.

What we validate

Trace the completed journey against the emitted events, properties, and release version.

What you take away

Useful to leadership.
Actionable for your team.

Reliability Map

Know what you can trust.

A clear view of reliable signals, uncertain metrics, and the gaps that put decisions at risk.

Prioritized Repair Plan

Fix what matters first.

Findings ranked by business impact and implementation effort, with a practical order of work.

Executive Brief

Give leadership a straight answer.

Which product and business decisions your analytics can safely support — and which need better evidence.

Technical Findings

Move from diagnosis to action.

Specific recommendations for Product, Engineering, and Data teams, grounded in the issues we find.

How the engagement works

A clear scope.
A direct route to answers.

The 7–10 business day audit starts once the agreed access and materials are available.

Review & scope

A 30-minute conversation about the decisions, discrepancies, and journeys that matter. We agree the scope and fee before starting.

Trace & validate

Review the agreed tracking, configurations, reports, and release practices. Reproduce discrepancies and document the evidence.

Readout & next steps

Walk through the findings with your team. You receive the four deliverables and a prioritized path to repair.

Before we begin

A few practical details.

What do you need from our team?

Access to the analytics tools and dashboards in scope, relevant tracking plans and KPI definitions, and a point of contact across Product, Engineering, or Data. We agree the minimum access needed during scoping.

Will you change our production tracking?

The audit is a diagnostic engagement. Implementation is scoped separately through Reliability Repair, with changes agreed before work begins.

Do we need to change analytics platforms?

No. We work with your existing setup, including Amplitude, GA4, Mixpanel, PostHog, Looker, and similar tools. The goal is to make the evidence reliable, not to sell you a replacement stack.

What does the audit cost?

The fee is agreed upfront based on the product journeys, tools, and access requirements in scope. The review conversation helps us define a focused engagement before you commit.

What happens after the audit?

Your team can use the prioritized repair plan independently, or work with Proteus on Reliability Repair and ongoing analytics QA. There is no requirement to continue into another engagement.

Which numbers are you
still second-guessing?

Bring the metric, funnel, or dashboard you’re unsure about. We’ll talk through what’s at stake and whether an audit is the right next step.
