Telemetry Instrumentation Review

Overview

Inaccurate retention data almost always stems from corrupted telemetry. As development teams ship rapid feature releases, event names drift, payload keys are omitted, and session boundaries break.

The Telemetry Instrumentation Review is an engineering-first evaluation that inspects your application’s event emission pipeline. We audit how events are defined, formatted, and transmitted from client applications (iOS, Android, React Native, Flutter, Web) to your analytical ingestion layer.

Core Audit Components

1. Event Taxonomy & Naming Standardization

We examine your entire event catalog to eliminate duplicate triggers, ambiguous event verbs, and inconsistent casing. We establish a clean Object-Action naming standard (e.g., checkout_flow_started instead of Clicked_Buy_Now_v2).

2. Payload Schema Validation

We verify that essential context properties (such as user_id, session_id, app_version, subscription_tier, and timestamp_utc) are consistently present across all emitted payloads without silent null-value failures.

3. Client-Side Lifecycle Triggers

We audit critical backgrounding, foregrounding, session timeout, and deep-link attribution events to ensure accurate session duration and cohort segmentation calculations.

Deliverables

• Clean Event Dictionary: A comprehensive, standardized taxonomy matrix formatted for immediate import into your tracking plan or analytics workspace.
• Schema Defect Log: A prioritized catalog of identified tracking bugs, missing payload fields, and platform discrepancies.
• Engineering Implementation Guide: Concrete code patterns and schema validation rules to prevent future tracking regression.
• 90-Minute Technical Handover Session: A collaborative review session with your development leads.

Pricing & Requirements

The Telemetry Instrumentation Review is priced at $4,800 USD as a fixed 2-week sprint. Standard kickoff requires access to your event dictionary and sample JSON payloads from production logs.
