Problems

• Data team is not familiar with implementation details
• Dev team lacks guidance on metrics
• Project owners cannot easily explore the collected data

Maintainability

• Raw string in code base
• Not easy to modify

Standardization

• No document
• No spec

basic workflow

• data team & project owner: define metrics & specs with product owners

• data team: write events and specs into code (config) for FE to reference

• FE dev: use the specs to implement

• FE dev & data team: send PR and data team review

• data team: set up funnels/dashboards etc and send them to project owner

Tracking plan

Feels good

Spec

• Human readable configuration file
• Event name
• Description
• etc.

Library

• A Gem library for backend
• A Js library for frontend

IR

• Intermediate representation
• Generate from spec and feed it to the library
• Compression intent mostly
• Evaluate if we really need it
