Product KPI Dashboard

What: [KPI Dashboard](https://docs.google.com/spreadsheets/d/1TX6AL-rYN_bHyXS0lAAsq5Mk_CvYiwkBiCBKHoQ_aXk/edit#gid=967850478)

Why:

1. ***Allows for experimentation —*** By tracking individual usage metrics, we are able to understand if our efforts are having any effect and allows us to experiment with small changes.
2. ***May signal problem or bugs —*** Sudden and unexplainable drops in KPIs is a lagging indicator that something is amiss. Without this visibility, we simply may never find out that something is broken.
3. ***Understanding user behavior —*** Tracking KPIs allow us to better understand our users as a whole and may signal usage patterns that help us understand behavior or motivations.

Review the linked KPI Dashboard spreadsheet and the issue's rationale first. The issue does not name repository files, tests, an implementation entry point, or criteria that define when the dashboard is complete.
