Discovery/Maps and KPIs 2015-09-14

=Context= This meeting was in response to concerns raised during the Discovery departmental retrospective, regarding what we are tracking for maps, and how that information relates to the KPIs.

=Existing ambiguities we might need to discuss:= =Discussion=
 * Session tracking
 * Sampling rates: Mix of per-user and per-action? ** All per-action, so resolved.
 * KPIs have been cut down to just 3. One easy to track, one sessions, and one [didn't catch this]

Session tracking

 * KPIs were originally written with sessions in mind. Implementing sessions was difficult, so fell back to actions.
 * Logging by actions is a reasonable starting point. It's not ideal because we can't really understand usage as well.
 * e.g. Can't differentiate between one heavy user and a lot of light users
 * Don't have to block on this.
 * What is the technical hurdle to tracking sessions?
 * We would have to do it through EL.
 * We could keep existing schema, but add a schema with sampling to track sessions.
 * Works because we would only session-track mapping events, not all events.
 * Session = continuous series of browsing. A gap of one hour empirically marks the end of a session.
 * We pick a sample of users, and track page views and maps events with a short-expiry cookie
 * Can show "proportion of sessions that include a map session"
 * What are the benefits of tracking sessiosn vs. just tracking users. Why do we need it?
 * "Reasons".
 * As an organization, for a variety of reasons, we standardized on session tracking, so we'll go with it.
 * prerequisites for session tracking is the same as user tracking, so could switch later
 * Whatever we pick as our initial design/implementation, it can change over time.

Blockers to announcing maps

 * T: When can we see early data from what has already been deployed?
 * O: "By end of tomorrow"
 * Dashboards are already up, showing real data. Tracking usage by platform.
 * Several loose ends need to be tidied before we can call it done
 * T: When could I send announcement?
 * O: Would suggest Tuesday afternoon, or Wednesday morning
 * T: Max and Yuri should be available for the announcement, to handle any incoming questions
 * M: Either should be fine (<--paraphrasing)

=Action Items=
 * Oliver will document his proposal in phab
 * Oliver will create a phab to document pros/cons of session tracking and user tracking (and action tracking?)
