Income, Revenue_USD, Revenue_new, rev2, customer_revenue. Do you acknowledge these? They may be the column names you would possibly discover in your BI or analytics software. Which is the one to make use of?
You choose Revenue_new (it’s new, in spite of everything!) and proceed together with your evaluation. A couple of minutes into the assembly with the gross sales workforce, the group startles: the information doesn’t match their expectations.
One thing’s flawed.
What knowledge are you utilizing?! Revenue_new? Oh, Revenue_new is the previous column. The corporate moved to customer_revenue final quarter once we employed a brand new VP of Finance and so they up to date the definition.
Airbnb confronted this downside, too.
Circa 2010, there was just one full-time analyst on the firm engaged on knowledge, and his laptop computer was successfully the corporate’s knowledge warehouse. Queries have been usually run immediately towards the manufacturing databases, and costly queries often brought about severe incidents and took down Airbnb.com.
As the corporate grew, issues worsened:
Years in the past, when Brian, our CEO, would ask easy questions like which metropolis had essentially the most bookings within the earlier week, Knowledge Science and Finance would generally present diverging solutions utilizing barely totally different tables, metric definitions, and enterprise logic.
So Airbnb constructed an inner product Minerva to unravel these issues. Minerva is ubiquitous inside Airbnb – it manages greater than 12,000 metrics and 4,000 dimensions throughout 200 knowledge producers.
MetricFlow is an open-source Minerva.
With MetricFlow, a consumer can seek for metrics, discover the one accepted by the outgoing VP Finance, obtain a notification when the brand new VPF updates it, see the calculation, and determine the metric’s proprietor.
MetricFlow and Minerva are helpful for BI, however they do extra. Groups can construct on them as a platform.
Think about the shopper success workforce asks for a income chart of their CRM: it’s as simple as siphoning the information from MetricsFlow through a API name. The software program is future proofed. If the definition modifications, so do the charts. Updates cascade by way of the group.
Right here’s a demo that goes right into a bit extra element.
Within the two weeks since launch, MetricFlow has grown to greater than 400 Github stars, and is now the most well-liked metrics framework by that commonplace.
In case you’re inquisitive about metrics shops and the way they match into the fashionable knowledge stack and knowledge mesh, you may be to attend the primary Metric Retailer Summit subsequent week the place folks from Spotify, Airbnb, Mode, and Hex shall be discussing them.
The title of this publish is a play on phrases from Coleridge’s Rime of the Historic Mariner. Dangerous metrics are like salt water. Not a lot use to a sailor or an analyst.
