Common questions
- What is the Measurement layer?
- What happened, and what closes next. It serves Metrics in the eight-layer model of revenue architecture. Forecast accuracy is structural, not a spreadsheet exercise.
- Which tools do operators run in the Measurement layer?
- 4 tools are placed in the Measurement layer, 3 of them named by an operator running them in a working system. The most-named are Gong (2 operators), Consensus (1 operator) and Google Search Console (1 operator).
- How does a tool get placed in the Measurement layer?
- A tool is placed by the function it performed in a named operator's system, described on a Show Me Your Stack or GTM Vault Podcast episode, or by a GTM Vault essay recommendation. The two grades are shown separately and never blended. Placement is not for sale.
