CSM KPIs to show success to internal stakeholders

Hi everyone,

At my organization, we're exploring how best to show the value (tangible and intangible) that our CSMs bring to the business. Like most SaaS companies it's easier to show how teams like Sales or Renewals are fairing as it's cold hard dollars arriving, but it's more challenging to show CSM functions success.

We have the usual metrics around NRR, ARR managed per CSM, NPS achieved, expansion $ delivered, case studies etc., but keen to understand how others show the value of their teams to the higher-ups in Finance, Operations and HR and especially how these metrics can support requests for growing headcount.

What would you have on a department-level scorecard to show how well your function is performing?
