@Gal Erez6 That's a great question! I agree with Jerry - the organizational check-up is helpful and you can track progress every time you retake the check-up.
As the self-implementer of EOS at Teamwork, I built myself a so-called "EOS Tracker", where I measure the adoption of each foundational tool per LMA function in our business. This provides me with an overall adoption score for each foundational tool (V/TO, Scorecards, Acc. Chart, People Analyzer, etc.) and the average adoption score for all tools - see below:
There might be better ways of doing this...would love to hear other opinions.
