Hi Nirmal -
Are you using the People Analyzer and EOS suggested Annual Review form? I have a client with 22 employees who was considering an HR package at the beginning of their EOS journey, but realized once they started doing Quarterly Conversations and using the People Analyzer, they didn't need the system. In their case, they were looking for the HR system to drive accountability and improve communication -- things they (and other managers) should be doing with their direct reports as part of LMA. What they really needed was the right people in the right seats.
Christine is right that a software package like Ninety.io4 or Traction Tools will help track employee scorecard numbers, as well as your other EOS tools.
Feel free to reach out to me or any other EOS implementer if you'd like to discuss further.
