You can embrace lean in different ways. You can make use of Lean tools, you can attend lean courses and you can embrace Lean values  (Toyota production system "TPS"  to be correct).

But how do you know you are a Lean organisation?

  1. You define value from the eyes of the end customer
  2. You have a value stream/process to deliver this
  3. Management is continuously decreasing the Lead time across that value stream

I will give the reason for each..
