Continuous data is better than Attribute: for scorecards too

I see many company scorecards as I coach my students.  Well over half of the companies have adopted a red/yellow/green color coding for their scorecards.  Generally they are made with the conditional formatting functions that are in Excel.  I know that the stoplight symbolism is great, but what the scorecards have done is convert a numeric value (continuous data) into an ordinal value (attribute) and they are happy.

As a lean six sigma practitioner, we would never convert our project data from continuous to attribute during our project.  Agree?

So why do we not speak up when our companies do it with scorecards.  Think about it.
