Your data displayed is either visible or visual. If the data is displayed and your business is “business as usual” then your data is visible - not visual. If it triggers actions based on gap identification resulting in an improved process then it is visual.
The art of using LSW as an improvement tool is to be able to read the sheet with your "process" eyes. What this means is not to focus on reds and ask "why didn't they get done?" What you are looking for as a lean leader are process gaps.
