A simple form created for the incident management sheet allows inputs for notifications from a desktop, mobile phone, or tablet. No user license is necessary to be able to use the input form meaning you can deploy to anyone involved in any activity with your organization.
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.
