Recognize your operation in these 8 wastes?
In some organizations, as much as 40% of the
production effort is spent on these wasteful activities.
How much of your time do you spend fighting the fires,
expediting parts, or other activities which do not help
reduce the waste in your operation?
Employees, managers, executives, and corporate
investors will all succeed when the 8 Wastes are
identified and removed.
