Previously, management calculated the number of kanban cards allowed by using a value of 1.3 for X. Assuming nothing else (e.g., usage rates, container capacities, etc.), which of the following values for X would indicate management's belief that the system has become more efficient?
When a system is created and the value of the system is established, e.g, 1.3; a decrease in the value of the system shows that the system is becoming more efficient, hence the value becomes 1.2.
