Theory of Constraints states that we should "subordinate everything to the constraint." Given the $6$ step process below to make steel where "Stirring" is the bottleneck, which situation is an example of "subordinate everything to the constraint?" $($Slide $15)$

$1-$ Making the Iron

$2-$ Primary Steel Making

$3-$ Secondary Steel Making

$4-$ Stirring $($BOTTLENECK$)$

$5-$ Continual Casting
