We go to LT reduction, because<br />
• It leads to the ability of agile responsiveness .<br />
• It decreases <strong>in</strong>ventory.<br />
TOCICO 2009 Conference<br />
• It is easy to set the goal of improvement activities.<br />
• TOC-DBR and TOC-Replenishment teaches us to<br />
focus on it.<br />
