Page 3: Real lean transition case for a clothing company english daha-iyisini-yapabilirmiyiz.blogspot.com.tr

Why to change ?• High finished goods inventory – avg. 5 weeks• High WIP – avg. 3 weeks• High raw material inventory – avg. 4 weeks

RESULTS:

(a) excessive finance charges

(b) contribution towards slow selling lines and raw material write-offs

(c) lack of flexibility - not serving customers’ needs

(d) poor profit performance.
