Dore Dore Case study - Solutions:

1. Evaluate the Changes Dore Dore has made in its Children’s Knitwear division.

* Children Knitwear Traditional setup (Product – Focused Layout) * Children Knitwear cellular setup (Process – Focused Layout)

Traditional Operations:

Yam & Fabric supplier – 2.5 months – average lead time
Knitting – throughput time – 80 hrs
Dyeing – 5 weeks – average lead time
Cutting – 40 hrs – throughput time
Sewing and finishing – 120 hrs – throughput time
Lead time & Throughput time – batch size = 200 units
Bottle neck operation is sewing & finishing.

Work in progress calculations:

Units progress / day = 2000 units
Through put time = 15 days
WIP = 2000 *15=30000 Units
No of workers = 42
