THE GOAL KEY TAKEAWAYS

• Bottleneck constrain capacity

o  They are the result of material shortages, machine’s standing idle,

poor workow, inecient use of labor, worker training problemso Problems: Orders being lled late

Key Takeaways:

1. The goal of any manufacturing operation is to earn a prot 

2. One measure of protability is Throughput a! Throughput the amount of product mo"ed through the plant

3. Second measurement of protability: Inventory a! #$cess %n"entory costs:

i! &oney paid to purchase in"entory which then sits idleii! %t takes space to store in"entory, there is an opportunity cost

associated with thisiii! #mployee tracking and handling

 . Third measure of protability: Operational !"pensea! 'ost of materialsb! &achine repair costsc! #nergy costsd! (abour costse! )e"en *astes that a factory should eliminate:

i! O"erproductionii! *ait timeiii! +nnecessary transportation of materialsi"! +se of complicated high cost euipment"! #$cess in"entory

"i! +nnecessary physical motions"ii! Too many defecti"e products

#. $a%or impediment to factory is bottlenec& or constraint a! 'auses of bottlenecks

i! (ess than adeuate materials reaching the process -arri"al time.ii! #mployee delay setting up euipmentiii! #uipment breaking

i! Prioriti3ing orders so workers would handle the most pressing

ones rst

 

ii! 4e5arranging the workers lunch schedule so the machine would
