Just in time (JIT)
• A production strategy used to improve business by reducing in-process inventory
• Based on the philosophy: Inventory is waste
• A shift away from the older “Just In Case” strategy
![Page 13: Inventory mgmt n jit](https://reader033.fdocuments.us/reader033/viewer/2022061221/54bd846a4a7959fd368b456a/html5/thumbnails/13.jpg)
Definition
“Just In Time is an inventory strategy which companies employ to increase efficiency and decrease waste by receiving goods
only as they are needed in the production process, thereby reducing inventory costs.This method requires that producers are
able to accurately forecast demand.”
![Page 14: Inventory mgmt n jit](https://reader033.fdocuments.us/reader033/viewer/2022061221/54bd846a4a7959fd368b456a/html5/thumbnails/14.jpg)
KANBAN Literally means “signboard” or “billboard”
Created by Taiichi Ohno
It is not an inventory control system but a scheduling system
It uses the rate of demand to control the rate of production
![Page 15: Inventory mgmt n jit](https://reader033.fdocuments.us/reader033/viewer/2022061221/54bd846a4a7959fd368b456a/html5/thumbnails/15.jpg)
DEFINITION
“A specific type of inventory control system. The kanban system is based upon a series of colored
cards. These cards denote such factors as quantity, the type of part and the manufacturer. A card is placed in the bin or other container with each
group of manufactured items as an identifier for those involved with the next phase of production
or distribution.”

EFFECTS OF JIT
![Page 37: Inventory mgmt n jit](https://reader033.fdocuments.us/reader033/viewer/2022061221/54bd846a4a7959fd368b456a/html5/thumbnails/37.jpg)
In some cases, company eliminated multiple suppliers.
It has been widely emulated, but not always with the expected results, as many firms failed to adopt the full system. The just-in-time philosophy was also applied to other segments of the supply chain in several types of industries.
![Page 38: Inventory mgmt n jit](https://reader033.fdocuments.us/reader033/viewer/2022061221/54bd846a4a7959fd368b456a/html5/thumbnails/38.jpg)
Reduced setup time
The flow of goods from warehouse to shelves improves
Employees with multiple skills are used more efficiently.
Increased emphasis on supplier relationships.
BENEFITS OF JIT
![Page 39: Inventory mgmt n jit](https://reader033.fdocuments.us/reader033/viewer/2022061221/54bd846a4a7959fd368b456a/html5/thumbnails/39.jpg)
Production scheduling and work hour consistency synchronized with demand.
Supplies come in at regular intervals throughout the production day.
Minimizes storage space needed.
Smaller chance of inventory breaking/expiring
![Page 40: Inventory mgmt n jit](https://reader033.fdocuments.us/reader033/viewer/2022061221/54bd846a4a7959fd368b456a/html5/thumbnails/40.jpg)
BUSINESS MODELS FOLLOWING SIMILAR APPROACH
• VENDOR-MANAGED INVENTORY
Same principles as those of JIT inventory
Manager of inventory- vendor
Industry experience and expertise
Inventory cost on the vendor's books
![Page 41: Inventory mgmt n jit](https://reader033.fdocuments.us/reader033/viewer/2022061221/54bd846a4a7959fd368b456a/html5/thumbnails/41.jpg)

• CUSTOMER-MANAGED INVENTORY
Customer has responsibility
for all inventory decisions
• EARLY USE OF A JIT SYSTEM
A type of JIT was used successfully
in the UK by Perkins to supply F3
engines to Ford from 1957 until 1964.
![Page 43: Inventory mgmt n jit](https://reader033.fdocuments.us/reader033/viewer/2022061221/54bd846a4a7959fd368b456a/html5/thumbnails/43.jpg)
CONCLUSION• In JIT workers are multifunctional.
• Multifunction machines, U-shaped cells.
• Environment is clean and free of waste
• The "PULL" element of JIT
JIT has truly changed the face of manufacturing and transformed the global economy. JIT is both a philosophy and collection of management methods and techniques used to eliminate waste (particularly inventory).
