Traditional Manufacturing• Mass Production –
– Uses interchangeable standardized parts that can quickly be assembled
– Breaks complex operations down into simple steps that can be performed by unskilled workers
• A ‘PUSH’ Manufacturing system – Output from the first process in the sequence drives the second process and so on

New Trends in Manufacturing• Lean Production –
– Less of everything is required to produce the same quantity that traditional mass production generated
– Less materials, equipment, manhours, time, effort, capital
• A ‘PULL’ Manufacturing system that is driven by customers orders and need for specific parts

New Trends in Manufacturing• KANBAN • Cards that carry information from one process to
processes that come afterward• Tell about what and how much to produce next.• Identifies the type of part, how many there are, and other
basic information.• “Pulls” only needed parts without maintaining extra inventory

review work procedures– Come up with ways of enhancing their
performance.

other workers of a quality or process problem– Uses a signboard incorporating signal lights to
indicate which workstation has the problem

Push Production• As each person
finishes his/her job, it is pushed to the next person.
Faster production. Increased chance of
error - less quality.
![Page 27: Duration: 3 hours (4 class periods) The Big Idea: Manufacturing is the production of physical goods using a variety of mechanical processes](https://reader035.vdocument.in/reader035/viewer/2022062905/5a4d1af27f8b9ab05997ecc3/html5/thumbnails/27.jpg)
Pull Production• Each person does not
start a new part until their last one has been pulled from them.
Increased quality. Slower production.

Push versus Pull Manufacturing
• PUSH – complete task as quickly as possible– Faster Production (more items made in shorter period of time)– Less quality (more likely to make mistakes)
• PULL – complete task only when the previously completed item is removed or ‘pulled’– Slower production (more likely to have idle time)– Increased quality
