What is difference between lean production and mass production?

∙ 14y ago
The difference between the two is that batch productions is a form of production that is applied to a large number of items all at once whilst mass production is the same but made one at a time from mass produced parts.

∙ 14y agoHere are the main differences (but there are some more):
- Mass Production (MP) produces in lots (batches) as large in size as possible - Lean Production (LP) produces in much smaller lots, or more frequent small lots, just as the market wants.
- MP is generally geared to refill (and keep well stocked) the Finished Product warehouse - LP is geared to despatch the output product straight to clients
In MP, Manufacturing Cycle Time and Selling Cycle Time are generally two well distinct issues - in LP the ideal target is to make them coincide. LP motto: "produce today what your customers ordered yesterday and despatch it today or tomorrow at the latest!". LP is generally performed at a speed/pace equivalent to the TAKT TIME.
- In MP Production Planning is generally by means of MRP/ERP systems, complex and time consuming (often also inaccurate) - in LP Production is planned by the customer and pulled (triggered) by the market.
- Therefore, generally, MP is a PUSH type of production - LP is a PULL type of production
- MP is generally accomplished using bulky, General Purpose, expensive and rather difficult to operate Machinery/Technology - LP is generally accomplished using compact, dedicated, quality-geared, easy to move, easy to operate, easy to set up, less expensive equipment.
- MP is generally performed in a Vertical (Job-Shop) type of layout - LP is generally performed in a Horizontal (Flow-Shop) type of layout
- MP generally is associated with considerable surrounding waste (moving - parking - stockpiling - checking - controlling - idling - etc.) - LP targets at a waste-freetype of operations
- MP represented the philosophy of the 1st Industrial Revolution - LP represents the philosophy of the 2nd Industrial Revolution

What is lean production and the importance of lean production?
Lean Production is a well consolidated style of production, mostly related to the Manufacturing Industry.Lean Production is often called Lean Manufacturing.In a nutshell:Lean Production is "lean" because it has no "fat", where fat is "waste". Therefore Lean Production is synonymous with "waste-less" production.Why is it important?Because Lean Production is a primary target for today's manufacturing industry: for survival, competitiveness and excellence.Lean Production uses much less space - takes much less time - originates much less errors and defects - consumes much less resources - and satisfies customers much more compared to traditional "mass production" (batch production - lot production).
What is the difference between one off batch mass and continuous production?
one off is the production of an item once, batch productions is a form of production that is applied to a large number of items all at once whilst mass production is the same but made one at a time from mass produced parts. Haven't heard of continuous production!

How can lean manufacturing and near-sourcing help a company gain a competitive edge and prepare for the future?
Lean ManufacturingLean manufacturing is the production of goods using less of everything than in mass production: less human effort, less manufacturing space, less investment in tools, and less engineering time to develop a new product. A company becomes lean by continuously increasing its capacity to produce high-quality goods while decreasing its need for resources.23 Here are some characteristics of lean companies:24 lean manufacturingThe production of goods using less of everything compared to mass production.
