2. Mass production (also called flow production, repetitive flow production, series production, or serial production) is the production of large amounts of standardized products, including and especially on assembly lines.

3. OVERVIEW Mass production of assemblies typically uses electric-motor-powered moving tracks or conveyor belts to move partially complete products to workers, who perform simple repetitive tasks.

4. OVERVIEW Mass production is capital intensive and energy intensive, as it uses a high proportion of machinery and energy in relation to workers.

5. OVERVIEW One of the descriptions of mass production is that the craftsmanship is in the workbenchitself, not the training of the worker; for example, rather than having a skilled worker measure every dimension of each part of the product against the plans or the other parts as it is being formed, there are jigs and gauge blocks that are ready at hand to ensure that the part is made to fit this set-up.

6. Use of Assembly Lines in Mass Production Mass production systems are usually organized into assembly lines. The assemblies pass by on a conveyor, or if they are heavy, hung from an overhead monorail.

7. Advantages and Disadvantages In craft production, the craftsman must bustle about a shop, getting parts and assembling them. He must locate and use many tools many times for varying tasks.

8. Advantages and Disadvantages In mass production, each worker repeats one or a few related tasks that use the same tool to perform identical or near-identical operations on a stream of products.

9. Advantages and Disadvantages The probability of human error and variation is also reduced, as tasks are predominantly carried out by machinery. However, mass production is inflexible because it is difficult to alter a design or production process after a production line is implemented.

10. VERTICAL INTEGRATION Vertical integration is a business practice that involves gaining complete control over a product's production, from raw materials to final assembly.

11. HISTORY Mass production was popularized in the 1910s and 1920s by Henry Ford's Ford Motor Company, which introduced electric motors to the then-well-known technique of chain or sequential production and, in the process, began a new era often called the "second industrial revolution."

12. HISTORY Although the Ford Motor Company brought mass production to new heights, it was a synthesizer and extrapolator of ideas rather than being the first creator of mass production.

13. HISTORY During the American Civil War the Springfield Armory started to mass produce guns, using interchangeable parts on a large scale.

14. HISTORY Taking a look back at the history of American manufacturing, the key features of mass production were the perfect interchangeability of parts in the goods produced, long production runs and large quantity of outputs that were homogeneous.
