DISCRETE UNIT MANUFACTURING and PROCESS MANUFACTURING are at opposite ends of the possible approaches to product-focused manufacturing.
1) How are they different?
2) What are the advantages and disadvantages of each?
3) Which type of manufacturing approach was used first?
4) What types of businesses would use discrete unit manufacturing?
5) What type of business would use process manufacturing?
6) What type of business might use both approaches to manufacturing?

DISCRETE UNIT MANUFACTURING PROCESS MANUFACTURING
1.
• Discrete Unit manufacturing is a manufacturing environment characterized by individual, separate unit production, low in volume, high in product complexity.
• Lead times are variable for different specification products. 1.
• Production environment that adds value by mixing, separating, and/or performing chemical reactions.
• The production process can be done in either a batch or uninterrupted continuous manner.
• Key characteristics include use of ingredient recipes, yield measurement, and Bi-products.
2.
• As there is a great variety in the kind of work to be done, the equipments should be flexible.
• Skill level of workers is relatively high because of variety of work to be done.
• Investment in machines and specialized tooling is low compared to process manufacturing. 2.
• Very high production rate but fixed products. Thus, equipments are completely dedicated for producing a particular product.
• Skill level required is not very high.
• Investment in machines and specialized tooling is high.
3. Traditionally Discrete unit manufacturing was used. Then later on the process manufacturing came in to existence.

4. Computers, Automobiles, Furniture, Ships etc 5. Oil, Gas, Food products, Plastic molded products
6. Computers and automobiles can use both approaches to manufacturing. Up to sub assembly levels, the process manufacturing can be used and for final assembly, Discrete Unit manufacturing approach can be used.
