Managing Processes

Advantages of mass production

-Labor costs are usually lower. -Materials can be purchased in large quantities, so they are often cheaper. -Goods are produced in large number, lowering unit costs.

Disadvantages of mass production

-Machinery is very expensive to buy, so production lines are very expensive to set up. -Workers are not very motivated, since their work is very repetitive. -Production lines are not very flexible and are difficult to change. -Production processes are at risk if any one part of the line breaks. The entire production process will have to stop, pending repair which causes expensive delays. -Maintenance costs are very high.

Facility Location key factors

-Proximity to customers, suppliers, and skilled labor -Environmental regulations -Financial incentives offered by state and local development authorities -Quality-of-life considerations -Potential for future expansion

Advantages of project based production

-Unique, high quality products are made. -Workers are often more motivated and take pride in their work. -Products are made according to individual customer needs and improve customer satisfaction. -Production is easy to organize.

Advantages of batch production

-Unit costs are lower since larger numbers are made. -Customers are offered some variety and choice. -Materials can be bought in bulk, so they are less expensive. -Production is flexible since different batches are made. -Workers specialize in one process.

Disadvantages

-Very labor-intensive, so selling prices are usually higher. -Production can take a long time and can have higher production cost, (e.g., if special materials or tools are required).

Disadvantages of batch production

-Workers are often less motivated because the work becomes repetitive. -Set-up costs are initially high. -Products are expensive to move around the workplace. -Storage space will be needed to store raw materials.
