Which type of production involves manufacturing products according to customer's specifications, with one product being completed before starting another?

The type of production that involves manufacturing products according to customer specifications, with one product being completed before starting another, is job production. This method is characterized by a focus on individual orders and customization. Each product is often unique, designed to meet specific requirements set by the customer.

In job production, the entire production process is tailored to the needs of a single client, meaning that each job can vary significantly in terms of complexity, time taken, and resources required. This method allows for high levels of customization and quality control, as each job is carefully crafted to meet the expectations of the client.

In contrast, other production methods such as batch production involve creating a set quantity of a product before switching to another type, which does not allow for the same level of customization per individual order. Flow production refers to the continuous production of standardized products in large quantities, and mass production focuses on producing vast amounts of identical items, typically resulting in less variation and personalization. Hence, job production stands out for its emphasis on fulfilling unique customer requirements one at a time.
