If the manufacturer breaks a large component of a machine that is out-dated and the repair spare parts are no longer available in the market but it so happens that the machine is still useful.The manufacturer takes the broken component to the shop where a new machine will be constructed from the beginning. The machine shop is a good example of a work shop which is dedicated to manufacturing.A job shop can therefore be defined as a manufacturer of products that are unique.The product subjected to the job shop has to be of a unique nature requiring a specific approach towards interpreting design by the customer and the specifications. The production of such a product requires unique experience and production skills. When the product design is specified, the responsibility of production shifts to a group of workers, a specified workforce is designated to decide how best to execute the production process. The processing resources in this case are limited in availability.On the other hand, the storage capacity during processing is temporary as the available jobs anticipate processing. Where the product happen not to be a one-time request, then the product is potentially irregular and having lengthy periods occurring between orders of those products. The efficiencyproperty may not be forthcoming because each product output happens with its own merit and treated differently.
The output prescribed in a job shop significantly differs in terms of structure, form, process requirement and materials needed. Each of the jobs goes through a functional area to the next in accordance with the unique routine, different operation requirements, and the time needed for the process. The flow of production is therefore cluttered and following no particular sequential pattern. The batch operations and job shops from the top left matrix quadrant are organised according to the functionalities of the machines in their individual capacities. This means that the machines are categorised depending on the purpose served or the process capabilities possessed. In a job shop, for instance the hydro power machinery would be grouped in a specific shop area, leather products in another area, drilling equipment in another, chemical reactors on another area etc. this classification is commonly referred to as the process layout.
