Jidoka: (a Japanese/Lean word) - the automatic stopping or adjustment of a production line when a non-conforming unit or other problem is detected. "Ji" means the production operator himself; "do" means motion, or work; and "ka" is a Japanese suffix used to complete the word. Jidoka has been termed automation with a human mind - the welding of human intelligence to a machine.

Job Evaluation: The general procedure in both commerce and industry through which the pay of staff is determined is first to determine the rates of pay to apply to the company's jobs, and then to assign staff to the various jobs - that is, strictly, a person's rate of pay is decided indirectly, not offered directly. There are two basic methods for evaluating a job so as to be able to allocate to it a rate of pay: qualitatively and quantitatively. Qualitative job evaluation means regarding the job in its entirety, and then assigning to it a grade based on one of three methods - ranking, classification or market pricing. See separate Glossary headings under these three entries. Quantitative evaluation requires that the demands of the job be analysed from such distinct viewpoints as the need for original thinking; the requirement to assume responsibility; the need to apply manual skill etc., and then assigning to each such facet a certain number of points, to arrive at a job score. The job score is then translated to a pay rate. The two quantitative techniques are point-factor and factor comparison.
Job Grading: See Classification of Jobs.
Job Lot: An individual batch of components, usually associated with a specific works order, the batch of components always being identified and handled as a group.
Job Score: See Job Evaluation.
Job Shop: A plant or shop floor given over to the manufacture of individual works orders, usually on a once-off basis. All work undertaken in the job shop is thus unique, or, at least, is individually undertaken. Many products in the job shop will have been specially designed and will thus have unique product routes. The length of time of manufacture in a job shop is typically days or weeks rather than hours. Repetitive or batch manufacture is not associated with work undertaken in the job shop.
Jolada: A proprietary system of steel channels on the floor of a vehicle on which pallets may be mounted and moved by jacks.
Johnson's Rule: the primary static job despatching rule.
Journal: In accounting, the journal holds basic financial data and supporting evidence that the financial accounts are based on actual, real transactions. Evidence may include supplier and customer receipts, contracts, business letters etc..

Judgment (or Judgement) Creditor: If a company or person sues another company for debt and obtains judgment in the court for that debt, the company/person is said to be a "judgment creditor".
JUSE: Japanese Union of Scientists and Engineers.
Just in Time: The system of manufacturing employed at the Toyota Motor Company, and devised by the late Taiichi Ohno, a former general manager and MD at Toyota's main plant at Koromo, Tokyo. The system involves the rearrangement of plant and the reorganisation of procedures so that material required for processing arrives exactly at the time it is needed. The overall goals of JIT are to eliminate waste (*) and to synchronise production with the demands of the market. (* The seven categories of waste are said to be: (1) over-production; (2) time spent waiting; (3) time in transportation; (4) processing time itself; (5) time spent in moving the product; (6) the production of non-conforming product; and (7) the creation of stock.) The elements which go to make up JIT, such as cell production, SMED, TPM etc were rechristened "Lean" a few years ago and relaunched as such by the consultancy and conference markets.
