Just in time in manufacturing - a brief note

Just in time management (in manufacturing) is covered in a few of my taught subjects, e.g. Engineering Management and Strategic Management Accounting. It is useful to highlight the major JIT concepts as an introduction to my students. They can be categorized as (a) JIT philosophy and (b) core JIT techniques and concepts. JIT techniques can further be grouped into 3 categories: (a) in-company JIT, (b) inter-company JIT and (c) supporting mechanisms (Harrison, 1992).

JIT philosophy ---------------------> (JIT techniques & concepts)
(1) Elimiation of waste -------------------->  ( Waste; simplification of systems)

(2) Total quality ------------------------> (Continuous improvement; ownership; integration of effort; prevention; quality control tools)

(3) People preparation -----------------------> (Discipline, flexibility, personal development, autonomy, quality of working life)

Another way to classify JIT techniques is:
JIT1: these techniques are concerned with the preparation of the company in their operations management for competitiveness; JIT1 examples are totaly quality, focus, people preparation, setup reduction, etc.
JIT2: these techniques are concerned with running the facilities in operations management according to JIT philosophy, notably on pursuit of perfect quality and waste elimination; JIT 2 examples include flow scheduling, total people involvement, inventory reduction, visibility, enforceed improvement, and comakership, etc.



These JIT terms and concepts are linked to various Internet  resources for your reference here.
