Why JIT?

In Kaizen, JIT is a is a collection of concepts and techniques for improving productivity.

JIT is a process aimed at increasing value-added and eliminating waste by providing the environment to perfect and simplify the processes.

Kaizen Mindset

What is JIT?

JIT is a vital component of Lean Manufacturing.

Toyota Production System

Just-in-time manufacturing means producing the necessary items in necessary quantities at the necessary time. It is a philosophy of continuous improvement in which non-value-adding activities (or wastes) are identified and removed.

Putting this concept into practice means a reversal of the traditional thinking process. In conventional production processes, units are transported to the next production stage as soon as they are ready. In JIT, each stage is required to go back to the previous stage to pick up the exact number of units needed.

Benefits of JIT

Reduced operating costs
Greater performance and throughput
Higher quality
Improved delivery
Increased flexibility and innovativeness

Kamban – a Communication Tool in JIT Production System

Being a very important tool for just-in-time production, kamban has become synonymous with the JIT production system.

Kamban, meaning label or signboard, is used as a communication tool in JIT system. A kamban is attached to each box of parts as they go to the assembly line. A worker from the following process goes to collect parts from the previous process leaving a kamban signifying the delivery of a given quantity of specific parts. Having all the parts funneled to the line and used as required, the same kamban is returned back to serve as both a record of work done and an order for new parts. Thus kamban coordinates the inflow of parts and components to the assembly line, minimizing the processes.

Case in Point Canon

The objectives of Canon Production System (CPS) are to manufacture better quality products at lower cost and deliver them faster.

3 Strategies of Market Leaders

The three basic parts of CPS are Quality Assurance (QA), Production Assurance (PA) and Personnel Training (PT).

Production Assurance (PA) System is aimed to achieve just-in-time manufacturing, fast delivery, low cost, and also adopt the "visual control" philosophy. Canon has devised two subsystems to attain these PA goals: Canon's HIT System (equivalent to just-in-time) and Signal System. The HIT System means making parts and products only when needed and only in the quantity needed. Canon uses either HIT cards or signals for this purpose... More

JIT-Style Learning and Training

The best kind of quality oriented learning (and training) is just-in-time-style learning, that is, learning that happens on the job and knowledge which is applied immediately as needed. The sooner you can apply the material you learned, the better you will understand it and the longer it will be retained. Instead of training masses of employees for long periods, in JIT-style training, education is implemented as an ongoing series of short sessions (just a few hours a week) during which employees are taught only what they can apply soon, without suffering information overload.

Innovative e-learning services create new opportunities for such on the job JIT-style learning and training. In particular, this first-ever Ten³ online Business e-Coach provides very effective JIT-style e-learning opportunity which is available free anytime to anybody.
