Q1. Explain in brief the origins of Just In Time. Explain the different types of wastes that can be eliminated using JIT Ans. Just in Time (JIT) is a management philosophy aimed at eliminating waste and continuously improving quality. Credit for developing JIT as a management strategy goes to Toyota. Toyota JIT manufacturing started in the aftermath of World War II. Although the history of JIT traces back to Henry Ford who applied Just in Time principles to manage inventory in the Ford Automobile

Just in time (JIT) is a production strategy that strives to improve a business return on investment by reducing in-processinventory and associated carrying costs. Just-in-time production method is also called the Toyota Production System. To meet JIT objectives‚ the process relies on signals or Kanban (看板 Kanban?) between different points in the process‚ which tell production when to make the next part. Kanban are usually ’tickets ’ but can be simple visual signals‚ such as the presence or absence

In this paper‚ we tried to present an overview on the Just In Time practices and how it originated and what it involves from goals and objectives; that would make organizations all over the world apply the concept while aiming at enhancing it’s production‚ minimizing costs and thus generating more revenues. We also tackled Toyota- Car Manufacturing Company as a case study for being one of the very first manufacturers who gave up old traditional manufacturing practices and started implementing JIT

JUST IN TIME LEARNING: Much of the educational materials we receive in our institutions are to prepare us for the future. Many students ask about whether what they are learning will come in handy or when will they use it and teachers reply that just learn it and you can apply it just-in-case when you need it. But when you learn something when it is actually needed and not before time it is known as Just-in-Time learning (JIT). It does not defer the implication of knowledge instead it relies on self
