Answer:
a.Kanban Pull System
Explanation:
Part of a lean manufacturing technique, is the pull system and it is a production or service oriented process used to reduce waste. A pull system is a Lean technique for reducing the waste of any production process. Using a pull system allows you to begin new work only when there is either customer demand for it or goods are required by the next step within the production process. Applying a pull system allows you to start new work only when there is a customer demand for it. This gives you the opportunity to reduce overhead and optimize storage costs.
Kanban is based on a set of principles and practices that are easy to understand. Implementing them is also fairly simple since you do not need to make any serious changes to your existing process. But it is key that you understand the methodology and stick with the core practices if you want to successfully implement a Kanban pull system.
