The goals of both kanban and MRP include
Multiple Choice
determination of capacity required.
reduction of inventories.
smooth rates of output.
explosion of materials required.
larger lot sizes.
The Correct Answer and Explanation is:
Correct Answer: reduction of inventories.
Explanation:
Kanban and Material Requirements Planning (MRP) are two different approaches to managing production and inventory in manufacturing, but they share a common goal: reducing inventory levels while ensuring materials are available when needed.
What is Kanban?
Kanban is a pull-based system originally developed by Toyota. It aims to produce items only as they are needed, thereby minimizing work-in-progress (WIP) and finished goods inventory. A Kanban system uses visual signals (such as cards or bins) to trigger the movement or production of parts. When a part is used in the production line, a signal is sent to replenish that specific part. This avoids overproduction and reduces excess inventory.
What is MRP?
MRP (Material Requirements Planning), on the other hand, is a push-based system that uses forecasts and scheduling to determine what materials are needed and when. It works by breaking down the master production schedule (MPS) into component requirements using a bill of materials (BOM). Although MRP is more data-intensive and complex, its main objective is also to ensure that materials are available for production while keeping inventory levels as low as possible.
Shared Goal: Reduction of Inventories
Despite their different methodologies—Kanban being lean and reactive, and MRP being planned and scheduled—both systems are aimed at reducing inventory. Excess inventory ties up capital, increases storage costs, and raises the risk of obsolescence. By maintaining only the necessary amount of inventory, companies can operate more efficiently and responsively.
The other options in the question are goals or functions more specific to either system or are actually counterproductive:
- Determination of capacity required is more related to Capacity Requirements Planning (CRP).
- Smooth rates of output are a goal of lean or level production, not specifically Kanban or MRP.
- Explosion of materials required is a function of MRP, not a shared goal.
- Larger lot sizes contradict the inventory reduction goal.
Thus, the best shared goal of both Kanban and MRP is the reduction of inventories.
