OM 300 Chapter 16 Exam
Questions with 100% Certified
Answers
Sources of variability - Answer-- Poor production processes
- Inadequate Maintenance
- Unknown customer demands
- Incomplete or inaccurate drawings, specifications, or bills of material
Throughput - Answer-time it takes to move an order from receipt to delivery
Manufacturing Cycle Time - Answer-the time between the arrival of raw materials and
the shipping of finished products
Pull system ______ throughput - Answer-increases
How does improving throughput benefit an organization - Answer-1. By pulling materials
in small lots, inventory cushions are removed
- exposes problems and emphasizes continual improvement
2. Manufacturing cycle time is reduced
3. Push systems dump orders on the downstream stations regardless of the need
JIT - Answer-materials arrive where they are needed when they are needed
- powerful for improving operations
JIT helps to - Answer-identify problems
drive out waste
The goals of JIT are to: - Answer-1. reduce variability
2. Lead to cost savings
3. Improve Throughput
JIT requires - Answer-a meaningful buyer-supplier relationship
Supplier partnerships exist when - Answer-a supplier and purchaser work together to
remove waste and drive down costs
4 goals of supplier partnerships - Answer-Removal of unnecessary activities
Removal of in-plant inventory
Removal of in-transit inventory
Improved quality and reliability
, Concerns of Suppliers - Answer-1) diversification
2) scheduling
3) lead time
4) quality
5) lot sizes
Diversification - Answer-ties to only one customer increases risk
Scheduling - Answer-don't believe customers can create a smooth schedule
Lead time - Answer-short lead times mean engineering or specification changes can
create problems
Quality - Answer-limited by capital budgets, processes, or technology
Lot sizes - Answer-small lot sizes may transfer costs to suppliers
Lean layout tactics - Answer-- Build work cells for families of products
- Include a large number operations in a small area
- Minimize distance
- Design little space for inventory
- Improve employee communication
- Use poka-yoke devices
- Build flexible or movable equipment
- Cross-train workers to add flexibility
How distances are being reduced - Answer-- Large lots and production lines are being
replaced by smaller flexible cells
- U-Shaped for shorter paths and improved communication
- Use group tech concepts
How flexibility is increased - Answer-- Cells designed to be rearranged as volume or
designs change
- Applicable in office and production environments
- Facilitates both product and process improvement
Lean Impact on Employees - Answer-- Employees cross-trained for flexibility and
efficiency
- Improved communications facilitate passing important info
- Learn that getting it right the first time is critical
How lean reduces space - Answer-- Inventory must be in very small lots
- Units are always moving because there is no storage
JIT Inventory tactics - Answer--Use a pull system to move inventory
