MGSC 485 Exam 3 Questions with Correct Answers Latest Update 2025/2026
Name the 8 major wastes - Answers defects, over production, waiting, non-utilized resources,
transportation, inventory, motion, excess process (DOWNTIME)
Value Stream Mapping is Based on 2 ideas: - Answers system wide view, visualizing
VSM is - Answers flow kaizen
Product quantity analysis (PQA) - Answers start here to determine if part volumes make the
choice obvious
Product routing analysis (PRA) - Answers use if product-quantity analysis is inconclusive; based
on finding a common equipment and information flow as viewed from customer perspective
Mapping the Value stream to Identify Flow Kaizen Opportunities - Answers 1. Select product
family
2. Draw a current state
3. Draw a future state
4. Develop work plan and implement
The perfect state - Answers completely continuous flow; production lead time so short that one
can make-to-order
What are the steps to identify flow kaizen opportunities? - Answers select product family, draw a
current state, draw future state, develop work plan and implement
Finding Process lead time - Answers Approx. cycle time in seconds or value-added time in
seconds if process lead time longer than cycle time, use longest time if parallel branches.
Sum value-added and lead time at end of flow
VSM Map Design - Answers Customers: upper right
Processes: left to right on bottom
Inventory: between processes (as needed)
Process Cycle Efficiency - Answers Total Process or value added time/Total Production lead
time
Littles Law - Answers I = R x T
, R= Production (in units/day)
T= Flow time (days)
C/O on VSM meaning - Answers Change over time
C/T on VSM meaning - Answers Cycle time
products that go through common steps and consume common resources for most part. -
Answers product family
What is VSM always drawn for? - Answers Product Family
When should product-routing technique be used? - Answers If product-quantity analysis is
inconclusive (e.g., less than an 80:20 ratio between quantity and parts)
When should customer-specific routing technique be used? - Answers If firm makes similar
parts for a variety of customers, each having unique specifications (GE, Sony, and LG product
families)
When should problem-specific routing technique be used? - Answers If specific part type is
experiencing aberrant problems or needs time or quality improvement
Characteristics of a lean value stream system - Answers 1. Produce to takt time
2. Develop continuous flow, or if cannot, use supermarkets to control production
3. Send customer schedule to only one process
4. Distribute production of products evenly
5. Create "initial pull" by withdrawing small, consistent increments
6. Develop ability to make "every part every day"
Take time - Answers available working time/customer demand
When do use super markets? - Answers Control production-where continuous flow does not
extend upstream
What type of system is a supermarket? - Answers Pull system
Alternatives to a Supermarket - Answers FIFO, Sequence Pull
Using only one schedule process in pull system is a ____ process - Answers pacemaker
Pitch - Answers increment of work (take time x pack size)
