SCM 4367 EXAM 1 REVIEW
Lean, Six Sigma, and TOC can work together - Answer -- All of these work together
because they all aim for continuous improvement in their process and can be
intertwined with each other to improve that process
- Toc informs us where to improve, lean improves on a macro level, six sigma improves
individual processes at a micro level
Thinking People System - Answer -- we must think about processes, productivity,
quality different
- requires creativity, imagination, inventiveness, ingenuity
- system thinking
- abcd influences wxyz
process definition - Answer -collection of activities that transforms inputs into outputs
that offer value to a customer
purpose of a process - Answer -increase:
- value to a customer
- performance (product or service functionality
- speed (decreased lead time)
- quality (consistency, durability, reliability, aesthetics)
- flexibility
decrease cost
importance of customer focus - Answer -in order to create value for a customer, you
have to alter process so that it creates value
historical roots of lean, six sigma, and toc - Answer -- Kiichiro Toyoda
- toyoda family invented lean
- toyoda went to see ford, realized they needed to make changes in their process
- wanted to produce similar results to ford
labor specialization - Answer -craft: low

mass: high
space required - Answer -craft: small
lean: relatively small
mass: very large
tools used - Answer -craft: inexpensive, general purpose, small
lean: flexible, adaptable, small
mass: expensive, specialized, large
process speed - Answer -craft: slow, determined by worker
lean: variable, determined by customer
mass: fast, determined by manager
production lead time - Answer -craft: long
lean: short
mass: relatively long
quality/product reliability - Answer -craft: dependent on worker
lean: consistent
mass: highly variable
improvement - Answer -craft: unpredictable, initiated by worker
lean: continuous, designed by worker
mass: periodic, designed by management
scientific method - Answer --formulate question (defect,etc)
- gather info and define system (process data)
- formulate hypothesis (results,process imprv)
- propose countermeasure (predict)
- implement countermeasure
- evaluate results
value - Answer -output creates value
order winners - Answer -traits that, if provided, will differentiate your product or service
from competition
order qualifiers - Answer -traits that customer experts, customer will not pay for
product/service unless traits are present
mass production mindset - Answer -- eli whitney interchangeable parts
- large variations
- only one model
