Question 1
What are themajor issues facingTom and Masson Miller?
Question 1
Major Problems:
•Increasing the order delivery time from three to four
or five weeks (delay)
•Increasing the number of defective parts

Question 1
Manufacturing Process:
Process Molds Plastic Parts
Volume Low High
Flexibility High Low
Complexity High Low
Customization High Low
Consumer Involvement High Low
Project Mass Production
Question 1
Some Causes:
•Design: this activity takes too long, of course
customer relationship is very important, but idea
clarification can reduce time consuming.
•Purchase row materials: this activity also is time
consume. They can decline the process time by a good
purchase planning.
Question 1
•Mold fabrication: this process itself takes just three to
five days whereas, because of bad planning this
activity may take four weeks.
•Testing: high volume of defective parts shows the
weak testing activity
Some Causes:
Question 2
What are the competitive priorities for custom molds processes and the changing nature of the industry?

Question 2Competitive Priorities of the fabrication process:
•Quality
• Cost
• Lead-time
• Flexibility
Question 2Competitive Priorities of the plastic part:
•Quality
• Cost
• Lead-time
• Flexibility
Question 2Changing the Nature of the Industry:
It needs have changed for both processes in mold fabrication, there is
a need to make very small batches of many different design. in parts
fabrication, there is a need to make large
batches of the same design, longer runs
on the same settings. The demand for
production of molds is slowly declining
while the demand for parts is increasing.
Question 3
What alternatives might be Millers pursue? What key factors should they consider as they evaluate these alternatives?
•Short term to resolve day-to-day
operational problems that would make
immediate performance improvements
•Medium-term decisions require more in-
depth change and it would be more costly
•Long-term strategic operational decisions
which require tight integration with
organization’s objectives
Question 3
Alternatives:
•Improve scheduling to reduce operating and
delivery time
•Using software Programmed
•Improving supplier relationship to reduce the
time of receiving materials
•Designate quality supervisor in charge of mold
fabrication
•More oversight on testing and inspection
•Separate the master machinist from the designer
•Forecast the future orders and needed row materials
Question 3
Short Term Alternatives:
•focus on the supplier relationship
through supply chain management
• methodologies.
•Reorganize plant layout and
processes
•Focus on machinery and invest in
buying the new machinery
Question 3
Medium Term Alternatives:
•Updating the mission and goals of
the company
•Invest in new equipments or even
new firm
•Invest in R&D
