8. DMADV - Q1
1 point possible (graded)
Q8 DMADV refers to Define, Measure, Analyze, Design and
Verify. DMADV is the approach that is followed for those products
and processes that don’t exist and yet to be developed and is also

prioritized to have the most significant effect on the design to
achieve Six Sigma targets. This happens at which phase of the DMADV
approach?

D- The CPU utilization is over 100% on all servers.
What is the systemic root cause (SRC)?
A- Employee A didn’t write a test run for the feature.
B- No training procedure for new employees established.
C- The website was down.
D- The CPU utilization is over 100% on all servers.
16. - 18. 5Whys - Buying a New Table
3 points possible (graded)
Your company produces wooden table and chairs. The legs for
tables and chairs are cut on the same machine. The pieces of
furniture are sold in parts and the customers have to assemble the
parts themselves. One day, a customer complains that the height of
the table he bought and assembled is about 30cm lower than declared
in the product description.
You conduct a 5Why analysis:
1. Why is the height of the table too low? The legs are too
short.
2. Why are the legs too short? They were cut too short.
3. Why were they cut too short? The cutting-machine had the
wrong settings.
4. Why were the settings wrong? They were still adjusted to
cutting legs for chairs.
5. Why were they still adjusted to that? The operator didn’t
change them before the production line switched to
table-legs.
6. Why did he not change them in time? He had an outdated
production schedule.
7. Why did he have an outdated schedule? The weekly update
wasn’t performed as planned.
Please answer the following questions:
What is the problem statement to this 5Why analysis?
A- The height of the table is too low.
B- The legs of the table are too short.
C- The customer complained.
What is the systemic root cause (SRC)?
A- The weekly update wasn’t performed as planned.
B- The legs were cut too short.
C- The operator didn’t change the specifications before the
line switched to table-legs.
What is the occurrence root cause (ORC)?
A- The legs were cut too short.
B- The operator didn’t change the specifications before the
line switched to table-legs.
C- The operator had an outdated production schedule.

Problem 3.4 Part A
1 point possible (graded)
An isotropic alloy contains 5% by volume of a precipitate of
radius 10nm. Assume the primary metal is in a simple cubic
arrangement. The alloy has a Young's modulus E=70GPa and a
Poisson's ratio ν=0.35. If Γ=0.9J/m2 (the energy needed to cut
through the precipitate lattice per unit surface area), and
b=0.25nm, what is the precipitate spacing L in the alloy?
