Q = 400. Average Inventory = Q/2 = 200. Holding cost/year = $4. Thus,
annual holding cost = $800. Annual set-up cost = 10,000/400 = 25 x $32
= 800. Demand x cost per unit = 10,000 x $150 = 1,500,000. Hence, TC

o Customer needs and feedback. For example, if the team chooses a fast
food chain, they could observe and record defects with preparation and
delivery of the food, cleaning of the restaurant inside and out, including
the rest rooms
o Productivity of the operation and quality of service measured by such
metrics as: wait times per each customer from the time the order is made
until the customer is handed their food, customers served per hour per
total number of employees, number of errors made in products served vs
ordered, friendliness of the staff, and cleanliness of the operation;
including inside the restaurant, outside, in the rest rooms, tables, floors,
waste baskets, etc.
• Identify and develop the problem statement.

• Identify CTQs (critical-to-quality characteristics) the customer
considers to have the most impact on quality.
Execute the measure phase of the Six Sigma DMAIC project including
the following:
• Determine the metrics to measure the process and how it is
performing.
• Identify the key internal processes influencing CTQs and measure the
defects currently generated relative to those processes.

A company is planning for its financing needs and uses the basic fixed-
order-quantity inventory model. Which of the following is the total cost
(TC) of the inventory given an annual demand of 10,000, setup cost of
$32, a holding cost per unit per year of $4, an EOQ of 400 units, and a
cost per unit of inventory of $150?
None of these
$1,501,600
$1,498,200
$499,313
$500,687

A. $1,501,600
Q = 400. Average Inventory = Q/2 = 200. Holding cost/year = $4. Thus,
annual holding cost = $800. Annual set-up cost = 10,000/400 = 25 x
$32 = 800. Demand x cost per unit = 10,000 x $150 = 1,500,000.
Hence, TC = $1,500,000 + 800 + 800 = $1,501,600.
