Question

Calculate the defects per million opportunities (DPMO) given the following: Blake, owner of Blakester's T-shirt Shoppe, keeps track of customer complaints. For each T-shirt sold, there are four possible complaints: T-shirt shrinks, poor quality, design wears off, and doesn't fit right. Each week, Blake calculates the rate of T-shirt "defects" per total T-shirts sold, and then uses this information to determine his company's DPMO. During the past week, his company sold 1200 T-shirts. His company received 22 customer shrinkage complaints, 16 poor quality complaints, 12 design wears off complaints, 8 doesn't fit right complaints. Calculate his firm's DPMO.

Answer 1

Answer:

His firm's DPMO is 12,083

Explanation:

The computation of the DPMO is shown below:

= (Total complaints ÷ total number of defects opportunity) × 1 million

where,

Total complaints = Shrinkage complaints + poor quality complaints + wear off complaints + fitting issue complaints

= 22 + 16 + 12 + 8

= 58 customers defects

And, the total number of defects opportunity would be equal to

= Number of t-shirts sold × number of possible complaints

= 1,200 × 4

= 4,800

Now put these values to the above formula

So, the value would be equal to

= (58 ÷ 4,800) × 1,000,000

=  12,083
