Question

Perez Inc. manufactures various types of furniture including couches, tables, and chairs. During April, wood for 1,000 tables entered into the cutting process where wood is cut to design specifications. After the cutting process, the tables entered into assembly, laminating / painting, and packaging processes. Quality control rejected the following tables from the cutting, assembly, laminating/painting, and packaging/shipping processes.

Number of Tables Manufacturing Process Failing Inspection

Cutting    60

Assembly 15

Laminating / Painting 25

Packing / Shipping 5

1. Compute the process yield for cutting. Round to one decimal place.

2. Compute the process yield for assembly. Round to one decimal place.

3. Compute the process yield for laminating/painting. Round to one decimal place. 4. Compute the process yield for packing/shipping. Round to one decimal place.

5. Compute the overall process yield for April. Round to one decimal place.

6. Which processes require improvement?

Answer 1

Process	Input	loss	Out	Process Yield
Cutting	1000	60	940	94%	Question - 1
Assembly	940	15	925	98.40%	Question - 2
Laminate	925	25	900	97.30%	Question - 3
Packing	900	5	895	99.40%	Question - 4
Overall	1000	105	895	89.50%	Question - 5

Process yields are computed as Out put of the process / Input of the process * 100

Cutting = 940/1000 * 100. ...... Assembly = 925/940 * 100 ....... Laminating = 900 / 925 * 100

Note .......... * 100 is optional, check if the answers are needed in percentage terms or not.

Question - 6

Observation of Yield ratios of each process indicates, cutting process needs immediate improvement.
