I need an answer for part B and C.

A company produces electric ceiling fans. Currently, the company faces several quality problems in its production. Specifically, the number of defective items is very high (defect rate is high). The top management recognizes the importance of quality in order to remain competitive. In addition, to sustain in a highly competitive market, it is necessary to reduce waste and meet customer expectations, as well as continuous improvement. The senior manager of the company forms a quality team to deal with quality issues and reduce the quality problems faced inside the company. The quality team decides to implement some appropriate quality tools in order to reduce the defective items. The team starts clarifying the problem. Several types of defects that might occur during the production process are identified. Among the identified defect types are improper connections of wires, blade flange under size, poor quality of outer covering, difference between size of upper and lower ribbon, variation in size of canopy, steel ribbon over size, and shorter length of down rod. Then the team used check sheet to gather data and record that which process occurs how many times.

The quality team collected data for one month and the results are shown in table below:

Defect	Frequency
Improper connections of wires	250
Blade flange under size	186
Poor quality of outer covering	232
Difference between size of upper and lower ribbon	354
Variation in size of canopy	435
Steel ribbon over size	94
Shorter length of down rod	268

Answer the following question based on the given data:

a. Determine the major defect types that have the greatest impact on fan quality, as well as the percentage of impact. Show your answer in a graph

b. Explore the potential causes of the defect type with the largest impact identified in part a.

c. Propose a tool for generating ideas that will assist in resolving and eliminating the causes/sub-causes identified in part b. Briefly describe this tool. Please show how to use it to eliminate one cause/sub-cause

The most frequent defect is the 'variation in size of canopy' with 435 complaints. Percentageofimpact=TotalnumberofcomplaintsFrequencyofvariationinsizeofcanopy100=1,819435100
