Question

What quality control and improvement tool allows you to view a list of frequency of problems, sorted in descending order?

a)The fishbone diagram.

b)The control sheet.

c) The ABC classification.

d)The process flow diagram

Answer 1

The correct answer is option B- The control sheet.

Explanation:

A) Fishbone diagram- Fishbone diagram is a causal diagram which just shows the various effects with its causes. It has no relation to the frequency of the problem. Therefore it is not the correct answer.

B) Control sheet: Control sheet is a data collection tool in which data is recorded by making marks on the sheet. It is used to quantify a certain type of data. Eg: Quantify defects by type, quantify defects by causes, quatify defects by location etc.

Therefore Control sheet is the tool which can give us a list of frequency of problems, that can be further sorted in descending order.

C) ABC classification: ABC classification is just a tool to calassify the inventory types into A,B and C categories. It does not talk about any defects or problems. Therefore it is not the correct answer.

D) The process flow diagram: Process flow diagram is a diagram used to describe the flow of a certain process in an industry. This tool also does not talk about the defects or problems. Therefore it is not the correct answer.
