Question

Using the information below construct 3 separate Pareto diagrams as follows:

Construct a Pareto chart for the different operator and machine combinations (without regard to individual defects)

Construct a Pareto chart for the five different days (without regard to defect)

Construct a Pareto chart for the type of defect.

What can you conclude from the 3 diagrams

Operator	Machine	Mon	Tue	Wed	Thu	Fri
A	1	@@@@ ** OO ## +	@@@@@ * OOO #	@@@@@ ***** OOOO ## +	@@@@ * OOO ##	@@@@@ * OOOO ###
	2	@@ * O	@@@ ** OO *	@@@ ***** OO #	@@ * O #	@@ ** O #
B	3	@@ **	@@@@ *	@@@ ***** O #	@@@ * O # +	@@@@ * OO #
	4	@@ * OO +	@@@ * O #	@@@ **** OO #	@@@ + #	@@ + OO #
@ = Strain         * = Scratch          O = Pinholes                            # = Crack         + = Other

Note: Confirmed the data presented is accurate and does not need to be updated.

Answer 1

1. pareto chart for different operators and machines

operators	machine	monday	tuesday	wednesday	thursday	friday	total defects
A	1	11	10	17	10	13	61
A	2	4	6	10	7	8	34
B	3	4	8	11	5	6	35
B	4	6	6	10	5	6	33

from the above table it shows as operator A machine 1 causes more defects

2 pareto data for days

days	defects
monday	25
tuesday	30
wednesday	48
thursday	27
friday	33

from the above table it shows that in wednesday more defects caused.

3. pareto data for different defects

defect name	number of defects
strain	64
strach	38
pinholes	34
crack	20
other	6

from the above table it shows that due to strain more defects caused

from the above three data table we conclude that we have to eradicate defects in Operator A Machine 1 Strain defect ion Wednesday which is cause for more defects,
