Prioritization matrix	JBCS2101316, JAcs2101316	2

3B)

a) Histogram and Pareto chart:

b) Run chart and control chart:

1- Run chart allow the study of observed data for patter over time and control charts gives a study of variation and its source.

2- Control charts can be used to monitor the process and the run charts can be to compare the performance before and after a solution has been implemented.

3- they both use scatter plot.

c) Fishbone Diagram and Prioritization Matrix:
