Control chart : Graph used to study how a process changes over time. Comparing current data to historical control limits leads to conclusions about whether the process variation is consistent in control or is unpredictable out of control, affected by special causes of variation.
Histogram : The most commonly used graph for showing frequency distributions, or how often each different value in a set of data occurs. Pareto chart : A bar graph that shows which factors are more significant.
Scatter diagram : Graphs pairs of numerical data, one variable on each axis, to look for a relationship.

Therefore, it is always a good idea to use a software check sheet for information gathering and organizing needs. One can always use a paper-based check sheet when the information gathered is only used for backup or storing purposes other than further processing. When it comes to the values of two variables, scatter diagrams are the best way to present.

Control chart is the best tool for monitoring the performance of a process. These types of charts can be used for monitoring any processes related to function of the organization. These charts allow you to identify the following conditions related to the process that has been monitored.

Trainings on these tools should be included in the organizational orientation program, so all the staff members get to learn these basic tools. Richa Maheshwari. Basic Quality Tools Advertisements. Previous Page. The strategy used to separate data is gathered from various sources.
