Quality Glossary Definition: Seven tools of quality. Quality pros have many names for these seven basic tools of quality, first emphasized by Kaoru Ishikawa , a professor of engineering at Tokyo University and the father of "quality circles.

Cause-and-effect diagram also called Ishikawa or fishbone diagrams : Identifies many possible causes for an effect or problem and sorts ideas into useful categories. Check sheet : A structured, prepared form for collecting and analyzing data; a generic tool that can be adapted for a wide variety of purposes. Control chart : Graph used to study how a process changes over time.

This samples were made with ConceptDraw DIAGRAM — business process mapping software for flowcharting and used as classic visio alternative because its briefly named "visio for mac" and for windows, this sort of software named the business process management tools.

This flowchart diagram shows a process flow of project management. The diagram that is presented here depicts the project life cycle that is basic for the most of project management methods. Breaking a project into phases allows to track it in the proper manner.

Through separation on phases, the total workflow of a project is divided into some foreseeable components, thus making it easier to follow the project status. A project life cycle commonly includes: initiation, definition, design, development and implementation phases. Distinguished method to show parallel and interdependent processes, as well as project life cycle relationships. A flowchart diagram is often used as visual guide to project. A Pareto Analysis takes into consideration this principle.

Given a set of recurring problems, it is common that a few problems will occur to a greater degree than all the other problems combined. The basic Pareto chart is designed to compare the frequencies of an occurrence, according to problem categories.

In the figure below you can see that the measured data bars are arranged according to categories and plotted against the corresponding frequency. The categories, or bars, are listed in decreasing order. The totals can be noted within bars and are very easy to read and interpret. The chart also uses a line graphic to establish cumulative percentages across the graph. As the category frequency decreases from largest to smallest, cumulative percentage increases to percent.
