Examples

There are a few samples that you see on this page which were created in the ConceptDraw DIAGRAM application by using the Seven Basic Tools of Qualityg solution. Some of the solution's capabilities as well as the professional results which you can achieve are all demonstrated here on this page.

All source documents are vector graphic documents which are always available for modifying, reviewing and/or converting to many different formats, such as MS PowerPoint, PDF file, MS Visio, and many other graphic ones from the ConceptDraw Solution Park or ConceptDraw STORE. The Seven Basic Tools of Quality solution is available to all ConceptDraw DIAGRAM users to get installed and used while working in the ConceptDraw DIAGRAM diagramming and drawing software.

Example 1: Cause-and-Effect Diagram

This diagram was created in ConceptDraw DIAGRAM using the Cause-and-Effect Diagram library from the Seven Basic Tools of Quality solution. An experienced user spent 10 minutes creating this sample.

Cause-and-effect diagrams (also known as fishbone diagrams) provide the opportunity to look at the various causes of a specific event. In quality control, they are commonly used to prevent defects in product design, by identifying potential factors that could result in output variance.

Example 2: Frequency Allocation Histogram

This diagram was created in ConceptDraw DIAGRAM using the Histogram library from the Seven Basic Tools of Quality solution. An experienced user spent 10 minutes creating this sample.

A histogram shows the distribution of numerical data. For instance, in this example we can show the most commonly reached wind speeds in a certain area, and this allows you to take an overall look at the data in a relative format.

Example 3: Histogram Example — Age of Presidential Ascension

This diagram was created in ConceptDraw DIAGRAM using the Histogram library from the Seven Basic Tools of Quality solution. An experienced user spent 15 minutes creating this sample.

Plotting the age of US presidents results in a symmetric histogram. Charts of this type make it easy to establish patterns (or the lack thereof), and to work out average results or identify outliers.

Example 4: Pareto Chart — Titanium Investment Casting Defects

This diagram was created in ConceptDraw DIAGRAM using the Pareto Chart library from the Seven Basic Tools of Quality solution. An experienced user spent 15 minutes creating this sample.

A Pareto chart combines elements of a line chart and bar graph, where individual values are shown as bars in descending numerical order, and the line represents the cumulative total of these values. In quality control, a Pareto chart commonly identifies the most common source of defects.

Example 5: Process Flowchart — QA Processes in HSRU

This diagram was created in ConceptDraw DIAGRAM using the Process Flowchart library from the Seven Basic Tools of Quality solution. An experienced user spent 20 minutes creating this sample.

Flow charts are an ideal solution for mapping any form of repeatable action or process within a business. They are versatile enough to show management processes, steps for product design, or data flow within a system.

The Seven Basic Tools of Quality

Every business wants to run at its most efficient equilibrium, with maximum productivity from its workers, cost effective product design and manufacture, and smart strategic decision making regarding managements and HR processes. For this to occur there must be a constant monitoring of business activity, a way of breaking down an organization into its component parts in such a way that they can be analyzed and refined, where any faults, inefficiencies, or redundant processes can be determined and dealt with.

This is the essence of defining quality in the workplace, and the Seven Basic Tools of Quality were conceived as a generic, visual form of tackling these issues. They comprise of seven forms of diagram that are varied enough to be applied to any industry troubleshooting scenario, but simple enough that workers of all types can intuitively understand and implement them.

Despite the title, there are 3 possible options for the last diagram, making 9 in total:

Fishbone diagram

So named because they resemble the bone structure of a fish, fishbone diagrams are also known as Ishikawa diagrams, after their creator and quality control pioneer, Kaoru Ishikawa. Yet another name is a cause-and-effect diagram, and this better explains their purpose — you start with an identified problem, or effect, and work backwards to figure out every causal influence on that effect.

Check sheet

Check sheets are a simple way of making sure that a quality process is followed and standards are followed. They take the form of a grid, where each row is a step that must be checked off in real time as data is gathered.

Control chart

A control sheet records a certain statistic at different times throughout the day, and applies to it a mean data range. If data values fall well outside that range, it could be a sign of an inefficiency or some flaw in a business process.

Histogram

A histogram is used to show the frequency distribution of a specific variable. Visually, they are arranged something like bar charts, but differ in that they don't compare disparate sets of data against each other — instead they take one value, and show its frequency within predefined intervals.

Pareto chart

Pareto charts combines both a bar chart and a line graph, where the bar chart shows individual data values, and a cumulative total represented by the line. In quality control, it is a way of spotting the largest source of defects, complaints, flaws and so on.

Scatter diagram

By plotting against an X and Y axis, a scatter graph can show two variables of a set of data. You can then ascertain the relationship between the variables by how the data points are clustered on the diagram.

Stratification diagram

Stratification is a means of taking data from different sources, and instead of viewing it as a single group, the data is separated by source so as better to identify patterns. To make the data even more representative, the sample size changes according to source.

Flow chart

Flow charts are common throughout business, as a way of representing steps in a process or workflow, shown on the page as boxes containing actions, instructions or decisions.

Run chart

A run chart displays recorded data over a certain time period, where the X axis shows the passage of time, and data points are plotted along the graph as they are observed. The often show some form of measurable manufacturing output, making it possible to quickly identify outliers and shifts in scale and frequency.

These diagram tools have become invaluable to modern business, and with so many cases for their use, it's important that workers of all experience levels can produce clear and effective examples that can be shared across a team and understood at a glance.
