The seven basic quality tools, which are the foundation of
many workplace problem solving approaches, consist of:
1. The tally sheet or check sheet, which quantifies how often something occurs.
2. The histogram presents information from a tally sheet in the form of a bar
chart.
3. The Pareto chart is a special histogram that helps focus attention on the
vital few issues rather than the trivial many.
4. The cause and effect diagram is a brainstorming tool that helps a team
identify potential root causes of a problem.
5. The process flowchart supports the process orientation of ISO 9001 and
similar standards.
6. The scatter diagram allows graphical exploration of the relationship between
two variables, such as a process condition and a critical to quality
measurement.
7. The control chart is a visual control that shows whether a process has
deviated from its target (nominal).
Why Should You Attend
Attendees will learn the applications as well as the mechanics of the seven
basic quality tools. Attendees will learn, for example, not just the mechanics
of a process flowchart but also what they can do with it in the workplace such
as (1) support structure analysis in process FMEA, (2) support value stream
analysis and the related Shingo process map that forces many wastes to become
visible, and (3) support problem solving including root cause analysis. The
concentration diagram meanwhile shows how the tally sheet can go well beyond
just making marks on a sheet to show how often something occurs, a task which
is now generally handled by computers. These seven basic quality tools can do a
lot more than one might assume from their initial appearance.
Areas Covered in the Session
Attendees will learn the function and application of the seven basic quality
tools.
» Check sheet or tally sheet
1. The concentration diagram or "measles chart" is a special
form of this that highlights concentrations of defects or other characteristics
to focus attention on them.
» Pareto Chart
1. This is a special kind of histogram that sorts characteristics (such as
defects) from most important to least important, thus supporting focus on the
vital few versus the trivial many. It can be weighted by the cost (or demerits)
of the defects in case not all are of equal importance.
» Histogram
1. This has many applications including graphical display of a quality
measurement to assess the assumption that it follows a normal or "bell
curve" distribution. Many do not even though this is the textbook
assumption.
» Cause and effect or "fishbone" diagram
1. This supports team problem solving efforts by facilitating the
identification of a problem's potential root causes, and is synergistic with
the Five Whys. Follow the potential root cause to ask "why" until no
further answer can be found, in which case the likely root cause has been
discovered.
2. A designed experiment can test the hypothesis that something is a root
cause. The starting assumption is that the factor (e.g. material or method) is
not a root cause, and the experiment can prove beyond a quantified reasonable
doubt (usually 5%) that it is.
3. The cause and effect diagram also helps identify control factors for
control plans.
» Scatter diagrams
1. The scatter diagram explores graphically the relationship between two
variables x and y, where y might be a critical to quality characteristic.
2. Correlation does not however always mean causation. As an example, the
incidence of head wounds ("quality characteristic") during the First
World War increased after soldiers were issued the Brodie ("tin
Kelly") helmet to replace their uniform caps (input variable, cap versus
helmet) which could lead to the incorrect conclusion that wearing the Brodie
helmet increases your risk of head injury. What really happened was that
soldiers who would have otherwise been killed outright due to lack of a helmet
survived to receive medical treatment. We must therefore always be careful when
we interpret these charts.
» Control Chart
1. Control charts are visual controls that make the status of a process
obvious without the need to read and interpret tables of numbers.
» Process Flow Chart
1. Process flow charts document a process visually and support the process
orientation of ISO 9001 and similar standards.
2.Process flow charts also support structure analysis in failure mode effects
analysis (FMEA) and also value stream analysis.
