A Lean Journey 
On Fridays I will post a Lean related Quote. Throughout our lifetimes many people touch our lives and leave us with words of wisdom. These can both be a source of new learning and also a point to pause and reflect upon lessons we have learned. Within Lean active learning is an important aspect on this journey because without learning we can not improve.
“Quality control is more than just a state of mind. It requires effective tools.” — McCormack
Most
organizations use quality tools for various purposes related to controlling and
assuring quality. Although there are a good number of quality tools specific to
certain domains, fields, and practices, some of the quality tools can be used
across such domains. These quality tools are quite generic and can be applied
to any condition.

The
Seven Basic Tools of Quality is a designation given to a fixed set of graphical
techniques identified as being most helpful in troubleshooting issues related
to quality. They are called basic because they are suitable for people with
little formal training in statistics and because they can be used to solve the
vast majority of quality-related issues.

little formal training in statistics and because they can be used to solve the
vast majority of quality-related issues.
The tools are:
- Check Sheets – A
generic Tool which can be used for collection and analysis of data. A
structured and prepared form that can be adapted for wide variety of
issues - Control Charts – This is
a graphical technique,which can be used to study the changes to a process
over time - Pareto Chart – This is
another graphical technique, which can be used to identify the
significance of individual factors - Scatter
Chart –
This is used to identify the relation between variables, by plotting pairs
of numerical data, with one variable on each axis. The points will be
falling on a line or a curve, if the variables are related. - Cause and Effect
Diagram (Also
called as Ishikawa Diagram or Fishbone Diagram)
– This can be used to structure the brain Storming Sessions. It is used to
sort ideas into useful categories. Many Possible Causes are identified for
a stated problem and the effect on the problem are identified - Flow Chart
(Stratification Charts) – This tool is used to identify the
patterns within the data collected from multiple sources and clubbed
together. It is used to identify the meaning of the vast data by
identifying patterns. - Histogram – It looks
very much like a bar chart. it is used to identify the frequency of
occurrence of a variable in a set of data.
The
seven basic tools of quality can be used singularly or in tandem to investigate
a process and identify areas for improvement, although they do not all
necessarily need to be used. If a process is simple enough – or the solution
obvious enough – any one may be all that is needed for improvement. They
provide a means for doing so based on facts, not just personal knowledge, which
of course can be tainted or inaccurate. Ishikawa advocated teaching these seven
basic tools to every member of a company as a means to making quality endemic
throughout the organization.
