Introduction:
Most of the 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.
There are seven basic quality tools
used in organizations. These tools
can provide much information
about problems in the
organization assisting to derive
solutions for the same.
A number of these quality tools
come with a price tag. A brief
training, mostly a self-training, is
sufficient for someone to start
using the tools.
Let's have a look at the seven
basic quality tools in brief.
1. Flow Charts
This is one of the basic quality
tools that can be used for
analyzing a sequence of events.
The tool maps out a sequence of
events that take place sequentially
or in parallel. The flow chart can
be used to understand a complex
process in order to find the
relationships and dependencies
between events.
You can also get a brief idea about
the critical path of the process
and the events involved in the
critical path.
Flow charts can be used for any
field and to illustrate events
involving processes of any
complexity. There are specific
software tools developed for
drawing flow charts, such as MS
Visio.
You will be able to freely download
some of the open source flow
chart tools developed by the open
source community.
2. Histogram
Histogram is used for illustrating
the frequency and the extent in
the context of two variables.
Histogram is a chart with
columns. This represents the
distribution by mean. If the
histogram is normal, the graph
takes the shape of a bell curve.
If it is not normal, it may take
different shapes based on the
condition of the distribution.
Histogram can be used to
measure something against
another thing. Always, it should be
two variables.
Consider the following example:
The following histogram shows
morning attendance of a class.
The .x. axis is the number of
students and the .y. axis the time
of the day.
3. Cause and Effect Diagram
Cause and effect diagrams
(Ishikawa Diagram) are used for
understanding organizational or
business problem causes.
Organizations face problems
everyday and it is required to
understand the causes of these
problems in order to solve them
effectively. Cause and effect
diagrams exercise is usually a
team work.
A brainstorming session is
required in order to come up with
an effective cause and effect
diagram.
All the main components of a
problem area are listed and
possible causes from each area is
listed.
Then, most likely causes of the
problems are identified to carry
out further analysis.
4. Check Sheet
A check sheet can be introduced
as the most basic tool for quality.
A check sheet is basically used for
gathering and organizing data.
When this is done with the help of
software packages such as
Microsoft Excel, you can derive
further analysis graphs and
automate through macros
available.
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.
5. Scatter Diagram
When it comes to the values of
two variables, scatter diagrams
are the best way to present.
Scatter diagrams present the
relationship between two variables
and illustrate the results on a
Cartesian plain.
Then, further analysis, such as
trend analysis can be performed
on the values.
In these diagrams, one variable
denotes one axis and another
variable denotes the other axis.
6. Control Charts
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.
Stability of the process
Predictability of the process
Identification common cause
of variation
Special conditions where the
monitoring party needs to
react
7. Pareto Charts
Pareto charts are used for
identifying a set of priorities. You
can chart any number of issues/
variables related to a specific
concern and record the number of
occurrences.
This way you can figure out the
parameters that have the highest
impact on the specific concern.
This helps you to work on the
propriety issues in order to get
the condition under control.
Conclusion
Above seven basic quality tools
help you to address different
concerns in an organization.
Therefore, use of such tools
should be a basic practice in the
organization in order to enhance
the efficiency.
Trainings on these tools should be
included in the organizational
orientation program, so all the
staff members get to learn these
basic tools.

Quality Improvement Tools

Quality, Quality Management: Meaning and Concepts, Quality characteristics of Products and Services
Definition of 'Quality Management'
The act of overseeing all activities and tasks
needed to maintain a desired level of
excellence. This includes creating and
implementing quality planning and assurance,
as well as quality control and quality
improvement. It is also referred to as total
quality management (TQM).
quality
Quality is important to businesses but can be
quite hard to define. A good definition of
quality is:
“Quality is about meeting the needs and
expectations of customers”
Customers want quality that is appropriate to
the price that they are prepared to pay and the
level of competition in the market.
Key aspects of quality for the customer
include:
Good design – looks and style
Good functionality – it does the job well
Reliable – acceptable level of breakdowns or
failure
Consistency
Durable – lasts as long as it should
Good after sales service
Value for money
‘Value for money’ is especially important,
because in most markets there is room for
products of different overall levels of quality,
and the customer must be satisfied that the
price fairly reflects the quality.
In manufacturing, a measure of excellence or a
state of being free from defects, deficiencies
and significant variations . It is brought about
by strict and consistent commitment to certain
standards that achieve uniformity of a product
in order to satisfy specific customer or user
requirements . ISO 8402-1986 standard defines
quality as "the totality of features and
characteristics of a product or service that
bears its ability to satisfy stated or implied
needs."
Drivers of Quality:
1-Customers.
In a customer-driven organization, quality
is established with a focus on satisfying or
exceeding the requirements, expectations,
needs, and preferences of customers.
Customer-driven quality is a common
culture within many organizations.
2-Products / Services:
A culture of product / service-driven
quality was popular in the early stages of
quality improvement. Conformance to
requirements and zero defect concepts
have roots in producing a product /
service that meets stated or documented
requirements.
In some cases, product / service
requirements originate from customer
requirements, thereby creating a common
link to customer-driven quality, but the
focus of the culture is on the quality of
the product/ service.
If the customer requirements is
accurately stated and designed into the
production / service delivery process,
then as long as the product / service meet
the requirements, the customer should be
satisfied. This approach is common in
supporting the ISO 9001-based quality
management system.
3- Employee Satisfaction:
This concept is that an organization takes
care of employees needs so that they can
be free to worry only about the customer.
Employee satisfaction is a primary
measure of success for this type of
organization.
4- Organizational focus:
Some organizations tend to focus on total
organizational quality while others are
quite successful at using a segmented
approach to implementing quality.
Why quality is important to a growing
business?
Good quality helps determine a firm’s success
in a number of ways:
Customer loyalty – they return, make
repeat purchases and recommend the
product or service to others.
Strong brand reputation for quality
Retailers want to stock the product
As the product is perceived to be better
value for money, it may command a
premium price and will become more price
inelastic
Fewer returns and replacements lead to
reduced costs
Attracting and retaining good staff
Concepts/Elements in Quality Management
Or
Quality Mgmt Plan
Quality Planning
Quality Assurance
Quality Control
Quality planning allows quality to be designed
into the deliverables of the project before the
first task has begun. It is therefore done
during the development phase of the project
life cycle. It may involve identifying standards
or best practices. Design of experiments is one
tool that identifies which variables will have
the most influence on the final quality of a
product.
Quality planning for GIS projects may include
several important aspects, some of which
overlap with those identified for information
technology projects, and some of which are
unique to GIS. For example, functionality is an
important aspect of many IT projects. If you
are customizing an mapping interface, you will
need to address similar questions of
functionality. If, however, you are creating
paper copies of maps for botanists to use as
they collect samples, functionality of how the
map will be used remains important.
Quality assurance is what must be done
during the actual tasks to ensure that the
standards identified during quality planning
are met. It is therefore done during the
implementation phase of the project life cycle.
There are several tools available for a project
manager to assure the quality of products. One
is quality audits , a structured review of
quality with an eye towards improving
performance. Another is benchmarking,
comparing methods or products with others of
recognized quality. Thus, a benchmark is not
something created in the project, but
something recognized by the project and used
for comparison with products or methods in
the project. Sometimes, benchmarks may be
recognized throughout an industry. Other
times, they may be identified uniquely for use
in one particular project.
Quality control is used to improve the quality
of products or methods by focusing on such
outputs as rework decisions, acceptance
decisions, and adjustment of processes. It is
also done during the implementation phase of
the project life cycle. Rework means that a
product does not meet standards, cannot be
provided to the end user as a deliverable, and
must have additional work done to it to bring
it up to standards. Acceptance means that the
product does meet standards and can be
provided to the end user as a deliverable.
Process adjustments are made to corrective
actions taken to the methodology in efforts to
increase acceptance and decrease rework.
Quality Characteristics of Goods and Services
Functionality, how well does it work.
Appearance, how is its look, feel, design, colour, etc
Reliability, how trustworthy is it.
Recovery, how well and how quickly may defects be rectified.
Durability - the total useful life of the product or service.
