2. IMPROVING THE SYSTEM
• To be a successful, business or organization must
balance the needs of this different functional area
around a coherent business vision and strategy.
• The objective of the system is to satisfy the customers.
• Quality system uses the business model with a focus on
customer and includes the dynamics of continual
improvement, change, planning, and renewal. Continual
improvement is necessary for a company to learn to
grow.

3. ISHKAWA’S BASIC SEVEN TOOLS

check
sheets
histograms
Scatter
plots
Control

cause & effect
diagrams
Pareto
analysis
Early stages Final stagesMiddle stage

4. 1- PROCESS MAPS
• A simple process used in city planning department to
take possession of newly built homes .
• Used to Determines which step add value and which
don’t in a effort to simplify the work.
• Also determine whether the work really need to be
done in the first place.

5. 2- CHECK SHEETS
• Are data-gathering tools that can be used in forming
histogram.
• They can be either tabular, computer based or schematic.
• this provides a chart for copier operators to mark each
time a delay occurs in setting up new jobs.

6. 3- HISTOGRAMS
• Histograms are a graphical representation of data, are used
for continues numerical data.
• The histogram is used to determine if the data are normally
distributed.
• It helps to compute the mean, standard deviation, maximum
value and minimum value.

7. 4- SCATTER DIAGRAMS
• Issued to examine the relationship between
variables.
• This relationship are sum times used to
identify indicators variables in organization.
• Scatter plot of the relationship between the
conformance data and prevention and appraisal
quality related to cost in real firm.

8. 5- CONTROL CHARTS
• Are used to determine wither a process will produce a product or service with
contestant measurable property.

9. 6- CAUSE AND EFFECT DIAGRAMS
• Often workers spend too much time focusing
improvement efforts on the problems rather than
on the causes.
• The Ishikawa cause-and-effect or fishbone or
Ishikawa diagram is a good tool to help us to move
to lower levels of abstraction in solving problems.

10. 7- PARETO CHARTS
• Pareto charts are used to identify and prioritize problems to be solved.
• These are actually frequency charts that are aided by the 80/20rule adapted by
Joseph Juran from Vilfredo Pareto, the Italian economist.
• The 80/20 rule states that roughly 80% of the problems are created by 20% of the
cusses

13. OTHER TOOLS
• Spider
Are graphs that present
multiple metrics simultaneously
in tow dimensional plane .
• Dashboards
Looks like a electric meters.
Each of “gauges “ shows a
different metric.
• Balanced scorecard
Are spreadsheets that are communicated
to management on a regular basis.
