1- What is Quality?
 Quality is a back bone of any organization which help to grow in market for long
term.
 Quality is something which understand customer’s need & can fulfill their
requirements.
 It is something which meets customer’s expectation & increase customer’s
satisfaction.
 It help to increase customer’s faith on the product.
2- Why you want to join as a QA?
 As quality is back bone of organization it will help me as well as organization to
grow.
 As the job is process oriented it will give me the opportunity to do try several things
at the time.
 In a single moment I can apply number of works at a time in which I am good, such
as - the needed documents, test the application, write test plans and test cases,
prepare reports and retest them once again if the need arises & also provide
feedbacks.
 My favorite task would be reducing defects. The more defects I find while working,
the happier I will be.
3- What are the basic Quality tools?
There are 7 basic Quality tools use
 Cause-and-effect diagram (also known as the "fishbone" or Ishikawa diagram)
 Check sheet
 Control chart
 Histogram
 Pareto chart
 Scatter diagram
 Stratification (alternately, flow chart or run chart)
4- Define the basic tools of quality.
Cause-and-effect diagram (also known as the "fishbone" or Ishikawa diagram):-
 It’s the method of problem solving used for identify the root cause of the fault or
problems.
Causes are usually grouped into major categories to identify these sources of variation. The
categories typically include

2.  People: Anyone involved with the process
 Methods: How the process is performed and the specific requirements for doing it,
such as policies, procedures, rules, regulations and laws
 Machines: Any equipment, computers, tools, etc. required to accomplish the job
 Materials: Raw materials, parts, pens, paper, etc. used to produce the final product
 Measurements: Data generated from the process that are used to evaluate its quality
 Environment: The conditions, such as location, time, temperature, and culture in
which the process operates.
Check the fig.1. Below
Check sheet:-
A structured, prepared form for collecting and analyzing data; a generic tool that can be
adapted for a wide variety of purposes. When the information is quantitative, the check sheet
is sometimes called a tally sheet.
Control chart:-
It’s also known as process-behavior charts. It’s the graph used to study how a process changes
over time. Data are plotted in time order. This always has a central line for the average, an upper
line as upper control limit & a lower line for the lower control limit. These line are determined
from historical data.
Histogram:-
A histogram is a graphical representation of the distribution of numerical data. It is an estimate
of the probability distribution of a continuous variable (quantitative variable). It also the most
commonly used graph for showing frequency distributions, or how often each different value in a
set of data occurs.
Pareto chart:-

3. It’s the type of chart that contains both bars & a line graph, where individual’s values are
represented in descending order by bars & the cumulative total is represented by the lines. It’s
the tools which help us to prioritize the major defects from largest to lowest. It works on 80/20
rules, where 80 % of problems may be attributed to 20% of the causes.
Fig 2. Below
Scatter diagram:-
Graphs pairs of numerical data, one variable on each axis, to look for a relationship. It’s a
graph in which the values of two variable are plotted among two axis, the pattern of the
resulting points revealing any correlation present.
Stratification (alternately, flow chart or run chart):-
A technique that separates data gathered from a variety of sources so that patterns can be
seen (some lists replace “stratification” with “flowchart” or “run chart”).
Flow chart: - It’s a type of diagram that represent an algorithm, workflow or process,
showing the steps as boxes of various kinds & their order by connecting them with arrows. This
diagrammatical representation illustrates a solution model to a given problem.
Run chart: - It’s a line graph of data plotted over time. By collecting & charting data over
time, you can find trends or patterns in the process. Because they don’t use control limits. It
can’t tell that process is stable.
6. What are the policy?
 CAP- Corrective Action Policy.
 DAP- Disciplinary Action Policy.
 ZTP- Zero Tolerance Policy.
