hey guys this is eric from invensis and
i welcome you to our youtube channel
in today's session we will discuss
quality assurance in detail
so do watch this video till the very end
now before we get started i would like
to address the agenda for today's
session
we will start our session with a brief
introduction to quality assurance
then understand quality assurance
methodology
moving on we will talk about some of the
best practices for quality assurance and
then discuss some methods used for
quality assurance
finally we will conclude the session
with the final topic which is quality
assurance used by various industries
but before that if you like this video
do subscribe to our youtube channel
also to learn more about project
management and its practices check out
invensys learning's project management
certification training on prince2
project management fundamentals po and
msb all of the necessary information cap
is given in the description box below
now starting with our first topic what
is quality assurance
quality assurance or qa is a method of
preventing mistakes and defects in the
manufactured products and assuring that
there are no problems while delivering
products or services to customers
now quality assurance refers to the
administrative and procedural operations
carried out in a quality system to
ensure that a products services or the
activities objectives and goals are met
also ensuring errors are prevented by
systematic measurement comparison to a
standard process monitoring and a
related feedback loop
the quality assurance component focuses
on ensuring that quality criteria are
met
on the other hand quality control is
concerned with the output of the process
next talking about the two principles of
quality assurance
fit for purpose which means the product
should fit the intended purpose and
right first time which means eliminating
all the mistakes are two quality
assurance principles
so now the question here is what does
quality assurance include
quality assurance includes the
management of the quality of raw
materials the different assemblies
products and components the services
related to production
management production and inspection
processes
so the two ideas in building good
products are
first the engineer has to make it work
once while quality assurances task is to
make it work all of the time
now defining what a suitable product or
service quality means has traditionally
been a more difficult process
consequently it has been determined in a
variety of ways
firstly ranging from the subjective
user-based approach which includes the
various weights that an individual
usually attaches to quality
characteristics next to the value-based
approach which finds consumers linking
quality to price and making overall
quality conclusions based on such a
relationship
now talking about the importance of
quality assurance it assists a company
in developing goods and services that
fulfill consumers demands expectations
and standards
it results in a high quality product
that earns customers confidence and
loyalty in addition a quality assurance
program's rules and procedures assist in
avoiding product faults before they
occur
so this was just a brief introduction to
quality assurance
now let us move on to our next topic and
talk about quality assurance methodology
quality assurance methodology structured
cycle known as the pdca cycle also often
known as the deming cycle
now the phases of this cycle are plan do
check act
these stages are done to guarantee that
the organization's procedures are
assessed and improved regularly let's
look into the above qa process steps in
detail
plan first the organization should plan
and create process related objectives
and the process is necessary to achieve
a high quality final result
do second process development and
testing and then also doing
modifications to
processes next check processes are
monitored modified and checked to see if
they achieve the intended goals
then act a quality assurance tester
should take the steps necessary to
enhance the procedures
so this was about quality assurance
methodology now
so let us move on to our next topic and
discuss the best practices for quality
assurance
first is a proper plan
now you must plan every minute detail of
your project if you truly want it to
succeed and you should also include
software testing in the plan
now one of the most important quality
assurance testing best practices is
meticulous preparation
prepare a test plan that details what
will be tested who will be testing it
what resources will be required for the
testing when the deadline will be met
what all the acceptance criteria will be
and next what the current status will be
also be certain that all members of the
qa team are aware of their roles that
they are invited to all important
all-team meetings and that they have
access to all necessary resources
testing schedules should coincide with
project deadlines and quality assurance
professionals should fully understand
project objectives
the second is any procedure that
includes a group of people needs
accountability to succeed
you must develop precise and well-stated
objectives and goals to attain the
responsibility
smart quality assurance goals and
objectives can be implemented
specified measurable achievable relevant
and time-bound objectives are known as
smart goals
they are specific quantifiable
attainable relevant and time-bound goals
these objectives might be professional
that is linked to software testing or
personal that is unrelated to software
testing but equally essential to the
team
the third is employ a multi-directional
testing strategy
one of the most obvious but sometimes
overlooked quality assurance techniques
is to employ a variety of qa types
don't limit your testing to just one or
two categories of testing
you have to perform several testing
methods to find various sorts of issues
quickly
encourage your developers to build
automated unit tests to evaluate the
quality of their code and correct any
issues that come to light during the
testing and then send it to qa to be
tested
after that request the qa team to do the
test and either confirm that the code is
ready to be tested or returned to the
developers for retesting
the fourth is conduct external quality
reviews
getting a second perspective is very
beneficial in software development
you can invite an external specialist to
analyze your product and provide a
technical evaluation as a project
manager product owner team lead or
business owner
they should include a basic summary and
ideas for the team to consider to
enhance their performance
while such a step is primarily intended
for software developers it will greatly
aid qas
after all the goal of both developers
and testers is to provide a high quality
product
however the tone of this quality review
should be taken into account
you must undoubtedly display the report
to the team but make sure it is written
in a polite and constructive tone
the purpose of this evaluation is to
motivate the team to improve their work
habits not to discourage them from
collaborating with you
and the fifth is maintain thorough
documentation
all issues should be recorded and
reported to ensure that the developers
do not miss any issues
documentation is also useful in later
phases of the project
for example if a previously detected and
addressed issue reappears this knowledge
will enable developers to fix it faster
this time because they will know what to
do
additionally documentation helps testers
demonstrate that they carry out their
responsibilities thoroughly
however high-quality documentation is
more essential than mere documentation
if testers ambiguously report issues
developers and project managers will
spend more time attempting to understand
the problem rather than addressing it
testers must use media files such as
screenshots or whatever best shows the
fault to gain clarity
it may be simpler for a developer to
spot the fault just by looking at the
image than reading through a long
confusing description
sixth is maintain a healthy atmosphere
within the team
this is the most obvious and neglected
point among other quality assurance best
practices
fundamentally a pleasant and healthy
environment is essential for project
success retrospectives are another
crucial measure that can help you
maintain team balance
conduct weekly or monthly retrospectives
and allow the team to express their
issues
avoiding this step leads to significant
and unsolvable difficulties so voicing
concerns should be practiced as soon as
they arise finally remember to
appreciate your team members for their
good job
the seventh best practice is to notice
even minor errors
minor errors are still errors
while it may be simpler to dismiss minor
issues experienced developers do not do
so
they realize that a small error might
evolve into a major quality issue in the
future
until you study an issue you don't know
the specific causes behind it
sometimes the error might be an
indication of something more serious
so when these errors appear you can
either repair the issue as quickly as
possible or assign it to the technical
debt
and the eight best practices are to keep
learning and improvising
the quality assurance area like the rest
of the it business is always developing
we all know that technology is evolving
very quickly
the technology techniques and processes
vary and change so the information
gained five years earlier may be of
little use today
so
it is very important to keep learning
and knowing about the latest
technologies and processes
so these were some of the best practices
for quality assurance
now let us move on to our next topic and
talk about the different methods in
which quality assurance is carried out
quality assurance utilizes one of the
following methods
failure testing statistical process
control
total quality management models and
standards
there are many other methods but we will
be primarily talking about these four
methods in today's session
now let us talk about these methods one
by one
first is failure testing which is the
process of repeatedly testing a product
to see if it breaks or fails
this might include testing the product
under heat pressure or vibration if it
is a physical product that has to endure
stress
failure testing for software products
may entail putting the software under
high usage or load situations
the second is statistical process
control which is a methodology created
by walter shewhart at western electric
company and bell telephone laboratories
in the 1920s and 1930s
it is based on using statistical
techniques to control a process or
production method
this methodology can help monitor the
process behavior then discover any
problems and issues in internal systems
and find the necessary solutions for
production issues
next is total quality management which
is a strategy of continuous improvement
that uses quantitative approaches
now to assist product planning and
performance assessments total quality
management depends on facts data and
analysis
the quality of a product is determined
by the quality of the elements that make
it up some of which are sustainable and
well controlled while others are not
total quality management is addressed by
the processes handled using quality
assurance
the product's quality cannot be
guaranteed if the specification does not
represent the genuine quality
requirements for example the operating
environment safety reliability and
maintainability specifications
next are models and standards
iso
17025 is an international standard that
specifies the general testing and
calibration competence standards
there are 15 technical criteria and 10
management needs
these requirements spell out what a
laboratory must accomplish to be
accredited
the management system refers to the
framework of an organization's processes
or activities for transforming resources
into a product or service that fulfills
the organization's goals such as
achieving consumer quality criteria
complying with regulations or meeting
environmental goals
next let us talk about software quality
assurance
software quality assurance is the
process of methodically identifying
trends and taking the steps necessary to
enhance development processes
finding and correcting code errors that
might have unforeseen repercussions
it is possible to repair one item while
working on other features and functions
simultaneously
sqa has become more crucial for
developers to prevent problems before
they occur thereby saving time and money
during development
however even with sqa protocols in place
a software update might damage other
features and result in defects which are
usually referred to as bugs
there have been a variety of sqa
approaches
for example capability maturity model
integration or cmmi is a performance
improvement focused sqa model
cmmi ranks the maturity levels of
various areas within a company and
suggest possibilities for improvement
so these were some of the quality
assurance methods
now let us move on to our next topic and
talk about the quality assurance used by
industries
first is the medical industry in the
medical profession quality assurance is
critical since it helps identify medical
equipment and service standards
hospitals and laboratories use external
agencies to guarantee that equipment
such as x-ray machines diagnostic
radiology and herb meet certain criteria
qa is especially useful during the
development and launch of new
medications and medical equipment
through its members and regulatory
organizations the research quality
association supports and promotes the
quality of research in the life sciences
aerospace industry
product assurance or pa is a phrase that
is commonly used instead of quality
assurance and is one of the three core
project responsibilities along with
project management and engineering
now one aspect of product assurance is
quality assurance
product assurance is especially crucial
since a single failure might have
disastrous effects on human life the
environment a gadget or a mission
it has organizational budgetary and
product development independence which
means it reports solely to the highest
levels of management has its own budget
and does not use labor to assist in
creating a product
product assurance is on par with project
management except it emphasizes the
customer's perspective
software development or software testing
monitoring the software engineering
processes and procedures used to assure
quality is referred to as software
quality assurance
for this many approaches or frameworks
are used such as guaranteeing adherence
to one or more standards such as iso
25010 which replaces iso iec 9126
or process models like cmmi or spice
now enterprise quality management
software is also used to address
challenges like supply chain
disaggregation and assure regulatory
compliance
using contractors or consultants
when adopting new quality practices and
processes consultants and contractors
usually use quality assurance especially
when the necessary skills experience and
resources are not available inside the
business
now for quality assurance quality
management systems auditing and
procedural documentation writing are
frequently used by consultants and
contractors as our cmmi six sigma
measurement systems analysis quality
function deployment failure mode and
effects analysis and advanced product
quality planning
so this was about the quality assurance
used in different industries
and with this we have come to an end of
this video
i hope it was helpful
thank you
