Quality
is defined as the product or services that should be "fit for use and
purpose."
Quality
is all about meeting the needs and expectations of customers concerning
functionality, design, reliability, durability, and price of the product.
What is Assurance?
Assurance
is a positive declaration on a product or service. It is all about the product
which should work well. It provides a guarantee which would work without any
problem according to expectations and requirements.
What is Quality Assurance?

Software
Quality Assurance seems it is all about the evaluation of software based on
functionality, performance, and adaptability; however software quality
assurance goes beyond the quality of the software, it also includes the quality
of the process used to develop, test and release the software.
Software
Quality assurance is all about the Software Development lifecycle that includes
requirements management, software design, coding, testing, and release
management.
Quality
Assurance is the set of activities that defines the procedures and standards to
develop the product.
Quality
Assurance is a systematic way of creating an environment to ensure that the
software product being developed meets the quality requirements. This process
is controlled and determined at the managerial level. It is a preventive
process whose aim is to establish the correct methodology and standard to
provide a quality environment to the product being developed. Quality Assurance
focuses on process standard, projects audit, and procedures for development. QA
is also known as a set of activities designed to evaluate the process by which
products are manufactured.
QA
focused on improving the processes to deliver Quality Products.
What is the Quality Attribute of a software?
The
following six characteristics can define the quality of the software:
1. Functionality
2. Reliability
3. Usability
4. Efficiency
5. Maintainability
6. Portability
What is Quality Control?
Quality
Control popularly abbreviated as QC is a software engineering process used to
ensure quality in a product. It does not deal with the processed used to create
a product. Instead, it examines the quality of the end product and the outcome.
The main aim of Quality Control is to check whether the product meets the
specification and requirement of the customer. If an issue is identified.
What is the difference
between Quality Control and Quality Assurance?
Quality
Control is to examine the product or service and check for the result. Quality
assurance is to explore the processes which led to the end-product.

All
the activities are concerned for QA and QC of any product, not for Software.
In
the case of software
- QA
will act as SQA (Software quality assurance)
- QC
will act as Software Testing

What are the types of
Quality Assurance Function?
There
are five types of Quality Assurance Function.
- Technology
Transfer This function involves getting a project design document as well as trial and error data and its evaluation. The documents are distributed, checked, and approved.
- Validation For the entire system, a validation master plan is prepared. Resource planning for
execution of a validation plan is done.
- Documentation This function
controls the distribution and archiving of documents. Any change in the document is adopting the proper change control procedures.
- Quality
assurance function also involves assuring the quality of products.
- It
also involves quality improvement plans.
