Quality control is a process employed to ensure a certain
level of quality in a product or service. It may include whatever actions
a business deems necessary to provide for the control and verification
of certain characteristics of a product or service. The basic goal of quality
control is to ensure that the products, services, or processes provided
meet specific requirements and are dependable, satisfactory, and fiscally
sound.
Essentially, quality control involves the examination of
a product, service, or process for certain minimum levels of quality. The
goal of a quality control team is to identify products or services that
do not meet a company’s specified standards of quality. If a problem is
identified, the job of a quality control team or professional may involve
stopping production temporarily. Depending on the particular service or
product, as well as the type of problem identified, production or implementation
may not cease entirely.
Usually, it is not the job of a quality control team or
professional to correct quality issues. Typically, other individuals are
involved in the process of discovering the cause of quality issues and
fixing them. Once such problems are overcome, the product, service, or
process continues production or implementation as usual.
Quality control can cover not just products, services,
and processes, but also people. Employees are an important part of any
company. If a company has employees that don’t have adequate skills or
training, have trouble understanding directions, or are misinformed, quality
may be severely diminished. When quality control is considered in terms
of human beings, it concerns correctable issues. However, it should not
be confused with human resource issues.
Often, quality control is confused with ASSURANCE . Though
the two are very similar, there are some basic differences. Quality control
is concerned with the product, while quality assurance is process–oriented.
Even with such a clear-cut difference defined, identifying the differences between the two can be hard. Basically, quality control involves evaluating a product, activity, process, or service. By contrast, quality assurance is designed to make sure processes are sufficient to meet objectives. Simply put, quality assurance ensures a product or service is manufactured, implemented, created, or produced in the right way; while quality control evaluates whether or not the end result is satisfactory.
QUALITY CONTROL TOLLS
- This allows the machinist to make required adjustments
to the machinery in order to maintain strict tolerances of the finished
parts. Using quality control tools, the machinist
will observe the readings of the selected parts and adjust the machinery
to maintain the proper finish readings.
- The establishment and monitoring of standards at department level is just as important to quality control as overseeing the overall manufacturing process. Computer technology has made it possible to use automated quality control tools to great effect. Tools of this type are constantly gathering and arranging data in formats that quality control and assurance personnel can evaluate.
