2. Thereare inevitable changes that modify the
process (small or almostimperceptible)
which subsequently affect the product that is
produced or the services it provides.
2. Why is variability important?
It is very important, perhaps more than
what we can imagine, it affects output
variability. Variability is required to modify
the process when you want to get different
results either improve or correct a process
that requires adjustment.
3. 3. What are the types of variability?
There are two types of variability
Identifiable is caused by factors that are
identifiable this variability does not present a statistical
behavior and therefore, are not predictable outputs.
Random: is caused by random factors
(wear, maintenance, measurement equipment, etc.).
4. What are the causes of variability?
Environment. - As this may distort the timing and
quality of the product or service.Change of
operation. - These factors cause variability,
because sometimes the worker must adapt to this
form of work or sometimes just does not
like or you feeluncomfortable. This slows
down production.
4. 5. What are the uses and applications of the
variability?
The uses and applications
that can give variability are
merely productive, because the fact that we
do some kind of change to improve the
production process willthen obtain favorable
results in the product or service.
