What is Reliability?
Reliability in the broad sense is the science
aimed at prediction, analyzing, preventing and mitigating
failures over time.
Reliability is quality over time. A reliable, trouble-free
product continues to satisfy customers for a long time.
Reliability in the narrow sense is the
probability that a device will operate successfully for a
specific period of time and under specified conditions when
used in the manner and for the purpose intended.
You cannot purchase the reliability separately and add to your
product for decreasing your expenses in the field (warranty
period).
The reliability assurance or improvement is an integrative
process during development, production, field phases that must
be implemented according to the internal standards for each
designed product.
You should invest the money during design and production for
developing a reliable product and as result save more money
during product warranty period.
Your warranty policy should be based on product reliability
analysis.
Why is it important?
Today's customers both industrial and
consumer, have become much more demanding about product
reliability than they were a few years ago.
Why? Because they know that they can get it!
Who Gains From Good Reliability?
Manufacturer - because his product has additional
customer appeal, through higher quality, faster service, lower
support cost.
The Customer - because the equipment he buys is easier and
less costly to support, has lower down-time - higher
availability.
Reliability-related costs
Reliability-related costs are all those costs
resulting from product field failures or perceived failures
from the time of shipment over the life of the product. They
include warranty costs and the opportunity cost of lost
customers.
Improvements in reliability made by the supplier early in the
equipment life cycle may result in total life cycle costs
decreasing (significant decreasing of Maintenance and
Inventory Costs).

What must be done to have reliable products?
Check your problems and you will understand why you need us.
The following are the major elements required:
• The culture at your company must give its proper importance
to reliability. This may require painful compromises in some
areas.
• Quantitative assessments of Product Reliability must
focusing on the identification and timely elimination of
Design and Processing deficiencies that degrade product
performance and operating life expectancy.
• Communication channels with your customers must be open and
formalized to capture their detailed comments related to
product failures.
• A well-conceived failure database of product field failure
modes supported by failure analysis to root cause is
fundamental to corrective action and improvement.
• Reliability must be designed into products and be included
in all aspects of business. The product development design
engineering team should take the primary responsibility of
your company's product reliability. Formal product development
processes and good project management practices are required.
• Your procurement group must drive supplier quality and
reliability through partnering.
• Manufacturing has to use modern quality control methods to
ensure that components and products are produced according to
specification with negligible variation.
