Hi:

Could someone please define what each of the below term means:

- SPQL
- EFR
- FITS
- IFR

Thank you

How about...

SPQL - Shipped Product Quality Level
EFR - Extrinsic failure rate
IFR - Intrinsic failure rate
FITS - ???? Fun in the sun?

Thank you for your response.

Have a nice day !

best regards,
Quality-1

BTW: I liked the last definition for FITS :)

Obviously, abbreviations and acronyms ought to be defined whenever they are used to avoid confusion or misunderstanding.

FITS = Failures in Time


Failure In Time (FIT) method of specifying component reliability. The FIT rate is defined as the expected number of component failures per 10^9 (ten to the ninth power, or 1,000,000,000) hours. The FIT rate can be converted immediately to the MTBF (Mean Time Between Failures) in hours as MTBF = 10^9/FIT. The Annualized Failure Rate (AFR) can be calculated as AFR = (FIT * 8760)/109.

The advantage of using FIT rates rather than the MTBF metric is that FIT rates are additive. For example, the FIT rate of a current-production M3F-PCIXD-2 interface is 200, the sum of the FIT rate of the fiber transceiver, 125, and the FIT rate of all other component failures, 75. A FIT rate of 200 corresponds to an MTBF of 109/200 = 5M hours, and to an AFR of (200 * 8760)/109 = 0.00175 = 0.175%.

Acronymfinder.com has been very useful in answering questions about acronyms. Unfortunately, acronymfinder only defines the acronym. It does not tell us what the purpose is of the acronym or how the concept may be used in business.

Regards, DirkRight! Once you have the full term, rather than just the acronym, you can do further research on the term to understand its purpose and function. Back in fourth grade, I learned an important lesson:
the Encyclopedia Britannica is only one of many sources of information, not the SOLE SOURCE.
The essence of education is seeking out and using those other sources.

My point in listing the alternate meanings of a group of letters (abbreviation or acronym) was to point out that any acronym is useless without context and collateral knowledge.

My wife, for example, led a sheltered life and had no idea what a SNAFU was before meeting me. Now, to her, I am one!:D

My colleagues have often used the acronym to describe my own brand of
Special High Intensity Training:lmao: when they say I give them a lot of it.
