Qualification: A documented testing that demonstrates with a high degree of assurance that a specific process will meet its pre-determined acceptance criteria. Validation: A documented testing, performed under highly controlled conditions, which demonstrates a process consistently produces a result meeting pre- determined acceptance criteria While qualification is used to provide a high degree of assurance that a process is replicable under anticipated variable ranges, validation is used to describe how a system will perform under highly controlled conditions. Based on the definitions above, it is easy to see how these definitions are interchanged. However, the key difference is determined by whether or not the process under review operates under 'highly controlled' conditions. Answerd By S.K. Karimullah PharmEvo, Karachi, Pakistan

There are a variety of types of validation. These include process design, process qualification, as well as continued process validation.
one is a validation the other is redundancy clue is in the name
A calibration is a process that compares a known (the standard) against an unknown (the customer's device). During the calibration process, the offset between these two devices is quantified and the customer's device is adjusted back into tolerance (if possible). A true calibration usually contains both "as found" and "as left" data. A validation is a detailed process of confirming that the instrument is installed correctly, that it is operating effectively, and that it is performing without error. Because a validation must test all three of these operational parameters, it is broken into three different tests: the installation qualification (IQ), the operational qualification (OQ), and the performance qualification (PQ).
verification: Are we doing the right system? validation : Are we doing the system right?
specificity and selectivity
SDLC has both verification and validation activities where as STLC has only validation activity. Simply STLC is a part of SDLC
Being educated is the act of being taught. So education is teaching.To qualify is to obtain recognition that you can do something. So a qualification is an achievement."After you are educated, to achieve a qualification"
Identification is the act of recognizing objects as a result of remembering them. Qualification is the act of being eligible for something.
Qualification means what expertise you have whereas knowledge when you apply such expertise
Data validation makes sure that the data is clean, correct and meaningful, while data verification ensures that all copies of the data are as good as the original.
The defects detection is the validation process. The defects prevention is a verification process.
AS levels are the first half of A levels, if you stop after the first year you get an AS qualification.
