In projects critical for human safety, HINTSW - T & T Systems, acting as independent third party, carries out all the validation and verification (V & V) required by the industry technical standards for the functional safety (IEC 61508, IEC 61511, IEC 50126 / 50128/50129, IEC 62061, etc.); such activities are carried out making use of methodology and techniques of latest generation .
In literature there are many definitions for verification and validation processes, and these definitions often are mutually conflicting, moreover, these processes are almost always presented as procedures performed sequentially; HINTSW - T & T Systems uses the definitions and the implementing rules contained in IEC 61508 and standards based thereon, according to which the V & V are two processes that take place in parallel and covering all phases of system development:
Il processo di Verifica risponde alla domanda:
|We are implementing our project properly ?|
Verification is therefore the process that has the aim of determining whether the products (output) of a given phase of the development life cycle or not meet the requirements for that phase.
Il processo di Validazione risponde alla domanda:
|The result of our project will be correct ?|
Then the validation process is to evaluate products (output) of a given phase of the development life cycle to ensure that these products meet the mission and the needs for which they were made.
