How could we summarized the notion of Software Validation? We define Software Validation as a way to obtain the TRUST in the capacity of a company to satisfy the level of quality required. But the complexity of most softwares prevents to be tested in a comprehensive way, the test is therefore a necessity. However, in most cases, the test alone is not sufficient to gain the trust that the software corresponds exactly to the considered use. That is why, in order to establish this TRUST we committed to use a mix of techniques and processes in particular in consulting from Zootechnic, Research and Law prefessionals to prevent from mistakes and present an excellent product really suitable for all.
