Quality and Engineering Services for Complex Systems

Assuring quality, reliability, safety and performance

Product quality assurance of complex systems presents particular difficulties that require a solid expertise to achieve the objective without jeopardizing the time to market and optimizing the cost of the solution. These complex systems are composed of several subsystems, result of the integration of products of different nature, type and origin, which require a depth analysis of the whole system life cycle.


The system manufacturer requires the collaboration of a reliable partner such as Alter Technology that gives support along the whole process with the quality engineering, consultancy and testing services needed.
