If you don't have the expertise to analyse this system yourself then you need to employ a consultant who does have that expertise. It's too important to get wrong.

On the other hand, if this is an exam question, or homework, then don't expect any help. If you're going to pass exams about this sort of thing then you need to understand it rather than merely copying what someone tells you.
