It has to be qualifiable and quantifiable. That's what I learned a long time ago when dealing with executives. Make your case understandable and most importantly do a thorough job when it comes to realistic estimations in regard to possible damages. But this means you have to do your homework. No shortcuts and blanket arguments. Understand what it is worth that you try to protect and align the protective measures to these price tags. That's something most executives understand very clearly. Dollars! Hahhaha!
