videos for business processes

I am facing a problem while teaching OOAD now-a-days on which I need help. Most of the students are from Bachelor of Engineering(IT,E&TC,Mech) and they dont know what are the business processes. What are the systems going on in differnt verticals viz.manufacturing, banking and finance, insurance and many more? I cannot explain modelling, analysis and design of these systems until they know what the systems are. Teaching these systems in the class is time consuming and also going out of scope.

I am looking for videos on this business processes. If anyone knows any links please forward it to me.
