Putting together a training activity for frameworks and looking for content - help please!

Hi all, I am putting together a presentation on frameworks and to try and break up the monotony I want to plan an activity for it. The purpose of this is to give the audience an insight into what I do and how important frameworks are in our business so I wanted to do something along the lines of getting them to read through some documents and find the errors but to also explain the consequences. I thought of something like a legal case study where an error has lead to financial losses.....can anyone suggest or have a resource that can be shared?
