Ow effective is the joint intelligence committee model?

i would like primary as well as secondary documents.
it is a 4500 essay so that means there is room for alot to talk about.
for assessing how effective it is, i would like to have a brief history on the JIC and how it was created and WHY it was created, including the main characters who were involved. also the context of which it is created.
then i want to go on and talk about the structure of the model it self and what parts it has and what role each play.
then i would like to use an example, of the writers choice to validate whether or not it is effective and to what extent?
