This chapter addresses a loosely defined group of report types that examine a situation, evaluate the evidence, and render a judgment. Some Rather Fine Distinctions...

They all do roughly the same thing—provide carefully studied opinions and, sometimes, recommendations. There are some subtle differences among some these types.
