With a narrative style, the reporter does have more flexibility in the structure of the appraisal report and more flexibility in how the information is presented.
But even still, there is a method to the madness of the narrative format, and generally speaking, it follows this format: the first part of the report is the introductory part. The second part is the part where the appraisal problem is identified, discussed, and presented. The data is presented, and then analyses and the conclusions are presented. Finally the addenda is presented, which contains any and all supporting information.
