order of pages when preparing a brief

I suspect that Orden de páginas al elaborar un escrito refers (despite the misleading use of páginas) to the order in which the author of an academic paper (in many disciplines, not just psychology) writes each section of the paper's content.
For example, although the first section is commonly headed 'Abstract', it is usually one of the last sections to be written (because until everything else has been drafted, the author won't know what needs to be given prominence in the Abstract). Likewise, many authors begin by writing the 'meat' of the paper (presentation of the data from which the main conclusions are drawn), and then add the customary layers of 'wrapping' required in academic publications (Introduction, References, Acknowledgements, etc.)

See, for example, "The canonical order" here: https://eigenwelten.com/2010/12/29/how-to-start-writing-a-pa...

Somewhat OT: I used to translate a lot of research papers, and got into the very helpful habit of translating them in an order similar to that used by the authors (many of whom had academic backgrounds). That way, I got to know and understand what the author's 'message' was, and get to grips with the key terminological problems, long before I started to translate the often-times obscure Title, Summary or Abstract.
