[Ishiguro] is a planner, patient and meticulous. Before he begins the writing proper, he will spend years in a sort of open-ended conversation with himself, jotting down ideas about tone, setting, point of view, motivation, the ins and outs of the world he is trying to build.
Only once he has drawn up detailed blueprints for the entire novel does he set about the business of composing actual sentences and paragraphs. In this, too, he follows a set of carefully honed procedures.
First, writing very quickly and without pausing to make revisions, heβll draft a chapter in longhand. He then reads it through, dividing the text into numbered sections. On a new sheet of paper he now produces a sort of map of what he has just written, summarizing in short bullet points each of the numbered sections from the draft.
The idea is to understand what the different sections are doing, how they relate to one another and whether they require adjustment or elaboration. Working from this sheet, he then produces a flow chart, which in turn serves as the basis for a second, more painstaking and deliberate draft. When this is finished to his satisfaction he finally types it up. Then he moves on to the next chapter and the process starts again.
