So much has been said and written about this topic, that it is almost fruitless to comment. All you need do is google the topic and you will find countless analyses of the benefits of one or another approach, or of each approach. But beware, the writer’s subjective preference will often show, once you do this. For example, Kate Forsyth is probably on the side of plotting, as is James Patterson. And the genre chosen by the author to write in, will determine to a great extent, which approach s/he chooses. Fantasy writers and detective story writers will likely employ plotting as the favoured approach. However, not always. Kate Atkinson writes detective stories, but she is also great with character. She seems to bridge the gap between the two categories in a seamless way.
