P = Publication. Including self-publication here. One good development over recent years has been the realisation authors have to work in co-operation with their publishers so there is more of a team effort. Authors get to speak to their readers more since we have to engage with others. And there has been a massive impact with online publishing, which is a great way of building up your writing CV.
Q = Queries. Ensure everything about your story makes sense. You want to leave your reader with the sense they've had a good read. What you don't want is for your tale to throw up so many queries, it distracts from reading. Make sure that all that needs to be resolved are resolved.
