Having your mind already made up AKA tunnel vision is not a good idea. There was still a decision making process that went into your plan, and no one is saying that DODAR (or whatever) has to all happen in the sky. For example: "If the engine fails after V1, we'll fly the plane (A), do the memory stuff and follow this EFP (N) when we've got that done we'll tell ATC what we're doing (C) once above MSA we'll head towards ABCDE, hold if necessary and read the book with a view to returning."
For that particular D, the ODA is done on the ground - but you still need an R in the sky. Is the weather still ok? Has someone crashed and closed the runway? etc.. because if they have then you need to run the whole thing again from the start.
