You have established a solid committee, asked a strong, clearly defined question, chosen an appropriate methodology, gathered and analysed data and laid out a pretty thorough of academic work so far; you’ve come a long way.

Up until this point in your dissertation, you have been expected to think analytically, now it’s time to think creatively; it’s time to brush the dust off your imagination and take it for a ride. However, you may want to ask yourself, or someone who would know; does this part of the dissertation need to be a separate section or can it just sit inconspicuously among the rest of the work? The conventional (Introduction, methods, results, discussion, conclusion) model might not be the perfect fit for your particular discipline.
You have already gone to great lengths to tell your audience what your findings are, now you have to tell them what they might mean.
