1.5.2 Validation and ‘so what’
It's usually not enough to find something; initial conclusions usually require a validation step, a chance to expose them to falsification or corroboration. For example, the conventional validation step for an implementation is an evaluation. The conventional validation step for a novel solution is a demonstration of concept, or a performance test.
Good dissertations are distinguished by ‘asking the next question’, i.e. by not being satisfied with the first result, but investigating its implications and limitations. This investigation is a way of showing the significance and importance of the results.
