Considerations for characterizing domain problems

The nested blocks and guidelines model is a useful template for creating design and evaluation criteria, because it aligns design to need [17]. Characterizing the outermost block of the nested model---the domain problem---is challenging, mainly due to the nature of contemporary inquiries in various domains, which are dynamic and, by definition, difficult to problematize. We offer here our emerging conceptual framework, based on the central question in our research study---what visualization works for whom and in which situation, to consider when characterizing the outermost block, the domain problem, of the nested model [18].
