The diagram contains four labeled sections arranged horizontally from left to right. On the far left is a box titled “Example direct quotes” containing two text excerpts in quotation marks: “If you want to learn it professionally and look for guidance and you know good Sources in the industry, that’s very difficult, right question mark There’re a few industry associations. There’s a few topics on it, but not much and most of them are very superficial. They don’t really help practitioners get into the real detail of what’s necessary”. attributed to “P5”, and below it another excerpt reading “I don’t see that many ellipses There’s not any kind of design guidance documents that I’m aware of. I’m sure maybe some exist, but, you know, I’ve not seen, you know, a guidance document”. attributed to “P21”. Arrows from these quotes point to a block labeled “Lack of standards and guidelines for C E design” in the next section titled “Code”. A rightward arrow from this block leads to a block labeled “Regulatory and policy gaps” in the next section titled “Subtheme”. Again, a rightward arrow from this block leads to a block labeled “Compatibility barriers” under the last section titled “Theme”. At the bottom right of the diagram is a screenshot-like box shows coded interview excerpts with highlighted text and N Vivo interface details.Illustration of the thematic coding process showing how interview data were categorised into codes, subthemes, and overarching themes.
