 If you think about it, there are some PCs that every designed intervention has. Because of this we can define a fundamental list of PCs that everything you design will //be//. The real questions are //how// and //to what extent// will your interventions exhibit these characteristics. If you think about it, there are some PCs that every designed intervention has.

-None of the questions above are binary - there are no //"yes-or-no"// answers. The answers to all these questions exist on a spectrum: any design can be ranked, at least relative to the reference design, on how much they are better or worse on each of these five PCs.+None of the questions above are binary - there are no //"yes-or-no"// answers.
