DTM.1:4.5 - Choose the next modeling question

Use DTM.2 when the uncertainty concerns adoption or further transmission; DTM.3 when participants change through use and thereby change transmission. Use DTM.5 for a conflict between within-group and between-group change, and DTM.7 only when a shared mechanism may be serving a different result.

If the comparison removes the alleged harm, stop the harmful-variant branch. If only the choice among already understood arrangements remains, return to the existing selection and improvement methods. A new dynamic model is not required to preserve an already sufficient conclusion.
