DTM.2:4.1 - Name the event to be predicted

Choose an event that answers the work question: first trial, successful execution under named conditions, continued use over an interval, or ability to teach another participant. Distinguish these when one may occur without the next.

Specify who can undergo the event and the opportunity over which its probability or rate is measured. For a weekly adoption count, identify the groups not already using the practice and what counts as a first use during that week. For a transition between two working methods, identify both starting and receiving states.

Return to DTM.1 if “the variant” sometimes means the description and sometimes the performed method. MMP.7 and MMP.16 help model what records actually reveal and choose observations that distinguish competing event definitions.
