MDPE.15:4.6 - Obtain a bounded trial and keep its Work separate

Choose trial conditions representative enough for the decision and safe enough for the current change. Identify:

• the tested subject and configuration;
• the performer and observer Systems;
• the trial or evaluation Method;
• obtaining relation to the changed subject;
• relevant environment, audience, partner, instrument, venue, tempo, media, or platform conditions;
• observations, uncertainty, and missing witnesses; and
• protected characteristics and stop conditions.

Change Work and trial Work may overlap—for example, a dancer adjusts a partnering cue during a supervised trial—or occur separately, as when an arrangement is edited and later rehearsed. State their temporal relation separately from any part–whole relation. A trial can be a constituent of larger change Work when its performance contributes to that encompassing work; explain the connection using B.1.5.EW. Overlap or succession alone does not establish it.
