DTM.1:4.1 - Identify the variant and its continuation

Choose the unit whose continuation is in question. For a working practice, distinguish the method used, a description of it, its competent execution and the participants capable of teaching it. For a device or program, distinguish installed instances from the design and its revisions.

State the criterion by which a later occurrence counts as continuation or a changed variant. A short operational distinction may suffice: “a report prepared with this procedure and checked against independent measurements,” rather than “the same culture.” Where learning changes the method, retain that change for DTM.2.

Then identify the participants and means that enable this continuation: an executor, a provider, an organization allocating time, a communication channel, or an archive. These examples are different relations, not a compulsory list of parts.
