DMLT Meeting Goals

  • Weekly meeting to keep the DM leadership team coordinated, informed, and in agreement on the vision, priorities, and challenges facing DM construction, including surfacing and resolving issues and ambiguities needing our attention. The goal of this meeting is to provide information and decisions that help each one of us better direct our own (or our team's) activities.

Discussion Items

Guidelines: Propose items in line with the meeting rationale (see above); include as much information in the agenda notes; summarize, don't go into details while on the call; maximize time available for discussion.
