  1. Identify key decisions that must be made (and justified) prior to CD-1/PDR,
  2. Make progress on (or actually make) those decisions,
  3. Lay out a timeline and process for making each decision, consistent with the post-decision work and internal reviews that will be needed to complete preparations for CD-1/PDR,
  4. Ensure that those timelines and processes are understood and supported by the collaboration, and that we (together) believe we can follow them.

Big questions to answer here:

  • What are we missing?

Note that the L2-level stuff, including the bi-weekly telecon, is all coordination and management; real work is done at L3 and below.

DM scope redefined as raw data coming off the telescopes to well-characterized "reduced data (maps, etc.)." (Used to be "well-characterized maps" but transients...)

  • also responsible for mock data sets to support decisions in other WBSs.

DM transitions to operations in ~2026

  • but there's a data challenge scheduled for 2027, should we change that? (MEM)
  • maybe say DM "begins transition" to ops in 2026.
