Migration in progress: |
Define "responsible"
Group which selects, installs, debugs, maintains, updates, and otherwise keeps software functional. Finds alternatives. Secures resources to make work, and otherwise "owns" the problem.
Others can assist and consult and provide "best effort" services. For example, ChemIT will require research groups to confirm the operation of new installations. And research groups may benefit from having ChemIT look over problems the research group is having with their software.

Issues
- Version neglect makes support harder over time, for any of these layers.
- Impact on research when software (1) updates, or (2) upgrades.
