• What are some of the elements that the science
  management plan covers?
• Definition of the Science Team and Scientific
  Roles for the Mission
• Investigation Teams/Guest Investigators/Key
  Projects
• Data rights/Data release/Data centers
• Outreach, conferences, publications,
• When is a science management plan needed for
  LISA?

• How are members of the Investigation Teams
  chosen?
• Will there be individual Investigators in
  addition to the Science Team members?
• If so? How many? How are they funded?
• How will data be distributed? Do
  investigators/science team members have data
  rights?
