A data management plan is just that, a plan to get all the various actors in your program or center thinking about and committed to data management responsibilities before a project begins. You may need to get data management input from the principal investigator, co-investigators, data collectors, data analysts, information technology (IT) staff, modelers, geographic information systems (GIS) staff, and metadata experts, as each party involved may bring certain expertise related to specific aspects of the plan. If data management details change, your DMP should be updated to reflect those changes.
