Editorial commentary

A project hold differs from suspension (which is sponsor-initiated) in that it is typically internal to the project's management. Holds may be planned (e.g., during a recruitment freeze) or unplanned (e.g., a critical instrument fails and parts are delayed). Holds are documented in project records and may need to be reported in the next interim report. Long or repeated holds may have downstream effects: revised milestones, schedule slippage, need for an NCE, or impact on cost projections.
