Answer: The business continuity strategy is related on how an organization will ensure its recovery and continuity in the face of a disaster or other major incident or business disruption. It covers general decisions applicable to a wide range of types of disasters, major incidents or business disruptions (e.g. use of alternative sites).
The BC plan defines precisely how the organization will manage incidents in the case of a specific disaster or other disruption of business, and how it will recover its critical activities within set deadlines (e.g. BC plan for chemical leakage, fire, etc.).
The BC procedure is a document defining how a specific business continuity activity should be performed (e.g., evacuation procedure).
