SOP ON PREPARATION, HANDLING, AND REVISION OF VALIDATION MASTER PLAN
The Validation Master Plan is different from a validation procedure (SOP), which describes the specific process for performing validation activities. When plans are written specifically for a single validation project, they are referred to as Validation Plans. Sometimes Validation Master Plans are written to cover specific departmental validation activities or the validation process for a specific type of system (for example, all programmable logic controllers (PLCs) within a manufacturing process). These master plans describe the specific validation process for that group or system type. Master plans are written to assist an organization with validation strategy or to provide control over a specific process.
