MANAGEMENT OF CHANGE
-
This section aims to support involved parties in leading the Management of Change (MoC) in case of any pragmatic gap between the operation described in the Method Statement and the onsite operation. A risk assessment shall be organized by the person responsible for the concerned activity on site with the involved people.
-
Is there any changes to the pre-defined method ?
DEVIATION
-
Shall we deviate from the initial Method Statement ?
-
JUSTIFICATION
-
Shall new calculations be performed ?
