The timing of the CRIOP analysis will be crucial and evaluating this should be given high prioritisation, because;

Recommendations concerning the control room are easier to implement if the analysis is performed early in design. Major changes in control room layout will for instance rarely be made after start-up of the installation, because this has major economic consequences. On the other hand, several questions are not applicable if the analysis is carried out too early, because certain design issues may not be settled.

The output of this section will be:

Identify when the CRIOP analysis should be performed related to the design and operation of a control centre, and establish a CRIOP plan, documenting the time and scope of the different CRIOP analysis. Allocate necessary resources.
