Hi Carlo,
I am also facing difficulties understanding SH events.
As how I see it, whenever a new SH is identified, the SH register has to be updated and so does the SHEM, as this document contains how that particular SH will be engaged in the project.
Likewise, when a SH is no longer relevant, the SH register and the SHEP will be updated. Since the SHEP is being modified and therefore the PMP, a CR is previously required.
Now imagine the following situation: a "leading" SH becomes "supportive" due to illness - because of this illness, she/he cannot actively contribute to the project's success. In this case, the SHEP
is updated but not the SH register, because netither the identification, nor the assesssment information nor the classification have changed (internal/external, impact/influence/power/interest).
Please put this reflection under a BIG question mark. It would be great if someone could contribute here for clarifying these aspects.
Thanks a lot in advance.
BR,
Ildefonso
