SI VIS is an acronym of a management tool for risk management which stands for
S: Stakeholder: Interessierter, Interessierte Partei
I: Issue: Sache, Sachverhalt
V: Value: Wert
I: Interest: Interesse
S: Situation: Lage in Bezug auf günstige und gefährliche Umstände
and provides an easy and fool-prof pathway to identify risks and opportunities. It works nicely hand-in-hand with SWOT, a complementary tool for the search and identification of risks and opportunities of any kind for any organization.
Stakeholders look at a certain Issue and thus give it a Value. Their Interest in the Situation is related to risk (dangerous circumstances) and opportunity (favorable circumstances).
This method will be applied in Clause 5 "Risk Management Process" / 5.3 "Establishing the context" in Standard ISO 31000.
Unfortunately, the standard IEC/ISO 31010 does neither address SWOT nor SI VIS.
SI VIS did evolve from practical work with the risk management Standards ISO 31000 and 31010.
SI VIS is Latin and essentially means "If you want".
