The plans needs to be continually updated, it is an iterative process. Plans should be reviews and
updated at least every 12 month. If our organization has had a major change we also update the
plans. This could be: We acquired another company or we split off into several companies. We changed
major components of our systems (new backup solution, new IP scheme, …). We had a disaster and we
had a lot of gaps in our plans. A significant part of senior leadership has changed.
