Independence
Shared single points of failure between primary and fallback channels are made visible.
Resilient communication is not created by a second app alone. It requires independent assumptions, reachable contact roles, tested activation and a controlled return to normal operations.
Identity, DNS, email, device and network dependencies of the fallback are compared with the primary system.
A small reachable group can confirm activation independently.
Activation, communication and recovery are tested against realistic disruption.
Open decisions and evidence are transferred back under control.
Shared single points of failure between primary and fallback channels are made visible.
Defined roles may trigger the fallback and document the reason.
Contacts and devices are regularly tested for actual reachability.
Return occurs only after trust review, data reconciliation and approval.
These artefacts are starting points for pilot and operations. They do not replace organisation-specific risk or legal review.
Shared and independent technical and organisational dependencies.
Triggers, authorised roles, first message, audiences and stop conditions.
Time to reachability, missing contacts, channel breaks and actions.
