Mismanaged, it is all too easy for an internal issue to become a problem and for a problem to become a crisis. Crises rarely erupt from nowhere. Usually there have been warning signs, or even disclosures, that have been missed, ignored, dismissed or just badly handled.
So what can you do to minimise the risk? Having a good warning system is one way. Do you have systems (formal or otherwise) in place to join the dots between what at first glance might appear small isolated incidents but together point to a larger issue?
