One of SCIRT's objectives was to "be proactive and communicate face-to-face where possible". It also aimed to be "approachable". These objectives were regularly measured in community surveys.
Door-knocking was a successful way to meet these objectives and encourage positive contact between SCIRT and the community. It was particularly important in a post-disaster environment where people were coping with many stressors and their ability to process information was impaired. It was also important in communities where written communication was less effective.
