One of the conclusions of the audit report is: "the business case of the campaign did not demonstrate increased impact for the proposed spending on the air campaign compared to lower-cost alternatives."
...
"The business case did not attempt to quantify the potential impact of increased spending on the air campaign in prompting public action and therefore did not assess the additional value to be derived"
...
and it "lacked a consistent way of measuring impact during the initial period of the campaign, which made it difficult to track the value delivered." and "could not demonstrate that the air campaign resulted in significantly better preparedness"
