Unplanned downtime is placing a greater burden on manufacturers than ever before. Research from Siemens highlights that the cost of unplanned downtime is – in every sector – at least 50% more per hour than it was two years ago. The total losses associated with unplanned downtime are also rising sharply, with the same report estimating that Fortune Global 500 industrial organisations lose almost USD 1.5tn a year through unplanned downtime. This is a 65% rise in two years and constitutes 11% of turnover.
