One of the dilemmas companies face when driving down failures and near misses to ‘zero’ is what to measure. Conventional approaches often fail to support ambitious ‘zero’ performance levels and can discourage the right type of debates and discussions. This guide from the Human Performance (HuP) team explains how biopharma operations can understand and measure performance in the most meaningful way and how to capture risks and enable sustainable learning and improvement through the ‘Family II’ mindset. Piloted by four companies the guide explains how to measure success rates and encourage employee reporting, how to implement such reports, and management the communication around the program to help everyone get closer to the target of zero failures.
