2004 - Chemical manufacture

This project took place at an established manufacturing site that was adding an additional process unit to improve quantities of high value products being produced. A workshop was organised for operating staff to learn about the new unit. This included a day to learn start-up and shutdown procedures. Andy suggested that, rather than a class- room lecture, a more interactive approach was possible. Using a graphical task analysis technique (hierarchical task analysis), Andy facilitated the group in developing their own start-up and shutdown procedures. The participants found that, although they knew very little about how to operate the new unit they were able, using their operating experience, process descriptions and drawings, to work out how tasks would be performed. This meant they achieved a much higher level of understanding of the new plant and how it was to be operated.
