Abstract: | Systems whose design is primarily aimed at ensuring efficient, effective and safe working, such as control rooms, have traditionally
been evaluated in terms of criteria that correspond directly to those values: functional correctness, time to complete tasks,
etc. This paper reports on a study of control room working that identified other factors that contributed directly to overall
system safety. These factors included the ability of staff to manage uncertainty, to learn in an exploratory way, to reflect
on their actions, and to engage in problem-solving that has many of the hallmarks of playing puzzles which, in turn, supports
exploratory learning. These factors, while currently difficult to measure or explicitly design for, must be recognized and
valued in design. |
