Text and Illustration Based Scenario Expressions for Conveying Failure Knowledge
Yotaro HATAMURA, Kensuke Tsuchiya · 2004
Our “Study of Failure” has shown the effects of failure case illustration and text based diagonal scenario expression to successfully convey the essence of failure cases to the reader. A well drawn failure case illustration generates a good image of the failure event in the readers mind, thus succeeds in passing the failure knowledge to the reader. A carefully produced diagonal scenario expression has the same effect. We demonstrated the power of these two fundamentally different representations through an experiment: A failure case illustration alone was shown to a group of people who were asked to define a diagonal scenario expression for the case. The reverse test started from a diagonal scenario expression to reach an illustration that the group had no prior knowledge about. Our tests showed that people can produce a fairly good representation in the other form starting from either an illustration or a diagonal scenario alone.
