Abstract:

Extensions are described for the Systematic Error and Risk Analysis SERA tool. SERA presents an investigator with a series of theoretically based questions and analyses the respondents answers in terms of the source of failure and pre-conditions that led to that failure. Individual investigations using SERA may be saved and returned to at a later time and reports are available for export as text files, which then can be imported into a word processor for formatting. Extensions to SERA included accommodation for the investigation of multiple unsafe acts and porting of the software to a Personal Digital Assistant PDA for effective use in field settings. SERA provides a clear and intuitive interface, context-sensitive help and a foundation for intelligent aiding through an ability to track and represent user actions at the interface. Among the recommendations for future work were reliability and usability testing, designing and implementing an interface to accommodate voice input, where text would otherwise have to be keyed in by hand, and suggestions for intelligent aiding including the possible use of case-based reasoning.
