HFIDTC/WP1.1.3/10 Version 2/ 31 October 2005 Step 8: Further analysis Once the initial process of transcribing and coding the observational data is complete, further analysis of the data begins. Depending upon the nature of the analysis, observation data is used to inform a number of different HF analyses, such as task analysis, error analysis and communications analysis. Typically, observational data is used to develop a task analysis (e.g. HTA) of the task or scenario under analysis. Step 9: Participant feedback Once the data has been analysed and conclusions have been drawn, the participants involved should be provided with feedback of some sort. This could be in the form of a feedback session or a letter to each participant. The type of feedback used is determined by the analysis team. Example An observational analysis of a fire service training scenario was conducted as part of an analysis of existing C4i activity in civil domains (Baber et al 2004). Three observers observed the fire training service-training scenario, “Hazardous chemical spillage at remote farmhouse”. The three observers sat in on the exercise and recorded the discussion of the participants. The notes from the discussion were then collated into a combined timeline of the incident. This timeline, and the notes taken during the exercise, then formed the basis for the following HF analyses. Hierarchical task analysis Operator sequence diagram Social network analysis Co-ordination demand analysis Comms usage diagram Critical decision method The exercise involved a combination of focus group discussion with paired activity in order to define appropriate courses of action to deal with the specified incident. The class facilitator provided the initial description of an incident, i.e. a report of possible hazardous materials on a remote farm, and then added additional information as the incident unfolded, e.g. reports of casualties, problems with labelling on hazardous materials etc. The exercise was designed to encourage experienced fire-fighters to consider risks arising from hazardous materials and the appropriate courses of action they would need to take, e.g. in terms of protective equipment, incident management, information seeking activities etc. From the data obtained during the observation, an event flowchart was constructed, which acted as the primary input to the analysis techniques used. The event flowchart is presented in Figure 3-10. 29
