MAP-01-011 – HFI Technical Guide (STGP 11)3. Closeness – The extent to which the position in question is close to theother positions in the group.Each component should be rated between 0 and 1 (0 = Low centrality, 1 = Highcentrality).• Advantages• SNA could be used to highlight the importance of positions within anetwork or group. Conversely, those positions that appear to be of littleimportance to the network could also be classified.• SNA analyses the importance of relationships between operators in aspecified network.• SNA seems to be suited to analysing the importance of relationships incontrol room networks.• SNA is a generic technique that has the potential to be applied in anydomain.• Disadvantages• For complex networks, it would be difficult to conduct a SNA.• The data collection phase involved in a SNA is resource intensive.• SNA would require more training than other team task analysis techniques.• The SNA would be prone to the various flaws associated withobservational analysis, interviews and questionnaires.• SNA is time consuming in its application.A3.9.13Task and Training Requirements Methodology (TTRAM)The Task and Training Requirements Methodology (TTRAM) technique is madeup of a number of techniques that are used to identify team based task trainingrequirements and to evaluate any associated potential training technologies. Thetechnique was developed for the military aviation domain and has shown to beeffective at discriminating tasks that are prone to skill decay, tasks that are criticalto mission success, tasks that require high levels of teamwork (internal &external) and task that require further training intervention. When using theTTRAM technique, that analyst identifies current training and practice gapsthrough interviews with SME’s, and then determines potential training solutionsfor these gaps. In order to identify the current training and practice gaps, a skilldecay analysis and a practice analysis is conducted, which gives the analyst askill decay index score and a practice effectiveness index score. Uponcomparing the two scores, practice and training gaps are identified. Forexample, a task high skill decay index score compared to a low practiceeffectiveness index score would demonstrate a requirement for additional trainingand practice for the task under analysis.May 2006 Page A3-86 Issue 4
