MAP-01-011 – HFI Technical Guide (STGP 11)According to Burke (DTC030 - 2003), the Team-TA procedure has not yet beenwidely adopted by organisations, with the exception of the US military andaviation communities. Never the less, Team-TA appears to be a very usefulprocedure for eliciting data regarding operating skills and team co-ordination.Although a set procedure for Team-TA does not exist, Burke (DTC030 - 2003)attempted to integrate the existing Team-TA literature into a set of guidelines forconducting a Team-TA.• Advantages• Team-TA goes further than individual task analysis techniques byspecifying the knowledge, skills and abilities required to complete eachtask step.• The output from Team-TA can be used in the development of team trainingprocedures and in team job design.• The Team-TA output specifically states which tasks are team based andwhich tasks are individually performed. This is extremely useful whendesigning new systems.• Team-TA can be used to address team task performance issues.• Team-TA provides a systematic view of the tasks that make up thescenario under analysis.• Team-TA could be used in the identification of team-based errors.• Disadvantages• Team-TA is a hugely time consuming technique to conduct.• SME’s and domain experts are required throughout the procedure. Theacquisition of SME’s can sometimes prove very difficult.• There is no rigid procedure for the Team-TA technique. As a result,reliability is questionable.• Great skill is required on behalf of the analyst in order to elicit the requiredinformation throughout the Team-TA procedure.A3.9.2HTA TeamHTA Team (HTA-T) has been used in a number of team analyses, includingthose for Defence systems. It is an extension of the widely used HTA technique.HTA-T is simple to apply, but may be resource demanding for the largestapplications. It has formed the pre-cursor method for the application of otherHuman Reliability assessment methods, such as TAFEI and SHERPA.May 2006 Page A3-76 Issue 4
