Appropriate SME’s should then rate the extent to which each teamwork behaviour is
required during the completion of each teamwork task step. This involves presenting the
task step in question and discussing the role of each taxonomy behaviour in the
completion of the task step. An appropriate rating scale should be used e.g. low (1),
medium (2) and high (3).
Step 8: Calculate summary statistics
Once all of the teamwork task steps have been rated according to the teamwork
taxonomy, the final step is to calculate appropriate summary statistics. In its present
usage, a total co-ordination value and mean co-ordination value for each teamwork task
step are calculated. The mean co-ordination is simply an average of the ratings for the
teamwork behaviours for the task step in question. A mean overall co-ordination value
for the entire scenario is also calculated.
Example
The following example is an extract of a CDA analysis of an energy distribution task
(Salmon et al 2004b). The task involved the switching out of three circuits (SGT5 and
SGT1A and 1B) at Barking 275Kv, 132Kv and 33Kv Substations. Circuit SGT5 was
being switched out for the installation of a new transformer for the nearby channel tunnel
rail link and SGT1A and 1B were being switched out for substation maintenance.
Observational data from Barking substation and the NOC control room was used to
conduct a HTA of the switching scenario. Each bottom level task in the HTA was then
defined by the analyst(s) as either taskwork or teamwork. Each teamwork task was then
rated using the CDA taxonomy on a scale of 1 (low) to 3 (high). An extract of the HTA
for the task is presented in Figure 3-11. An extract of the CDA is presented in Table 17.
The overall CDA results are presented in Table 18.
