Propositional networks require an initial CDM analysis as an input. A HTA is also
typically conducted prior to the propositional network analysis. The technique has also
been used in conjunction with a number of other techniques (HTA, observation, coordination
demands analysis, comms usage diagram, social network analysis) in the form
of the event analysis of systemic teamwork (EAST) methodology (Baber et al 2004),
which has been used to analyse C4i activity in a number of domains.
Approximate training and application times
The propositional network methodology requires only minimal training. In a recent HF
methods training session, the training time for the propositional network technique was
approximately one hour. However, the analyst should be competent in the HTA and
CDM procedure in order to conduct the analysis properly. The application time for
propositional networks alone is high, as it involves a content analysis (on CDM outputs)
and also the construction of the propositional networks.
Reliability and validity
No data regarding the reliability and validity of the technique are available. From
previous experience, it is evident that the reliability of the technique may be questionable.
Certainly, different analysts may identify different knowledge objects for the same
scenario (Intra-analyst reliability). Also, the same analyst may identify different
knowledge objects for the same scenario on different occasions (Inter-analyst reliability).
Tools needed
A propositional network analysis can be conducted using pen and paper. However, it is
recommended that during the CDM procedure, an audio recording device is used. When
constructing the propositional network diagrams it is recommended that Microsoft Visio
is used.
