For example, the claim and the data in one argument were exchanged first before
all other components were exchanged or even generated. If they were not accepted,
the warrant was provided. If still not accepted, the backing was exchanged. If the
combination of claim, data, warrant and backing were not accepted, the qualifier
and rebuttal were the final batch to be exchanged before all the arguments were
evaluated to find out the one which were most preferred.
f. Arguments were evaluated and the one with highest ranking was recommended
Based on the measurements results and calculated preference order, the argument
from the engineering director was most preferred and recommended as the resolution
of the negotiation. In this case study, it took the design team around 2 and half days
(around 21 hours) to complete the entire design process. he average number in the
rounds of generating and exchanging the arguments was 6 before the stakeholders
reached an agreement for each design task. Compared with the 37 hours for the entire
design process and 9 rounds in average for the arguments generation and exchange in a
previous case study where this approach was not applied, it showed both the total time
taken for the design phase and the average number in the rounds of generating and
exchanging the arguments (before an agreement is reached) had been reduced. Also
our analysis showed the commonality of stakeholders' objectives (i.e. the compatibility
of their arguments) has been improved after each round of arguments generation and
exchange. Overall, the decrease in the negotiation time and the improvement in the
commonality of stakeholders' objectives have justified our research approach.
