In Depth Tutorials and Information
Based on the functionalities specification and architecture, a Web-based negotia-
tion process management system is built and utilized for the case study in this
research project. In this prototype system, users can register their own profiles,
build objective hierarchy, declare individual perspectives, generate an argument
structure based on objectives and perspectives, exchange arguments with each
other using Web technology, view related negotiation information collected by the
system, and apply argument evaluation techniques for negotiations.
8.4.2 IWANT Prototype Implementation
A prototype of IWANT is being implemented in Java language, and is being
deployed to support a few software development projects. he prototype is imple-
mented as a Web service on the Apache Web server so that the stakeholders (users)
can access this system via the Internet [Fielding et al. 2006]. To better illustrate the
use of this prototype, three screen snapshots are taken in the prototype and pro-
vided in the figures below. Figure 8.8 is an example of showing the claims related
with one task, which the stakeholders have diferent opinions of. he stakeholders
can add a new claim (e.g., the manager can add his claim following those made by
the engineer and salesperson), view the objective hierarchy (related with the con-
flicting task), or enter the conflict resolution phase. In the claims table, more user-
friendly terms have been implemented, for instance, reason (as data in argument
structure) and proof (as warrant), to improve the user experience.
Figure 8.9 presents the conlict management interface. he stakeholders review
all the relevant claims and then either agree on one claim or use the system to rank
all the claims by a weighted average method. Figure 8.10 shows the ranking result
in an ordered list.
8.4.3 IWANT Applications: Case Studies
his case study is to design an engineering software system for a specific user commu-
nity. Before the experiment, the collaborative negotiation approach was introduced
to the design team with examples and detailed guidelines to make sure the team
has sufficient understanding and abilities to use our approach in the process. For
demonstration purpose, only the case study of applying our approach is presented
(previously case studies without applying this approach were also undertaken).
he research data and analysis of a common design task “Build Communication
Protocol” is also presented.
8.4.3.1 The Negotiation Process
For each design task in this case study, a 6-step procedure was suggested, in which
a combination of our collaborative negotiation process and the common practice
was previously taken by the design team.
