DSS Wisdom

Richard Cyert and James March make the following generalizations.  
"Individuals will treat estimates, information, and communication 
generally as active parts of their environment.  They will tend to 
consider the decision for which the information is relevant, the 
probable outcomes of various possible biases in information, and the 
payoff to them of various possible decision results.  They adjust the 
information they transmit in accordance with their perceptions of the 
decision situation." (p. 71)

Ask Dan!

What are the achievements, trends and challenges for Decision Support 
Systems (DSS)?

In late October, Manuel Mora, an Associate Professor in the Department 
of Information Systems, Universidad Autonoma de Aguascalientes 
(, Mexico, asked me to answer a brief e-interview (5 
questions) about the achievements, trends and challenges of 
Decision-making Support Systems (DMSS), including DSS, EIS and Expert 
Systems. In my responses I tried to look broadly at the various types of 
DSS, including Data-driven, Communications-driven, Knowledge-driven, 
Document-driven and Model-driven DSS.  The following are my 
"off-the-cuff" responses to his questions.

1) What are the key achievements from the research and practice of DSS 
in the last 20 years (1981-2001)?

The key achievements seem to be associated primarily with innovative 
products like Expert Choice, GroupSystems, IFPS and PowerPlay. In some 
ways the key achievements have come more from applied research and 
practice than from traditional academic research.  A number of 
Professors have migrated to the commercial realm to pursue their ideas. 
For example, researchers at a number of Universities made substantial 
contributions to the development of Group DSS and their research 
stimulated many studies related to the use of group technologies in 

Vendors have worked to implement DSS products using graphical user 
interfaces and this has increased the accessibility of query and 
reporting tools, decision models and expert system technologies. 
Improved products have not however led to many new empirical studies 
related to how DSS impact decision behavior or decision quality.

2) What are the research issues and practical problems that have yet to 
be resolved in the field?

The research issues related to Decision Support still reads like a long 
shopping list. A few questions standout for me including: How can 
changes in the user interface impact the utility, perceived usefulness 
and effectiveness of a specific category of decision support system? How 
does the metadata available to a user impact the usefulness of a 
data-driven DSS? How does interactive video and voice change the 
dynamics and results of a synchronous meeting where some participants 
are geographically dispersed?

As far as practical problems, they are perhaps fewer in number than 20 
years ago, but more important because of the increased number of DSS 
users and their evolved expectations. Managing and creating large 
decision support databases remains a difficult task. Model management 
and model reuse remain difficult tasks related to building Model-driven 
DSS. Representing knowledge and capturing knowledge from experts in 
useful domains for decision support is certainly not a trivial task.

Despite extensive commentaries, anecdotes and studies, building 
Knowledge-driven DSS seems more like a myterious art than a routinized, 
well-understood development methodology. Finally, communications 
technologies have improved tremendously, but much needs to be done to 
insure that systems are available when needed, perform satisfactorily 
and that needed capabilities for interactive video are provided and 
integrated with other decision support and collaboration tools.

3) What are the 3-5 characteristics for the next generation of DSS for 
all management levels?

There won't be a single next generation for decision support.  Some
characteristics that will appear in decision support systems include 
greater customization, more integration with other information systems, 
integration of interactive voice and video, voice driven user 
interfaces, and more powerful representations including 3-D graphics and 
more realistic, graphical business and process simulations. I'm looking 
forward to "Roller Coaster Tycoon" or "Roller Coaster Designer" like 
decision support simulations.

4) What are the core concepts that are essential for future DSS
architectures ?

>From my perspective the core concept is accessibility, but security 
issues need to be addressed more systematically than they have been in 
recent years. Also the issue of database design and backup is a problem 
in terabyte sized warehouses that will only get worse. The issues 
associated with distributed components (.NET) and the role of 
application service providers (ASPs) will further complicate the design 
of DSS.

5) What are the main trends and challenges in the development of DSS 
from a practical perspective ?

The main trend seems to be vendor consolidation and the main challenge 
remains innovation.  The "older" Business Intelligence and Modeling and 
Analysis vendors seem to be ready for a wave of mergers and other joint 
activities.  Innovation is still possible in this product space and the 
example of Web Decision portals suggests that more innovation is both 
possible and likely.  There is certainly a need for new products in most 
of the decision support categories.

Please send me your comments and I want to extend my good wishes to 
Manuel Mora, Guisseppi Forgionne (UMBC), and Jatinder Gupta (Ball State) 
as they complete their book of contributed articles on DMSS.
