Ask Dan!

What is PlanningDSS.COM?
by Dan Power

Recently, DSSResources.COM registered a new domain name, PlanningDSS.COM. 
The name summarizes the purpose of the web site -- it is a planning decision 
support system. If you visit the URL, you'll find the following introductory 
message: "Welcome to the Planning Decision Support System. This Web-based 
planning and decision process structuring program has been designed to 
improve contingency course of action (COA) planning decisions and selection 
decisions. The Planning Decision Support System (PDSS) is a prototype built 
using open source web tools. This website,, is still under 
development, so your suggestions and feedback are most welcome. We are 
trying to identify 'alpha' testing opportunities." The HELP menu provides 
links to General, Planner, Decision Maker, Analyst and Observer help. 
Planning DSS is a role-based, multi-user decision support system. It is also 
an integrated decision structuring application with knowledge-driven and 
model-driven decision support subsystems.

This Ask Dan! is a quick synopsis of a 30 year research project, an overview 
of the design for a new web-based decision support application, and a 
request for help and collaboration in extending the project.

PlanningDSS.COM is the most recent incarnation of an idea or a vision for a 
computerized decision support application that I first had in the Fall of 
1975. If nothing else, I have been persistent in trying to make my idea a 
reality.  Certainly the idea has evolved as technologies have changed and as 
I have learned more about DSS design and about decision making behavior.  
But looking back the goals have remained remarkably unchanged. You can read 
a summary of that research covering the period 1975-1984 at Check . 
Also, check the papers I wrote with Professor Gerald Rose when I was a 
student at the University of Iowa (cf., Power and Rose, 1976; Power and 
Rose, 1977).

My first two DECision AID projects were developed using the Hewlett-Packard 
2000 Access system and then the Apple II. "The DECAID idea was that 
questions could be used to build models of the decision making processes. 
These questions could then be programmed using an interactive programming 
language to aid people in making decisions (Power, 1977, p. 28)". In 1986-
87, I had the opportunity to design some applications for the Decision 
Assistant series from Southwestern Publishing Company. These small 
applications were focused on specific decision aiding tools rather than upon 
providing process support and hence helped me see the need for both 
approaches in a more integrated decision support environment.  In the mid-
1990s, I tried to develop a new, more integrated decision aid in Visual 
Basic, but I eventually abandoned that attempt. A number of other false 
starts occurred in continuing my decision aid research. In July 2004, my 
oldest son Alex reviewed the old documentation and a JavaScript application 
we had started and began some PHP/MySQL programming.  That version was 
called DA3000 and the artifact is still on the web at . Alex's work demonstrated the 
feasibility of a new web-based DSS, but showed the need for a more extensive 
and systematic development effort. In Fall 2004, I resolved to make another 
attempt to update and modernize my decision support application using open 
source software and a web platform. Enterprises 
volunteered as a client for the Information Systems Development project 
course at the University of Northern Iowa.  Professor Betsy Hoffman agreed 
to supervise the web DSS project.

In mid-January 2005, a project team of University of Northern Iowa MIS 
majors was assigned to work on my web-based, action planning DSS project.  
To get them started, I provided a concept paper and eventually the team used 
the 1983 version of the decision aid, tried the Decision Assistant 
applications and the JavaScript decision aids.  We agreed on a Scope of Work
for the project.  For three months, the team of Branimir Peitel, Bryce 
Paulson, Luke Thompson and Chun-yi Wu worked on the project.  I brainstormed 
a list of Use cases for the team and they elaborated on them and I gave 
feedback.  Each team member worked on the Use cases for a specific role in 
the system: planner, analyst, decision maker or observer.  The system also 
has an administrator role. The team members were conscientious in showing me 
their Entity-Relationship diagrams for the application database, the 
proposed screen designs, and plans for documentation.  Professor Hoffman met 
regularly with the team and provided direction and encouragement. Their 
diligent work resulted in a prototype that shows what is possible.  A 
complete process has been programmed and some functionality has been 
developed for all five roles.

In a future Ask Dan! column I may summarize the overall concept and/or how 
the system operates, but for now I'll stay focused on a broad overview.  
PlanningDSS.COM may turn into a new business venture, it may be a tool for 
helping DSS students learn about open source software like MySQL and PHP and 
decision process support, and it may serve as an environment for conducting 
research studies.  Both DECision AID and some of the Decision Assistant 
applications were used in prior empirical studies that are described in 
papers I co-authored (Aldag and Power, 1986; Power, Meyeraan, and Aldag, 

Where are we going with this?  During summer 2005, I'll be trying to 
identify resources for further development efforts.  I hope to expand the 
capabilities and do some alpha testing of the system with multiple users in 
a simulated decision making environment.  We are currently checking the 
code, making minor enhancements and preparing a list of additions, 
improvements and new Use cases.

Who has helped with my computerized decision aid projects over the past 30 
years? First, Gerald Rose (Univ. of Iowa), Bobby Brown (Univ. of Iowa) and 
Warren Boe (Univ. of Iowa) supervised and approved my Master's Thesis. My 
friend Ray Aldag (Univ. of Wisconsin) provided support, help and 
encouragement to continue the project when I studied at the University of 
Wisconsin-Madison for my Ph.D. in Business Administration.  At the 
University of Iowa, an undergraduate student William Valliere helped me with 
some programming. At the University of Wisconsin-Madison, Willy Cats-Baril, 
Maureen Sullivan and Scott Conrad helped with programming.  Willy was a 
friend and fellow Ph.D. student in those days. At the University of Northern 
Iowa a number of students have worked on related projects over the years. My 
son, Alex Power, has helped with many DSS projects in the past 6 years. 
Finally, I want to especially thank Betsy Hoffman, Branimir Peitel, Bryce 
Paulson, Luke Thompson and Chun-yi Wu for their help in renewing this 
research stream.  I'm sure I've missed some names on this list, so to all 
those who have helped with my DSS design projects -- Thanks.

If this project sounds interesting and you'd like to get involved in some 
way, send me an email, .  As always your comments and 
feedback are welcomed.
