DSS Wisdom
"Briefly stated, to contribute to good decisions information and control
systems should:
1. Produce measures that are complete, objective, and
influenceable by whatever is being measured.
2. Use standards set by decision makers or someone who is
knowledgeable.
3. Have the decision maker or some other credible person act
as the discriminator.
4. Provide information to the decision maker.
5. Provide some sort of motivation for the decision maker to
use the information.
6. Provide data rapidly and at an appropriate time interval.
7. Avoid information overload.
8. Present data in an understandable form and language
(p. 190)."
from Lawler, Edward E, and John Grant Rhode. Information and Control in
Organizations. Pacific Palisades, California: Goodyear Publishing
Company, 1976.

Request for Help - Replacing IFPS
What is a good replacement for models built using IFPS?. The largest
model contains more than 1500 variables (rows) and approximately 80
columns (time periods). Please send me your comments and I will try to
address this question in a future Ask Dan.

Ask Dan!
How many DSS related pages are on the Web?
One means of finding Web sites relevant to DSS is to use a search
engine. Another way is to use a Web index. AltaVista (URL
http://www.altavista.com) is a search engine that provides searches of a
large database. AltaVista provides word count and number of pages found
in a search. Word count is the number of times the word or phrase
appears in documents. In 1997, a search using AltaVista for the phrase
"decision support systems" resulted in a word count of about 10,000,
"decision support" resulted in a word count of about 50,000; and "DSS"
resulted in a word count of more than 51,000. Today, performing a
simple text search using AltaVista for the phrase "decision support
systems" results in a word count of about 70,000, "decision support"
results in a word count of about 330,000, and "DSS" results in a word
count of 441,000. The number of results has increased from 6 to 10
times over the past 3 years.
If one examines the "hits" or documents found, not all of them are
related to decision support in organizations. For example, if one
examines document 1 of about 235,000 matching the query DSS, with the
best matches first, the first Web site identified is "Digitized Sky
Survey", an archive of digitalized photographic plates from telescopes.
However, DSSResources.COM comes first in a search for "decision support
systems". An AltaVista search will identify some useful links, but it
also identifies many false leads. Also, in a basic search you are
limited to the first 200 pages. With some manipulations of the search
string, you can view the first 1000. Also, not all of the links
identified are still active or working.
Another popular search program is Lycos (URL http://www.lycos.com/).
Lycos is one of the best Internet search engines in terms of quantity of
information and relevancy of results. A Lycos search on the phrase
"decision support" found 4,067,140 documents, "decision" found
13,507,000 and "support" found 37,682,956. In 1997, a Lycos search on
the phrase decision support found 291,439 documents with the words
decision (56,604), decisions (34,125) and support (29,295). When one
examines the documents returned the results are again a mix of relevant
and irrelevant Web sites.
One of the initial search programs called Webcrawler (URL
http://www.webcrawler.com/) found fewer matches, and the URLs were not
much more relevant. The first five titles of 1470 from the search for
the phrase "DSS" show the many diverse links that must be sorted: "The
STScI Digitized Sky Survey", "DSS / DirecTV and DirecPC Satellites",
"DSS: What's New", "dss test cards decoder free hack cable DSS TEST
CARDS cartoo...", and "Digital satellite systems (DSS) products and
supplies". The first relevant link is number 6, "ISWorld Decision
Support Systems Research".
Searches using Excite (URL http://www.excite.com), Google (URL
http://www.google.com), and Northern Light (URL
http://www.northernlight.com) show similar results.
Finally, a search of YAHOO! (URL http://www.yahoo.com/) presents a more
organized view of DSS on the WWW. YAHOO! is the pioneer Internet guide
and Web index. It is updated daily and it allows users to both browse
and search subject categories. A search found 79 matches containing
"decision support systems"; 221 matches containing "decision support"
and 136 matches containing "dss". In 1997, a search found 30 matches
containing "decision support systems"; 102 matches containing "decision
support" and 46 matches containing "dss". Some matches are still
irrelevant but in general the links are useful. One main problem for
managers and MIS researchers and practioners is that links need to be
registered with YAHOO so the database is incomplete in the area of
Decision Support. Second, the links are presented in alphabetical order
by YAHOO! category. The categories are very general and often of
limited use.
Despite the problems with using search engines to find Decision Support
Systems information, the Web is an outstanding source of current,
relevant information about DSS software and DSS companies. On the Web
people can visit or "surf" sites quickly and easily. The challenge for
researchers and managers is to find relevant, organized information on
DSS resources available on the Web. I recommend starting with
DSSResources.COM.
Thanks to Alex Power for updating the searches.
