Greetings to all of my friends who work in the area of computerized decision support. This blog is a way for me to share stories from my encounters related to decision support, to comment on industry events, and to comment on other blogger's comments, especially those of my friends on the Business Intelligence Network. I'll try to state my opinions clearly and provide an old professor's perspective on how computers and information technology are changing the world. Decision making has always been my focus, and it will be in this blog as well. Your comments, feedback and questions are welcomed.

Wisdom is a virtue. Decision support has a short history, but we have learned much about helping people make better decisions with the support of information technology. For many years, a feature called DSS Wisdom was included in my newsletter, DSS News aka Decision Support News. The feature was initiated October 22, 2000 with issue No. 13. The feature stopped after 50 issues, but researchers continue to develop new insights while investigating decision support capabilities and challenges. Innovations in hardware and software continue to expand the reach and range of what is possible and make this field exciting and of continuing relevance. Technology advances have made possible a variety of new tools to assist decision making. Now seems an appropriate time to reflect on the "wisdom" of decision support.

Actions of greedy and naive people caused the crisis. People built and implemented the computerized decision systems that made "bad" loans resulting in high loan default rates. Decision automation facilitated the fast, simplistic decisions and provided an aura of rationality for the "new" instant Web-based lending. Too many people believed the "hype" that automated lending decision making would be both beneficial and effective. Also, the apparent inevitability of competitors automating decisions blinded managers to the risks of adopting cleverly designed and poorly understood software systems. Let's review the facts about what happened.

Data scientist is the "new", "hot", "sexy" and high paying job associated with decision support and analytics. Why? Because data scientists are "the key to realizing the opportunities presented by big data" (Davenport and Patil, 2012). Data scientist is an evolving job category and there are a range of related data science jobs. To better understand the preparation needed for the job(s), it seems appropriate to briefly summarize some job titles, background requirements and job duties. Job duties determine the skills, knowledge and experience needed and hence are the most important topic to analyze. The following is an unscientific, anecdotal review derived from "big data".

Sabermetrics is a specific use of analytics in decision making. It is "the application of statistical analysis to baseball records, especially in order to evaluate and compare the performance of individual players". As originally defined by Bill James in 1980, sabermetrics is "the search for objective knowledge about baseball (cf., sabr.org/sabermetrics)". Sabermetrics has become a popularized example of how facts and statistics can be used to make better decisions.

A specific decision support vision and a well-defined architecture for a new application provides a direction for making design decisions. As technologies evolve computing and decision support architectures change and evolve, but new patterns are not common (cf., Power, 2007). Service oriented and message-based implementations of decision support systems (cf., Natis, 2003) are still not common. The REST/AJAX architectural style is an evolving set of standards for web-based and now smart phone applications. The four traditional DSS architectures, bridge, network, sandwich and tower identified by Sprague and Carlson (1982) continue to provide high-level design direction, but more architectural detail is desirable. REST is an architectural style. A RESTful DSS uses a REST architecture.
