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.

Predictive "natural" laws provide some comfort in a complex, volatile and uncertain world. The "laws" simplify and make sense of otherwise complex phenomena. Gordon Moore's Law (1965) has provided that type of comfort to many technologists for almost 50 years. Moore, co-founder of Intel Corporation, made a significant observation about computing. So what is Moore's Law and how has it impacted our thinking about decision support?

Since the early 1950s, much has been written about project management. This literature prescribes generic steps and issues associated with a broad class of projects. In general, a project is a discreet, goal-oriented task or endeavor. A decision support project has a more specific goal of supporting decision making, but there are many ways to do that using a variety of technologies. A decision support project varies in terms of what decision will be supported, what decision makers will use the system, when and how it will be used and what type of decision support will be provided. Also, the technology solution may be poorly understood. Decision support projects are often hard to structure and manage. Moving from an informal exploration of a suggestion for support to a formal project is an important step.

For at least one hundred years, warehousing has referred to the short- or long-term storage of items in a specially designed facility. Originally this general definition described the storage of inventory and other physical items. In the early 1990s, Bill Inmon advocated creating specialized data warehouses for decision support applications. The term data warehousing refers to the process of creating and maintaining a data warehouse.

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.
