Decision Management, predictive analytics
During a panel at Fair Isaac’s Interact conference last week, a banker from Abbey National in the UK suggested that part of the credit crunch was due to the use of the FICO score. Unlike other panelists, who were former Fair Isaac employees, this gentleman was formerly of Experian! So there was perhaps some friendly rivalry, but his point was a good one. He cited an earlier presentation by the founder of Strategic Analytics that touched on the divergence between FICO scores and the probability of default. The panelist’s key point was that some part of the mortgage crisis could be blamed on credit scores, a point that was first raised in the media last fall.
The FICO score is not a probability.
Fair Isaac people describe the FICO score as a ranking of creditworthiness. And banks rely on the FICO score for pricing and qualification for mortgages. The ratio of the loan to value is also critical, but for any two applicants seeking a loan with the same LTV, the one with the better FICO score is more likely to qualify and receive the better price.
Ideally, a bank’s pricing and qualification criteria would accurately reflect the likelihood of default. The mortgage crisis demonstrates that their assessment, expressed with the FICO score, was wrong. Their probabilities were off. Read the rest of this entry »

Ontology, semantic web
I have previously written about the lack of a common upper ontology in the semantic web and commercial software markets (e.g., business rules). For example, the lack of understanding of time limits the intelligence and ease of use of software in business process management (BPM) and complex event processing (CEP). The lack of understanding of money limits the intelligence and utility of business rules management systems (BRMS) in financial services and the capital markets. And, more fundamentally, understanding time and money (among other things, such as location, which includes distance) requires a core understanding of amounts.
The core principle here is that software needs to have a common core of understanding that makes sense to most people and across almost every application. These are the concepts of Pareto’s 80/20 Principle. A concept like building could easily be out, but concepts like money and time (and whatever it takes to really understand money and time) are in. Location, including distance, is in. Luminousity could be out, but probably not if color is in. Charge and current could be out, but not if electricity or magnetism is in. The cutoff is less scientific than practical, but what is in has to be deeply consistent and completely rational (i.e., logically rigorous).[2] Read the rest of this entry »

Business Process Management, Business Rules Management, Decision Management, Learning, business intelligence, predictive analytics

In this article I hope you learn the future of predictive analytics in decision management and how tighter integration between rules and learning are being developed that will adaptively improve diagnostic capabilities, especially in maximizing profitability and detecting adversarial conduct, such as fraud, money laundering and terrorism.
Business Intelligence
Visualizing business performance is obviously important, but improving business performance is even more important. A good view of operations, such as this nice dashboard[1], helps management see the forest (and, with good drill-down, some interesting trees).
With good visualization, management can gain insights into how to improve business processes, but if the view does include a focus on outcomes, improvement in operational decision making will be relatively slow in coming.
Whether or not you use business intelligence software to produce your reports or present dashboards, however, you can improve your operational decision management by applying statistics and other predictive analytic techniques to discover hidden correlations between what you know before a decision and what you learn afterwards to improve your decision making over time.
