My New Year Letter to OpenRules Customers

Dear Customers,

I’m Jacob Feldman, the CTO of OpenRules, Inc. I wanted to reach out to wish you a Happy New Year and thank you for your ongoing support of OpenRules. 2018 was a very successful year for OpenRules. We essentially advanced our decision engine to support a new decision modeling approach. We also received the Business Rules Excellence Award. For those of you who have already experienced the latest OpenRules Release 7.0.0, I hope you are seeing the benefits of the work we did during the last few years to improve the OpenRules robustness, reliability and simplicity of use.

Which changes we may expect in 2019

I was asked by BPM.com to share my thoughts of what to expect in 2019. Digital Decisioning and DMN will continue to play an essential role in BPM. I can see two major trends in this development:

  1. Simplification. Representation of decision logic within business processes will be de-facto standardized using mainly simple DMN concepts such as decision tables and avoiding complex programming concepts. The simplified approaches such as “Goal-Oriented Decision Modeling” supported by OpenRules will continue to prevail in development of decision models incorporated into real-world business process models.
  2. Addressing Complex Decision Optimization Problems. So far, human decision modelers were forced to describe exactly HOW to find a decision by handling all possible combinations of business factors using business rules with multiple exceptions on top of exceptions. More powerful decision engines will allow decision modelers to concentrate on WHAT instead of HOW and will automatically determine multiple feasible decisions and select the optimal decision.

Migrating to OpenRules

OpenRules was introduced to general public as an open source product 15 years ago, and over these years it has become one of the most popular business rules and decision management systems. Every day OpenRules helps customers worldwide handle millions of transactions in real-world production environments for large corporations, government agencies, hospitals, and online businesses – see the list of selected customers. In 2018, along with the Business Rules Excellence Award, we received an overwhelming number of requests from organizations wanting to migrate their existing rules-based systems to OpenRules. This growing interest can be explained by this quote from Forrester Research: “OpenRules have the most-aggressive approaches to business-expert authoring and typically requires less developer support than IBM ODM, FICO Blaze Advisor, and Red Hat Drools“.

So, staring January-2019 we are essentially expanding our technical support and consulting services to help our customers move to OpenRules faster and provide them with superior support. On December 31, 2018 we announced new OpenRules Migration Services – click here to learn how they work.

Model-based Optimal Solutions for Flight Rebooking Challenge

During the closing discussion at the DecisionCAMP-2018, I promoted a new “model-based” approach to decision modeling that contrary to the commonly used “method-based” approach allows a human decision modeler to concentrate on “WHAT” instead of “HOW”. This approach gives more power to decision modelers allowing a decision engine to come up not just with one of many possible decisions but to find the optimal decision. I wanted to demonstrate this power using a more complex business problem and to do it before the end of this year. So, I decided to apply the model-based approach to the problem “Rebooking Passengers from Cancelled Flights” that is the most challengeable problem among multiple DMCommunity.org Challenges.

Model-based Solutions for Advanced Vacation Days Challenge

I provided two solutions for DMCommunity.org Challenge “Vacation Days Advanced”. So far, all decision models submitted as solutions for the old Jan-2016 Challenge and the new challenge were “method-based” meaning they describe exactly how to assign extra days while avoiding possible conflicts. I tried to apply a new “model-based” approach that concentrates on “what” instead of “how” and finds not just one of many possible solutions but the optimal one.  The first decision model consists of clearly separated two parts: 1) Business Part presented in Excel decision tables; 2) Technical Part presented in Java using the JSR-331 standard. The second decision model is an attempt to present both parts completely in DMN-like decision tables using Excel only (the supporting Java code is hidden in new Excel templates). You may analyze both solutions here. I’d appreciate comments and suggestions for improvement.

“Model-based” vs. “Method-based” Approaches to Decision Modeling

In Aug-2018 Prof. Robert Fourer gave a tutorial “Model-based Optimization“, in which he compares two essentially different approaches to modeling optimization problem: “model-based” vs. “method-based”. He is using a relatively complex “Balanced Assignment” problem to demonstrate his points. While Fourer’s tutorial deals with optimization, I believe the same arguments are directly related to Decision Modeling that so far mainly remains method-based. During DecisionCAMP-2018 we had interesting (and sometimes hot) discussions about these two approaches and in my closing remarks I described the major differences between them as follows: Continue reading →

Notes from DecisionCAMP-2018

This year DecisionCAMP was held in Luxembourg Sep 17-19 as a part of the Logic for AI Summit. It became an important event that attracted experts and practitioners in the business decision management from 14 countries. We had 54 official registrations and sometimes even more people were present in the auditorium. The representatives from almost all major BR&DM vendors and many well-known experts attended the event. As the chair of the event, I wrote the Notes from DecisionCAMP-2018 published at the DMCommunity.org blog.

OpenRules customer selected as worldwide Awards Finalist

A major California bank, facing looming regulatory deadlines, needed to develop a highly dynamic web application to support the bank’s complex customer account management processes. The integrated use of OpenRules’ s rule and rendering engines became the foundation for the successful and quick implementation. OpenRules nominated this real-world application to the first annual Business Rules Excellence Awards (BREA).  This success story was selected as a worldwide Finalist in the 2018 Business Rules Excellence Awards. This is a significant achievement for the Bank and OpenRules. The announcement of winning entries will take place on October 16.

OpenRules Presentations at DecisionCAMP and LuxLogAI-2018

OpenRules was well presented at the major technical business decision management event DecisionCAMP-2018. Here are the presentations directly related to OpenRules:

I also published a paper “Building and Analyzing Goal-Oriented Decision Models” at the Proceedings of the RuleML+RR 2018 Challenge – it explains our goal-oriented approach to decision modeling using a Credit Card Application decision model. In my closing notes I tried to demonstrate how a smarter decision engine can simplify decision modeling using concrete examples from DMCommunity.org challenges. After considering different decision modeling approaches, we will add these capabilities to standard OpenRules features.

DMCommunity Challenge July-2018 “Zoo, Buses, and Kids”

The July’s challenge “Zoo, Buses, and Kids” deals with a very simple optimization problem:
“300 kids need to travel to the London zoo. The school may rent 40 seats and 30 seats buses for 500£ and 400£. How many buses of each to minimize cost?”
Naturally, a constraint solver nicely and easily solves this and more complex constraint satisfaction problems as shown in Philippe Laborie’s solution. When today I saw  a pure SQL solution provided by Damir Sudarevic, I thought that it’s time to model this problem as a business decision model. It would not be as compact as provided solutions, but it should be oriented to business users.  Continue reading →

Decision Automation and Explanations

Prof. Gene Freuder wrote a position paper “Complete Explanations” for The Second Workshop on Progress Towards the Holy Grail that will be held on Aug 27, 2018 during CP 2018 in Lille, France. Gene writes: “As AI becomes more ubiquitous there is a renewed interest in computers being able to provide explanations, and the European GPDR provides special impetus.” Geen’s paper concentrates on constraint satisfaction problems (CSPs), but, as I’d shown in my 2016 paper, we may consider a decision model as a CSP, and everything Gene is talking about directly applies to business decision modeling.

Goal-Oriented Decision Modeling with OpenRules-7

The major Release 7.0.0 is making OpenRules even more user-friendly without losing any of the sophistication of already proven decision modeling technology. Our customers don’t have anymore to define an execution sequence of their decision tables in special tables of the type “Decision” – these tables can be automatically generated. Now it is sufficient for a human decision modeler to define only Glossary and Decision Tables that specify business logic for all included goals and subgoals. Then for any selected business goal, OpenRules Engine will execute all related decision tables in an automatically calculated order to determine the goal’s value. You may watch this short video that uses simple examples to explain the goal-oriented approach to decision modeling supported by OpenRules-7. Continue reading →

Keep DMN Simple

People who started decision modeling standardization years ago were all agreed that the DMN standard is supposed to be oriented to subject matter experts, should be simple, friendly enough while powerful to cover the common denominator in operational decision modeling. It was a good start for DMN in 2013 and an enthusiastic acceptance since then. However, today DMN is full of complex, programmer-oriented features which seem to get even more complex in new releases. There are plenty examples of unnecessary complexity being proudly promoted for their “elegance”.  Here are a few examples to compare. Continue reading →

Old Decision Model “Credit Card Application” Implemented with New OpenRules-7

The latest June-2018 DMCommunity Challenge”Credit Card Application” gives me a good chance to demonstrate the new upcoming OpenRules Release 7.0.0. I remember that Nick Broom was one of the first who published a real-world decision model right after the DMN introduction. I also remember that at the same day I implemented and published  Nick’s model using only Excel and OpenRules  available at that time (it was release 6.2.6). It would be interesting to compare this old implementation with a new one below that takes advantages of new OpenRules-7. Continue reading →

DMCommunity Challenge April-2018 “Up-Selling Rules”

In this post we will provide a response to the DMCommunity.org Apr-2018 Challenge “Up-Selling Rules“  that deals with two decision tables: 1) up-selling rules that offer new products to a customer based on the customer profile and the products which the customer already has; 2) customer profiling rules. We will use for the first time the latest OpenRules version (not released yet to public) that removes a need for ordering of multiple decision tables.  Continue reading →

Decision Management and Semantic Reasoning

Considering the upcoming conferences, I was asked by Harold Boley to write about a possible integration of Semantic Reasoning and Business Decision Management. Today I posted an article at the RuleML Blog and decided to reproduce it here as well but in a bit more friendly format.
On September-2018 DecisionCAMP and RuleML+RR will be co-located again for the third time during the LuxLogAI-2018 summit in Luxembourg. These two events represent different but closely related fields of the knowledge representation movement: Business Rules & Decisions Management and Semantic Reasoning. In this post I want to talk about relationships between these two fields and events.

Happy 15th Birthday, OpenRules!

Today is exactly 15 years since OpenRules, Inc. was incorporated on Feb. 24, 2003. It’s a quite serious milestone, so I decided to write a few words for this occasion. A year ago, I described a brief history of our company and key factors that made it successful. 2018 was an extremely successful year for OpenRules as well: we improved the product and many major corporations became our new customers. But in this post I want to look to the future and to share some of our upcoming and long term plans. Continue reading →

Introducing DMN to Business Analysts in 15 Minutes

Last year BBC-2017 organizers gave me 20 minutes to introduce DMN to business analysts at the “Technology Theater”, an open space in the Expo hall. Based on the positive feedback from people who attended my presentation, I decided to share it with more people.  You may look at my slides in the PDF format. Below I will describe an example I believe  is very useful to introduce major DMN concepts in 15 minutes. Continue reading →

Decision Modeling: LEGO Style

Recently I helped one of our larger customers to build a set of their business decision models. At the end I said that now they can continue to assemble new decision models themselves. Then one of their business analysts said that our decision modeling approach reminds him of LEGO. I believe this is a really good analogy and I will elaborate on it using specific examples.

Transforming DMN XML to OpenRules

DMN-OpenRulesOpenRules already can read and execute decision models represented in the DML XML format. To test new DMN-to-OpenRules capabilities I decided to implement DMCommunity’s June-2017 Challenge using the DMN Modeling tool from Trisotech that allows non-technical people to create DMN-compliant decision models and import them to the DMN XML format. My objective was to create DMN XML for the Loan Origination problem described in the Section 11 of the DMN specification and then execute this DMN XML using OpenRules. Continue reading →

Loosely Coupled Decision Models for Loan Origination

DMCommunity.org June-2017 Challenge is looking for the best decision models that implement a well-known Loan Origination problem described in in the Section 11 of the DMN specification. So, I decided to address this challenge using the core DMN constructs implemented in OpenRules. I will describe my solution in the form of dialog between a fictional READER who is assumed to be a business analyst (not a programmer) and the AUTHOR, who represents myself. It is similar to the dialog-sessions described in my recent book “DMN in Action with OpenRules“. While it may look long it doesn’t omit any implementation detail. Besides serving as a good solution for the Challenge, this document describes a good decision modeling practice for OpenRules customers.

Solving Flight Rebooking Challenge With and Without Programming Constructs

DMCommunity.orgFlightRebookingImage announced its Challenge “Rebooking Passengers from Cancelled Flights” in Oct-2016 and until now 4 different solutions have been submitted. It is a relatively complex use case for decision modeling. In this post I will describe different implementation approaches for this challenge and will discuss good and not so good DMN constructs used to support the underlying decisioning logic. I hope this post will initiate more discussions which may lead to the future DMN improvements by replacing the existing programming constructs to more business-friendly representations.

DMN: Iterating Over Arrays Without Explicit Loops

Iteration1I consider myself among the initiators and big supporters of the DMN standard, and I do my best to help bringing the standard to the real-world business decision modeling. Naturally, the current release of DMN includes some constructs with which I strongly disagree but I am trying not to criticize DMN too much as the standard itself is not mature enough yet and I hope it will be gradually improved based on the real-world acceptance.

Raymond Smullyan’s Retro-Analysis and Decision Modeling

When I learned that the famous Prof. Raymond Smullyan passed away this February at the age of 97, I felt grateful to the man whose books and puzzles my friends and I enjoyed reading as young programmers many years ago. Later on we shared them with our children. I wanted somehow to mark this event and decided to buy his book “The Chess Mysteries of Sherlock Holmes” to read on vacation. Ten days ago I started to read the book during my flight from Newark to Jamaica and… haven’t even noticed as we landed. Continue reading →

Happy 14th Birthday, OpenRules!

This week during a conference call with a large potential customer I had shown them our release history. Suddenly I realized that OpenRules just passed its 14th birthday. I remember as we started in 2003 with just a few people and a strong desire to build the best Business Rules Product. And now, 14 years later,  I am glad to share multiple OpenRules success stories at the world largest international corporations and government agencies. In this post I will briefly look back to better understand the factors that contributed to the commercial success we enjoy as a company today. Continue reading →

OpenRules Implementation of the Loan Approval Challenge

loanapprovalimageIn Dec-2016 DMCommunity.org published a new Challenge called “Loan Approval“. This challenge actually was proposed by myself based on real-world experience with one of our customers (a large bank). The most important point of this challenge was a general architecture that allows to invoke the same business logic based on real-time events coming from external sources. I described how such architecture may look like at this video that demonstrates a decision engine integrated with a PUB/SUB message broker.

However, the business logic itself also may be interesting especially if implemented using the latest DMN approach. So, I decided to do a new implementation that is described below. Everything is defined in Excel tables with zero Java code. Continue reading →

New OpenRules Release 6.4.1 with DMN Why-Analyzer

whybutton“Imagine you had a Why Button handy whenever you encountered some disconnect in day-to-day business operations. Hit the Why Button and presto – answers appear in the form of relevant business rules” – Ron Ross, 2013

The release OpenRules Release 6.4.1 introduces a new add-on called “Why-Analyzer for Decision Modeling” that provides such a Why Button for decision models created in accordance with the DMN standard. Actually it is much more than just a button but rather a graphical interface that allows business analysts to analyze the results produced by their decision models using their own test cases created directly in Excel. See a brief video and try it yourself without any downloads from here. There are several more product improvements described in the release notes. You may download the latest release and try your own decision models with OpenRules Why-Analyzer. Continue reading →

Developing Custom Decision Modeling Languages with Enhanced DMN

The modern Business Rules and Decision Management Systems help users to move business logic from a code to business rules controlled by subject matter experts (not developers).  In particular, the latest Decision Model and Notation (DMN) standard [1] defines powerful and broadly applicable concepts for decision modeling that allowed experts [2] to call DMN a “decision modeling language”. DMN even includes a friendly enough expression language, FEEL, to express complex relationships between different decision variables. However, DMN is a general purpose “decision modeling language” that naturally stays away from domain-specific decision modeling constructs. In this article I will discuss how to enhance DMN to support specialized decision modeling languages. Continue reading →

DMN Interchange

The DMN 1.1 standard includes a new interchange format that soon will become public. Meanwhile, DMCommunity Apr-2016 Challenge provides a very simple xml-file for the decision model “Vacation Days” created by Bruce Silver.  Ideally, DM vendors may take this file (and much more complex DMN XML files), transform it to their own format, and execute using their own tools. While vendors are not in a hurry to support DMN XML yet, this weekend I decided to give it a try. Below I will describe the results. Continue reading →
