"In my opinion, OpenRules has the best technical support, which is very helpful in evaluation stage. We paid 50 dollars up front, but get much valuable advice. That is good." Zi, Gang, Developer at USPTO, 2014
"I would strongly advise use of a business decision analysis technique, like the Decision Model (TDM, http://www.thedecisionmodel.com), and the use of a BDMS (for example, OpenRules) that allows business users to capture, validate and test their decision logic with minimal (but well specified) IT involvement." Jan Purchase, Solution Architect at Deutsche Bank, 2013
"Our experience with OpenRules has been largely positive. I have really enjoyed working with your product." Simon Liao, Software Engineer, Compressus, firstname.lastname@example.org, 2012

OpenRules have the most-aggressive approaches to business-expert authoring and typically requires less developer support than IBM ILOG, FICO Blaze Advisor, and JBoss BRMS Market Overview: Business Rules Platforms 2011", Forrester Research, July-2011
believe that OpenRules Decision Modeling is exactly what we need to gain the
upper hand over the 9000+ business rules in the system. I subscribed to
OpenRules and I have worked my way through more than half of the tutorials. They
are well written; easy to follow; and clearly demonstrate the declarative
nature, traceability and clean interfaces of the implementation."
Alex Karman, Chief Engineer, OGSystems, Jan-2012
Thank you for developing such groundbreaking software capabilities Smooth Profit Accelerators, StephenKClark@yahoo.com, 2011
"The OpenRules engine is very intuitive, and powerful, at the same time. It enables our product specialists to implement new business rules themselves, in Excel files, as opposed to having to work with a software specialist, which inevitably takes more time. Furthermore, the support has been fantastic!" Peter Link, Regal Beloit Corporation, Peter.Link@regalbeloit.com, 2010
"Thanks so much for your help! The support I get for this framework (for free!) was the deciding factor to go with this BRMS, as opposed to JBoss Rules/Drools, Jess, or ILOG JRules." David Rosenfield, email@example.com, 2010
"We use OpenRules as part of a hospital infection surveillance application, with rules designed to identify suspicious lab results based on a variety of clinician-defined conditions. We found the tool easy to incorporate into our J2EE application and easy to customize. Our clients love the ability to compose rules in Microsoft Excel, a fact that is an instant hit whenever we demonstrate it." Bimal R. Desai, MD, MBI, Pediatrician, Clinical Informaticist,
"The more I use OpenRules, the more respect and admiration I have for what you have accomplished. Thank you for your prompt and cogent replies to every one of my inquiries!" Christopher Skelly, Senior SOA/BPM Architect, Insight Resource, Inc., 2008
"The latest OpenRules advances allow us to dramatically minimize the size of our rules repository. Rule templates become a blessing for our complex patent processing rules that have to support data streams from more than 80 different countries." Rex Bosma, Manager of Data Flow Operations, European Patent Office, 2008
"OpenRules is an example of a rules-based OSS BI application.
It offers a methodology, along with OSS tools and professional services for
business analysts rather than or in concert with developers. This is an
interesting approach and an approach that will be important in the long run to
grow all categories of OSS applications."
Dennis Byron, Analyst, ebizQ, review "Open Source Business Intelligence Megatrends", 2007
"The biggest advantage of using OpenRules Engine lies in its flexibility to change the business rules in the Excel sheet at run time and have these reflected in the application – requiring no additional build, deployment or server startup. Add to that, the fact that it easily integrates with existing web applications also results in a smaller learning curve and easier adoption." P.N.Subramanian, firstname.lastname@example.org
"I enjoyed working with you and your software and I will definitely be looking for further opportunities to apply OpenRules." Mark Holt, Lead Technical Architect, ABN AMRO, London
"Thanx heaps, you guys are really great and
full marks for being Proactive!"
Don Whiteside, Solution Architect, Vero Insurance New Zealand Limited, 2007
"I was investigating the use of OpenRules in an application and was very impressed with the flexibility and performance it provides. The ability to use a simple smart interface such as MS Excel to implement your rules and the ease of use with the Java API and conformance to JSR94 are all positives of the engine I would have no hesitation to recommend it to colleagues. Thanks for all the hard work." Harvey Raja, email@example.com, 2006
"What a cool way of creating a comfortable
middle-ground between business and technical rules-based development."
Tim Rohde, E2P, 2006
"Thank you very much for your kind assistance. After applying
the changes suggested by you, I was able to run my BEA application successfully.
I am greatly impressed by the way support was provided."
Nitesh Gautam, firstname.lastname@example.org, 2006
"Two factors make OpenRules immediately
appealing - using Excel as the rules store and the excellent documentation
Dammian Miller, http://shinetech.com/, 2005
"Wow! Excellent job. Now with OpenRules
2.1.0 , I'm able to compile and run the demos, both on Mac OS X and on Linux
(Mandrake). As a test, I tried making some modifications to both the Java source
files and the XLS file (using OpenOffice.org) in the HelloJava demo, and had no
problems getting it to rebuild and run. Now that I can actually run the examples
I can see that it's every bit as slick as I was hoping it would be. The
distribution structure is definitely more multi-platform friendly. Kudos to the
developers for making these changes so quickly."
Steve Jakob, http://www.wideskies.ca/, 2005
"I am glad to report that problem was solved
by your proposal and Japanese was displayed correctly. As the result, everyone
can make a Web application in a Japanese environment by using OpenRules. We
express our sincere gratitude for your cooperation."
Hiromi Okada, http://www.blowline.co.jp, 2005
"It took me 6 hours total to integrate OpenRules with our Orion J2EE Server! I recall it took me 2 weeks to get the same rules going in ILOG!"
Patrice Gagnon, http://www.bricsnet.com, 2005
"I like the way the decision table is incorporated in Excel."Prof. Jan Vanthienen, http://www.econ.kuleuven.ac.be/tew/academic/infosys/research/prologa/prologa.htm, 2005
“OpenRules enables GraphiteStore not only to be more efficient, but also to be more responsive to the constantly changing and expanding product lines.” Vladimir Novokhovsky, General Manager, http://www.graphitestore.com, 2005
"I've successfully deployed several Web
services in an evaluation prototype using OpenRules 2.0, and defining
datatypes in Excel. I'm interested in using pre-existing Java classes with
the OpenRules decision tables and methods, to facilitate communication of
the Web services with other services and components in the overall process."
Paul R Camann, http://www.csc.com, 2005
