RE: [rules-users] Drools in the real world
We are using drools in our production software for decision support. We mostly like the decision tables and how easy it is for me to allow a user to modify the rules for a particular installation without me having to write code. We are, in fact, continuing to expand our usage of drools for new facets of our application where the business rules are extremely complicated and vary widely by implementation. -Original Message- From: rules-users-boun...@lists.jboss.org [mailto:rules-users-boun...@lists.jboss.org] On Behalf Of ajay.gau...@rbs.com Sent: Friday, June 12, 2009 9:28 AM To: rules-users@lists.jboss.org Subject: [rules-users] Drools in the real world Are people actually using Drools Or Drools Flow in production?

Re: [rules-users] Drools in the real world
We have been using Drools since version 2, and currently have well over 10,000 rules in production. It is a very solid product that can be used anywhere an Ilog etc would be considered. Drools Flow is a bit new, although I know there are several companies who have it in production. We are currently testing it internally, and it shows huge promise. -Michael - Original Message - From: Ajay Gautam ajay.gau...@rbs.com To: rules-users@lists.jboss.org Sent: Friday, June 12, 2009 8:28:26 AM GMT -06:00 US/Canada Central Subject: [rules-users] Drools in the real world Are people actually using Drools Or Drools Flow in production?

Re: [rules-users] Drools in the real world
Ajay, I don't know what kind of relationship you draw from list traffic to serious adoption. In any case, do some research and you will certainly re-evaluate your metrics. :) Just as a starting point, last week we had the Drools Bootcamp in SF ( http://blog.athico.com/2009/03/drools-boot-camp-san-francisco-june.html), and that is one of the reasons for the reduced traffic in the last couple weeks I guess. Take a look at the attendance list and the companies they come from: http://www.jboss.org/community/wiki/DroolsBootCampSanFranciscoJune2009 Sightings page: http://www.jboss.org/drools/sightings.html Anyway, what I can tell you is that Drools is in really active and constant development, with a growing and energizing community that supports its members in the best possible open source way (thank you all people). On top of that, if you want professional support with SLAs, talk to Red Hat that offers all kind of services around the product (from support to training). Cheers, Edson 2009/6/12 ajay.gau...@rbs.com Are people actually using Drools Or Drools Flow in production? The traffic on this list seems way too low to suggest any serious industry consideration. OTOH, there are books out there for Drools. Which does suggest serious usage. What am I missing? Ajay Gautam *Please note that my email address may have changed.

Re: [rules-users] Drools in the real world
The traffic on this list is quite substantial. Note that it is used if people run into a problem, not when they solve one. Judging Drools' industry usage from the traffic here is akin to saying that fine weather is tied to the Moon being full, which you don't see when it is new nor when the sky is overcast... ;-) -W On Fri, Jun 12, 2009 at 3:28 PM, ajay.gau...@rbs.com wrote: Are people actually using Drools Or Drools Flow in production?
