Externalizing enterprise decision management using service-oriented architecture orchestrated by business process management makes increases agility and allows continuous performance improvement, but…
How do you implement the rules of EDM in an SOA decision service? (more…)
James Taylor’s notes on his lunch with Sandy Carter of IBM and the CEO of Ilog prompted me to write this. Part of the conversation concerned the appeal of SOA and rules to business users. Speaking as a former vendor, we all want business people to appreciate our technology. We earn more if they do. They say to IT “we want SOA” or “we want rules” and our sale not only becomes easier, it becomes more valuable. So we try to convince the business that they are service-oriented, so they should use SOA. Or we tell the business that they have (and make) rules, so they should use (and manage their own) rules. And rules advocates embrace and enhance the SOA value proposition saying that combined, you get the best of both worlds. This is almost precisely the decision management appeal. Externalize your decisions as services and externalize rules from those services for increased agility in decision making. This is an accurate and appropriate perspective for point decision making. But it doesn’t cover the bigger picture that strategic business people consider, which includes governance and compliance.
Effective SOA and business rules have one requirement (or benefit) in common: externalization.
The externalization of services from applications (more…)
James Taylor’s blog today on rules being core to BPM and SOA in which he discussed reuse had a particularly strong impact on me following a trip yesterday. During a meeting with the insurance and retail banking practice leaders at a large consulting firm, we looked for synnergies between applications related to investment and applications related to risk. Of course, during that conversation, we discussed whether operational rules could be usefully shared across these currently siloed areas, but we landed up discussing what they had in common in terms of business concepts, definitions, and fundamental truths or enterprise wide governance. It was clear to us that this was the most fruitful area to develop core, reusable knowledge assets.
In his post, James agrees with the Butler Group’s statement:
Possibly the most important aspect of a rules repository, certainly in respect of the stated promise of BPM, Service Oriented Architecture (SOA), and BRMS, is the ability for the developer to re-use rules within multiple process deployments.
I have several problems with this statement: (more…)
Some strategy folks in an enterprise architecture group recently asked for help making rules more relevant to their organization. Their concerns ranged from when to embed rules in their middle tier versus encapsulate them within services to identifying ideal use cases and reference implementations. They were specifically interested in coupling rules with BPM and BI.
Such questions occur every time a group or enterprise considers adopting rules technology for more than a specific application. They are looking for guidelines, blueprints, or patterns that will help them disseminate understanding about when and how to use rules. They have adopted a BPM vendor which will be integrated with their selected rule vendor, each as enterprise standards, so they are particularly interested in the integration requirements between the two.
Two high level understandings are critical for success in furthering adoption of rules technology.
- abstract activities for which rules technology well-suited and
- when and why rules technology is better than familiar alternatives
