Occasionally in my BPMN Method and Style training, a student will submit a Certification exercise containing a Conditional event. I have always rejected that. Conditional events are not part of Method and Style, and that's because I have always considered them to mean "some magic occurs". According to the spec, a Conditional event may be [...]
As a followup to my post from last month, there is another aspect of datatypes I've been thinking about. When a simple type is subject to constraints, such as a numeric range or a list of enumerated values, I have been teaching students to create an item definition that expresses those constraints. For example, if [...]
In my DMN Method and Style training, we cover a lot of advanced topics, including calendar arithmetic, iteration, filters, and data validation. But I have found that problems in students' certification exercises more often relate to something much more basic, which we discuss at the very beginning of the course: assignment and naming of datatypes. [...]
For many years my work has focused on non-executable BPMN using a set of conventions called Method and Style. In the past year or two I have turned my attention to Low-Code Business Automation, based on executable BPMN. When I wrote my book BPMN Method and Style - over a decade ago! - I imagined [...]
As we discussed earlier this year, a key factor in the growing popularity of Low-Code Business Automation is the availability of REST APIs for just about anything you need to do. REST APIs provide a simple uniform interface based on the standards of the World Wide Web, so they work the same way with any [...]
Cloud datastores are a new feature of the Trisotech Automation platform. They are most useful in BPMN, but they can serve also as input data in DMN. Datastores are a standard BPMN element representing persisted storage, accessed by a process task via data association but available for external access as well. In Trisotech's implementation, each [...]
Ten months in the making, I'm happy to announce that my Low-Code Business Automation training and certification is at last available. While there are many Low-Code Business Automation products available, they all use proprietary modeling and expression languages. Trisotech does not. On the Trisotech platform, you can create complex event-driven workflow services and pageflow apps [...]
With the imminent launch of version 11 of the Trisotech platform, I am happy to announce a new version of my DMN Method and Style training, effective immediately. Previously I offered two courses, DMN Basics and DMN Advanced, in which the focus of DMN Basics was top-down logic decomposition using Decision Requirements Diagrams (DRDs) [...]
Recently I viewed a DecisionCamp presentation on an application of DMN to a public-facing portal in the Netherlands for what we call in the USA building permits. Here is the link. The scope of the project is impressive, combining regulations defined at the national, provincial, and municipal level, plus those of special districts. The ultimate [...]
Here's a thought: What if the greatest opportunity for DMN is not decision management? Over the past year, I have come to this conclusion, and that greener pastures lie in the direction of Low-Code Business Logic. Its addressable market is far larger, and there is less organized resistance among incumbent vendors than DMN faces in [...]
