If you are modeling a decision, it is likely that you will want to make use of an enumeration, that is, a data type which restricts the options to a fixed set of values. I tested this on four different DMN modeling tools, and I found the output is different for the different tools. That has implications for interoperability.
Continue readingI was recently asked to do some decision modeling in DMN. This is an update on the tools that are available as I experienced them today.
Continue readingIt was at the bpmNEXT conference three years ago that I was persuaded to start the DMN TCK group to strengthen the DMN standards effort. It has turned out better, and accomplished more than I imagined.
Would you release a product to the public before you run the tests? Whether you are manufacturing, or software, or agriculture, or anything, if you have a set of tests, you would run the tests before providing the final product to the pubic. Makes sense, right? The world of technology standards is different. Continue reading
Attending bpmNEXT conference this week. It was here, two years ago, that we decided to start the DMN TCK effort. How far have we come? Continue reading
The DMN TCK is a group of people united around a single desire: we want to see DMN succeed as a decision modeling paradigm. We want it to really work, and not simply be another passing fad. We want transparency of what the particular implementations can and can’t do, and we want an independent way to verify vendor claims. Do you have a vested interest in DMN? Maybe you should consider joining the TCK team to reduce your risk, and to assure the success of the DMN marketplace. Continue reading
Last year we started the Decision Model & Notation Technical Compatibility Kit (DMN-TCK) working group. A lot has happened since the last time I wrote about this, so let me give you an update. Continue reading
The new expression language for Decision Model and Notation standard is called the Friendly Enough Expression Language (FEEL). Over all it is a credible offering, and one that is much needed in decision modeling where no specific grammar has emerged as the standard. But I found the handling of date and time values a bit odd. Continue reading
The initial Decision Model Notation TCK test results are in! The web site is up showing the results from three vendors. Continue reading
bpmNEXT is 2 and half days of intense examination and evaluation of the leading trends in the business process community, and Decision Modeling Notation was clearly highlighted this year. Continue reading
