Business Rules

[Hugo]

Hi

I notice the concept of business rules is discussed and appears all over in EA documentation and literature.

However I cannot find a "BusinessRule" element.

Our understanding of business rules is that they differ from requirements and provide a means for defining a business defintion or processing rule in a single place.

Other elements like decisions for example, can then realize not only requirements but also these rules, and the rule may be chnaged in a single place for the whole model to remain self-consistent.

Does this exist in EA?

Thanks

"Business Rule" is not a UML element, at least as far as the specification is concerned.

That said, there is obviouly a lot of potential for improvement of EA by somehow encapsulating this as some kind of extended element - perhaps something like Requirement or Issue.

Considerable thought needs to be put into this, as it would be very easy to come up with something that would seem half-baked in hindsight.

In the meantime there has been a lot of high quality discussion about this in the forum. There have also been some good approaches to representing business rules in models. You should take the time to do a search. [Hint: search on businessrule (without a space) as well.]

I simply use a stereotyped Requirement for this purpose.

I simply use a stereotyped Requirement for this purpose.

I do the same and I am happy with it. Though special element like Issue is, would help.
