Agile IT Architecture

With my last months studying BPM products, I'm quite impressed by product marketing fliers and other 'best pratices'/ training materials putting emphasis to the fact that traditional, code driven, approach to develop business application is bad, and with BPM it is better to have a unique artifact in a central repository, for managing all the elements of a business application such as UI, information model, service definitions, connectors, business rules, process logic. I'm confused by the lack of applying basic design and architecture best practices such as separation of concern, and artifact life cycle. With monolithic process application, any change to the information model, or the UI enforce migrating all the process instances running on the runtime server. This is interesting to note that SOA reference architecture, defines, UI services separated from process, from data, and rules services. Which makes perfectly sense for re usability, components life cycle, flexib

I got to review a JRules project recently where the developer did used JRules as a graphical programming tool, and not implement rules leveraging the inference and the capability of the rule language. The ruleflow has around 15 subflows that look all like the picture below. The approach chosen was to loop around a collection of expenses and to apply rules in the "Expense" rule task using a variable named 'current expense'. A rule in the Expense rule task, looks like the following statement: if 'current expense' has attendee then <... do something > else print "Expense had no person attached to it" ; First a ruleflow should be used to control the flow of execution of group of rules, grouped together to apply business logic. A ruleflow should not be used as a UI for programming logic. A rule flow stays simple. What is interesting is that JRules as the definitions part in the BAL rules with operator 'in' to

Rational Team Concert 3.0 and previous version provide an excellent environment to develop business application using an agile methodology, and global team. I'm working on a project with resources in china, and multiple States in USA.

The book is about ABRD methodology, architecture, best practices for developing business rule application. I will give more information later. Have fun reading it!. My silence is also due to my current consulting engagements with IBM, so I do not want to say anything about my projects. Also I still need to figure out what I can say outside of IBM.... Learning the business policies of my new company...
