Article: Process Component Models: The Next Generation In Workflow?
Tom Baeyens wrote a summary of the state of Workflow & BPM standards and tools. After a detailed look at BPEL, BPMN, and other technologies such as choreography, XPDL, BPDM, jPDL, Tom takes the stance that it is time to abandon the idea that non-technical business analysts can draw production-ready software in diagrams and separate the analysis process models and executable process models.

Prefer Broad Design Skills over Platform Knowledge
In his latest article Martin Fowler suggests that what matters most while building a team is not experience or thorough knowledge of the specific platform and business domain, but rather some broader skills that allow building quality software and delivering value.

Concept Programming
Looking for a way to cope with the increasing complexity in software? Concept programming introduces a new way to look at how software is conceived and created, by closing the gap of how you represent the business problem concepts in your head and in code.

InfoQ Presentation: Eric Evans on DDD - Strategic Design
In this talk, Eric Evans introduces two broad principles for strategic design. 'Context mapping' addresses the fact that different groups model differently and 'Core domain' distills a shared vision of the system's core domain and provides a systematic guide to when good enough is good enough versus when to push for excellence.

InfoQ Minibook: Composite Software Construction
In a new InfoQ minibook, InfoQ SOA Editor and SOA Enterprise Architect Jean-Jacques Dubray describes the state of the art and emerging new approaches in building "Composite Software", solutions created by assembling existing services. The book is available as an InfoQ Minibook, i.e. free of charge in PDF format for InfoQ users. A printed version is available too.

Designing for flexibility and robustness: Asynchronous message model, OOP and Functional Programming
According to Pragmatic Programmers it is preferable in OOP to avoid design based on returning values. Michael Feathers argues that it may also be better to use the asynchronous message model that might be instrumental for improving adaptability and robustness. This maps well to the Erlang model though opposing some of the principles of pure functional programming.

Is a picture always worth a thousand words?
<p>Is a picture always worth a thousand words?</p> <p>In his recent article, “Why we write code and don’t just draw diagrams”, Dean Wampler argues that in software development the opposite is more often true. </p>

InfoQ Presentation: Eric Evans on Domain Driven Design - Putting the Model to Work
Why bother with models? Eric Evans explains that the most critical complexity of most software projects is understanding the business domain itself. In this talk Evans talks about the foundations of Domain-Driven Design and how to make a domain model truly pull its weight and positively transform a project.

OOP: Thinking beyond verb/noun metaphor to yield a better design
In OOP, objects are traditionally coupled with actions that determine their behavior, implemented as objects’ methods. Reg Braithwaite argues that, in some cases, it may be relevant to dissociate the two. Traditional approach to OOP is also questioned by Buko Obele who advocates for going beyond the verb/noun metaphor that is often used to approach object oriented design.

Erik Doernenburg on Software Visualization
Software visualization aims to provide a representation of artifacts at an intermediate level of abstraction, which provides enough information to be useful but is at a high enough level that you can perform broadly scoped analysis. In this interview Erik Doernenburg talks with InfoQ about different software visualization strategies using a combination of free tools and custom development.

High abstraction level of DSLs to reduce the testing burden?
Inconsistencies between the user interface and user’s expectations can be an important source of bugs. According to Leonardo Vernazza, this is due the fact that the user and the UI do not talk the same language. Using a DSL, characterized by a high abstraction level, would be instrumental for avoiding the risk of translation errors and would therefore reduce the testing burden.

Language-oriented programming : an evolutionary step beyond object-oriented programming?
At a recent conference, Martin Fowler and Neal Ford develop the concept of language-oriented programming and question the eventuality for Domain Specific Languages to become a new abstraction and modelling mechanism. This could be "the next evolutionary step beyond object-oriented programming", especially since major vendors start offering IDE tooling for DSLs.

Interview: Eric Evans on Domain Driven Design
Ever since Eric Evans wrote the book Domain-Driven Design in 2004 he has been a significant voice advancing domain modeling and design concepts. In this interview with Floyd Marinescu he talks about some of the recent refinements in Domain-Driven Design and how people are advancing the field today.

IBM Updates Architect Content/Info Kit
IBM in May updated their "Software Architect Kit", a bundle of content for architects including podcasts by Grady Booch on trends, patterns and best practices in architecture, webcasts, demos, and whitepapers on patterns-based development, SOA, model-driven architecture, and software structure & modularity. The kit requires registration before all the content can be downloaded.
