An Introduction to Lean Thinking for Software
For Agile developers only familiar with Scrum or XP, it may be unclear how Lean relates to what they do. This article introduces Lean Thinking and how it enhances software development. Ning Lu of ThoughtWorks China identified the biggest obstacle to Lean or Agile as the mind-set developed during the period of large-scale manufacturing.

Domain Driven Design and Development In Practice
In this article, Srini Penchikala discusses Domain Driven Design and Development from a practical stand-point. The article looks at architectural and design guidelines and best practices that can be used in a DDD project. It also talks about the impact of various design concerns like Persistence, Caching, Transaction Management, Security, Code Generation etc in domain model implementation effort.

Improvement, Success and Failure: Scrum Adoption in China
This recent inquiry, by InfoQ China editor Jacky Li, picked 5 very different cases of Scrum adoption in China, which got different results, and asked: Why did you use Scrum? How did you adopt it? What problems did you encounter, and why did it succeed or fail? Despite the small sample size, it's an interesting comparison, pointing out that improvement doesn't ensure success.

The Three M's - The Lean Triad
The discussion of applying lean principles to software development has largely focused on identifying and eliminating waste (in Japanese: muda). Lean Thinking equally aims to remove overburden (muri) and unnecessary variation (mura). Roman Pichler discusses the relationship of the "three M's" and proposes to eliminate overburden as the first step toward a leaner process.

Kanban Applied to Software Development: from Agile to Lean
In this InfoQ article Kenji Hiranabe applies lessons learned while working with Japanese manufacturers. While many Agile teams are optimizing only a portion of the value stream, Hiranabe proposes a simple way to adapt lessons from Lean Manufacturing's "Kanban" visual tracking system to make process visible to more of the organization, for better communication and process improvement.

Aspects of Domain Model Management
Using a domain model is rarely as easy as just creating the actual domain model classes and then using them. Soon enough one discovers that sizable amounts of infrastructure code will also be required in support of the domain model. In this article, Mats Helander explains how to use Domain Model Management to handle this complexity in a simple way.

Using singleton classes for object metadata
So you have a bunch of objects - let's call it an object graph - provided by some API. Now you want to to process the objects - which requires some intermediate data, for instance: the process creates some metadata that needs to be stored with the objects. The problem: where to store the metadata? We'll show how to use Ruby singleton classes to handle this problem.

The Secret Sauce of Highly Productive Software Development
When Agile teams get stuck in the just-average Norming stage, rather than continuting to the exciting, high Performing stage of teamwork, sometimes they're suffering from an invisible "learning bottleneck" that stunts team performance. Agile practices require us to take time to reflect and learn - and a team that learns quickly succeeds.

Dynamic Routing Using Spring framework and AOP
Vigil Bose shows how a business transaction can trigger business events dynamically for subsystem processing. The examples shown in this article uses Spring framework 2.0 and Spring AOP effectively to decouple the business service from the subsystem processing functionality.

"Real Options" Underlie Agile Practices
Whether we realise it or not, "freedom to choose" is a principle underlying many Agile practices. By avoiding early commitments, we gain flexibility in the choices we make later. In this article, Chris Matts and Olav Maassen propose that an understanding of "Real Options" allows us to develop and refine new agile practices and take agile in directions it hasn't gone before.

Interview: Jezz Santos about Software Factories
InfoQ had a chance to talk to Jezz Santos, a trusted expert advisor for the Web Service Software Factory and the creator of one of the world’s first implementations of a software factory (the EFx Factory), which demonstrates some of the advanced features of a future generation of software factories to come from Microsoft. We questioned him on his view of the Microsoft Software Factory Initiative.

Book Excerpt: Scaling Software Agility
"But does Agile scale?" Emerging stories and case studies indicate that it certainly does. InfoQ brings you two excerpts from Dean Leffingwell's book "Scaling Software Agility: Best Practices for Large Enterprises". Chapter 1 presents how Agile methods respond to the need for competitive advantage, and Chapter 2 revisits "Why the Waterfall Model Doesn’t Work".
