The Accidental Agilist: A Personal Look Back at 10 Years of the Agile Manifesto

Johanna Rothman reflects on her journey to pragmatic agility. She discusses the way in which agile practices work together to improve project outcomes, and how this is not restricted to software development. She challenges teams to embrace the transparency that agile brings and stop talking about becoming agile and start doing it properly.

Implementation Decision Rationales – Program Comprehension in Agile

Given the fact that the bulk of a developer's work is maintaining and enhancing existing code, Fabian Kiss makes the case for a lightweight approach to documenting the rationale and decision process behind design decisions to help later developers tie the source code syntax to its meaning in the application domain. Using simple tags and clearly thought out rationale to provide just-enough value.

Reflections on the 10 Years Since the Agile Manifesto

Mike Cohn reflects on the changes in software development over the last 10 years, as agile has gone from fringe to mainstream and his hopes that we will move from seeing agile as something different or special, to being simply the way we work. In the same way that the Magna Carta influences our lives without being in the forefront of thinking so the Agile Manifesto should fade into the background

Brian Chess on Static Code Analysis

Building security into software applications from the initial phases of development process is critical. Static code analysis gives developers the ability to review their code without actually executing it to uncover potential security vulnerabilities. InfoQ spoke with Brian Chess about static analysis and how it compares with other security assessment techniques like penetration testing.

A Personal Reflection on Agile Ten Years On

Stephen J Mellor was one of the original signatories of the Agile Manifesto. He attended the Snowbird meeting “as a spy” with but found himself agreeing with most of what was being said and became a proponent of Agile techniques and emphasizes the value of modelling in the Agile world. We rarely see the words “agile” and “model” in the same sentence, but they are not at all in conflict.

Agile Contracts

The traditional Waterfall model fits nicely with the way companies buy things: requirements are drawn up, a supplier quotes a price, and everyone signs a legally binding agreement. Contracts written this way seldom offer the freedom to work using an Agile approach. This article examines four separate models available to suppliers and customers for establishing contracts for Agile work.

Xtext/TS - a Typesystem Framework for Xtext

Since the release of version 1.0, it has become feasible to build complex expression languages in Xtext. However, once you have expressions, you typically also need a type system. In this article Markus Völter describes a framework for specifying type systems for expression languages built using Xtext.
