TDD/BDD Leading To Incomplete Unit Tests?

Does Continuous Production Lead To Extreme Agility?

Measure Teams, Not Individuals
Michael Dubakov recently expressed warning against the measurement of individual velocity and individual estimate accuracy. His view: measurement of these metrics not only provides no more useful information than is already available with their team-level equivalents, but may also have a tendency to encourage teams into behaviors that reduce effectiveness.

Are Iterations/Sprints Waste or Value to Agile Teams?
Although many people consider iteration to be a key characteristic of agile software development, some question whether or not they're important, and add value to an agile method, or if they're superfluous, or even wasteful. InfoQ has assembled a roundup of arguments on the subject, to help agile teams decide if iterations are important for them.

Does TDD Really Ensure Quality?
Analysis of a recent study by the National Research Council of Canada's Institute of Technology into Test Driven Development turned up some interesting observations regarding the value that this approach adds, including whether, in fact, it adds any more value to the quality process than testing after development.

Iterating and Incrementing to 'Get What You Need'
In "Don't know what I want, but I know how to get it", Jeff Patton described a few ways in which Agile teams and business users miscommunicate, and argued that the agile community needs to be clear about the terms 'iterating', 'incrementing' and 'shippable'.

Mythical Agile Shortcuts
Going agile seems a pretty trivial task. We pair up, write unit tests, integrate regularly and support our teams with an easy to manage framework such as Scrum. In reality, however, this is not the case. All too often the benefits are not achieved and team does not function as expected. Ross Petit's recent article sheds some light on why things go wrong when the rubber hits the road.

Creating Better Metrics
A recent article in The Economist pays tribute to three of the finest graphics from the last two centuries. What can be learned from these graphics to improve the display and the quality of agile development metrics?

The Power of Checklists
In a recent New Yorker article, Atul Gawande describes how Dr. Peter Pronovost is dramatically decreasing infection rates in hospital intensive care units with "stupid little checklists". If simple checklists can save lives, can they improve your agile development team?

Evidence Based Scheduling and FogBugz 6.0
Joel Spolsky recently posted an article about Evidence Based Scheduling. The post focuses on managing and identifying good estimates, in turn allowing the project manager to forecast the probability of delivering on a given date, adding a new method of measurement to the agile project manager's toolbox. InfoQ investigates the theory behind the practice, and its implementation in FogBugz 6.0.
