Improved Agile Estimates

Do you need improved agile estimates? If your agile process is heavily reliant on effort estimates, then chances are that you need to have the best possible estimates. Are your estimates already as good as they can be or do you need improved agile estimates?

Key Agile Practices You Need

Laurie Williams has presented a “top thirty” list of key agile practices. The list defines what you need to do to be seen as being agile. Continuous integration, short iterations and done criteria are at the top of the list.

Agile is NOT new and not enough

So people keep talking about the Agile – Waterfall dichotomy. About agile and un-agile practices. I decided to have an unscientific look at what Agile isn’t. If there is a true dichotomy between Agile and Waterfall, then things opposite of Agile should be either entirely out of scope for projects and software development or they… Read More »

Regression Test Selection

Regression Test Selection or RTS is essential for successful regression testing in larger projects. As long as you are running a small project and working with a small product regression testing is seldom seen as an issue. As your project and product grows and matures your regression test suite becomes increasingly larger and larger. After… Read More »

Agile Estimation Units (revisited)

Is a Driver’s License a Unit Test?

Is it appropriate to call a driver’s license a unit test? Would that be consistent with unit testing best practices? That was part of the discussion that erupted on our internal Yammer network after someone posted a link to coding by numbers. I argued that a driver’s license was not properly a unit test but… Read More »

Agile Configuration Management

I love configuration management! “But”, you ask, “isn’t configuration management boring?” Well, configuration management can be boring and tedious if you do it manually. With modern tools it is not all that bad. Even if it is boring, that is out-weighed by the sheer importance of proper agile configuration management for a successful software development… Read More »

Agile Offshoring in Practice

How is Agile offshoring done in practice? Julian Bass studied seven different companies doing off-shoring London-Bengaluru. He had expected that the companies would have adapted a continuum of practices from Scrum and XP. Findings about Agile Offshoring To his surprise he found that this was not true. Instead, all of the companies had adopted scrum… Read More »

Evidence for XP Practices

In a small study, three different projects were examined with respect to the degree that they used eXtreme Programming practices and what the code looked like in terms of size, complexity and coupling. The conclusion was that more agile practices used in a project lead to lower size, complexity and coupling in the product. The… Read More »

Automated Bug Fixing, Innovation and the Small World of SE Research

With automated bug fixing, we can automatically fix 50% of all bugs at a cost of $8. A fantastic research result from the small world of Software Engineering research. But how can we turn these inventions into innovations? References
