Even in organisations that haven’t embraced a Lean|Agile approach to software development, Lean principles can help make a difference. Adam and Jo explain how Lean testing methods employ the principles of Lean software development to enable more effective and more efficient testing practices in any organisation or project, regardless of the development mindset or methodology. Drawing from their practical experiences in implementing such techniques, Adam and Jo will show how Lean testing helped transform a traditional, Waterfall-based project, but also highlight that Lean testing is an essential addition to the testing toolbox in any organisation that has already embraced Lean|Agile development practices.
