We’ve said many times that the principles aren’t that modern, and aren’t about testing. These evolved during our discussions on how we were seeing (and still see) people who were testers in the early days of Agile and rapid releases provide value to their teams in new ways. In many ways, these are delivery principles, but we’re not going to change the name. MT Principles 2.0 Our priority is improving the business. We use models like Lean Thinking and the Theory of Constraints to help identify, prioritize and mitigate bottlenecks from the system. We are a force for continuous improvement, and adapt and optimize our practices in order to succeed, rather than using safety nets to catch our failures. We care deeply about the quality culture of our team, and we coach, lead, and nurture our team towards a more mature quality culture. We believe that the customer is the only one capable to judge and evaluate the quality of our product We use data extensively to deeply understand customer usage and then close the gaps between product hypotheses and business impact. We expand abilities and knowhow across the team; understanding that this may reduce (or eliminate) the need for dedicated specialists.
