5. Lean and Agile Principles
● System awareness & visibility of the value flow (stand-ups, demos, agile planning & groomings, scrum/kanban boards)
● Empowered, self-organized & feature oriented teams (team autonomy from idea to production)
● Continuous testing & delivery mindset (automated tests, CI/CD, infrastructure as code)
● Continuous improvement & learning (bottleneck elimination, retrospectives, pre/post-mortems, tech talks, conferences,
books, meetups, blogs, dry runs)
● Open culture (trust + feedback + courage + ownership = sustainable development)
● Technical excellence (code reviews, handy tools, best practices & patterns)
● Design & simplicity (UI/UX, usability tests)
● Product discovery & product management mindset (vision, strategy, experiments, prototypes, MVPs, KPIs, AB tests,
qualitative & quantitative user research)
