Preparation tips
- Choose a recognised certifier (ASQ or IASSC) and study to its exact body of knowledge — they are not identical.
- Master the DMAIC phases and the core statistics and tools.
- Practise applying tools to data, not just memorising definitions.
Common mistakes to avoid
- Assuming all Green Belt certifications are the same when the exams and rules differ.
- Learning tool names without practising the statistics behind them.
