Lean Assumptions

Lean assumptions are basic beliefs or expectations made during process improvement efforts that guide decision-making. They help teams identify what they think is true about a process, such as what causes delays or defects, without having complete evidence. Recognizing these assumptions allows teams to test them through experiments, reducing risks and ensuring solutions are based on facts. Essentially, lean assumptions are educated guesses that, when validated, lead to more efficient, waste-free processes and better outcomes.
