Team Improvement Kata – Kaizen

Identify End-to-End Value Stream (VS), so “local” optimization is avoided

Identify the waste and document problems in the whole value chain

Developed a solid business case for the key problems and their solutions

Leverage the results from the Initial Maturity Assessment and take them into consideration when selecting the process or a family of processes you want to focus on
