The Improve phase is the fourth step of the DMAIC Lean Six Sigma roadmap. In this step the existing process will be changed and optimized:
  • This process optimization will be based on sound data analysis, a thorough understanding of the relationship between key process responses/performance metrics and key process variables, so this process optimization will be more likely to achieve real results backed by statistical confidence

  • The improvement will take into account Lean applications, typical of Lean methodology and mindset, in order to reduce waste and to increase process efficiency

  • The process optimization is based on scientific approach, real and accurate data. It is not based on subjective judgments
