Epsilon Bank is struggling with high variability in its mortgage application approval process, leading to a long and unpredictable lead time. A Six Sigma (SS) project team calculates the current process capability to be 3.5 Sigma. The team proposes to reconfigure the approval process from a traditional sequential flow to a Cellular Manufacturing or One-Piece Flow layout. What is the primary Six Sigma objective that the One-Piece Flow layout directly supports, and what improvement is expected in the defect rate (DPMO) if the process is improved to a 4.5 Sigma level?
