Verizon implemented a tailored version of Lean Six Sigma called VLSS to transform its culture and improve processes. One initial VLSS initiative focused on training effectiveness and resulted in $4 million savings by 2012. VLSS uses experts to guide continuous process improvement. Key steps include identifying gaps, implementing changes, and monitoring sustained results. Certifications like Green Belt and Black Belt are offered to employees working on process improvement projects. The DMAIC framework of Define, Measure, Analyze, Improve, Control is used. Benefits include cost cutting, reduced waste, and streamlined processes.
