What are the best case studies of Lean Six Sigma in service industries?

A good example comes from Stanford Hospital a few years ago. At the time, each surgeon specified a “personalized” surgical tray of instruments for each operation. For every surgical procedure, there was a different surgical tray for every surgeon on staff. This personal preference had little impact on the quality of patient care. After some negotiations, the cardiac surgeons agreed to a standardized configuration for all surgical trays. Non-value-added steps were eliminated and process variability was reduced, along with a tremendous savings in costs and time. They went on to apply this same approach to all surgeries and service processes. I discuss this, and more, in my course: https://www.dhirubhai.net/learning/lean-six-sigma-foundations

Heath Care Sector is one place where leaning existing processes is essential to reduce hallway wait times. Current processes include repetitive and time-consuming tasks with meticulous paperwork adding to the administrative burden of not only emergency departments but also Walk-in Clinics. Digitalization and streamlined communication between teams can be enabled by following the DMAIC framework there by not only increasing service quality but also improving efficiencies where possible.

Incredible results with Lean Six Sigma in healthcare! The 74% reduction in SSIs at a US hospital highlights the critical impact of the DMAIC framework and evidence-based practices. This case is a powerful testament to how structured process improvements can save lives, cut costs, and elevate care quality. It's an inspiring example for healthcare institutions globally to adopt LSS methodologies for better outcomes

Loan processing at a bank in India struck a chord! They managed to cut down waiting times by 60% and up approvals and happiness all around. It just goes to show that when you simplify things and bring in a bit of automation, it's not just the numbers that get better people feel it too. This kind of change makes banking feel more personal and responsive, something we all can appreciate. It’s a great reminder of how thoughtful improvements can make a big difference in our day-to-day experiences.

I’m truly inspired by the transformative impact Lean Six Sigma has had on the hospitality industry, especially with the achievements of a UK hotel chain. Halving customer complaints, elevating their Net Promoter Score, and achieving a staggering ￡1 million in savings are milestones that speak volumes. It’s a testament to the power of refining core processes: streamlining check-ins, ensuring impeccable room standards, and genuinely valuing guest feedback. Such strategic improvements don’t just cut costs; they create a legion of loyal fans. It's a brilliant showcase of how prioritizing quality and customer experience drives success
