By certifying frontline leaders in Lean Six Sigma Green Belt through the Impruver platform, the team executed targeted improvement projects.

Introduction
The customer operates a complex logistical environment where speed and inventory accuracy are paramount. In the hospitality and resort industry, the ability to move goods efficiently from the dock to the consumer is directly tied to profitability and guest satisfaction. However, operational bottlenecks threatened to stifle their supply chain efficiency. Recognizing the need for a systemic change, the customer sought a partner who could not only teach Lean principles but also drive actual, quantifiable business results through immediate application.
The Problem
The customer was facing a “perfect storm” of logistical challenges that hampered their ability to fill order requirements within their short turnaround windows. The specific pain points were severe:
- Warehouse Disorganization: The warehouse lacked a defined structure, leading to confusion and inefficiency.
- Dead Stock Accumulation: Approximately half of the inventory was dead stock—obsolete items taking up valuable space and capital.
- Operational bottlenecks: Trucks were not being unloaded in time to meet demand, creating a backlog at the main dock.
- Inventory Inaccuracy: Variance in inventory reporting was high, leading to carry costs and lost profit opportunities.
The team needed to quickly sort through the chaos, eliminate the dead stock, and establish a smooth, reliable process for the entire lifecycle of goods—from offloading and storage to retrieval and shipping.
The Solution
To address these deep-rooted issues, the customer turned to Impruver. The strategy was not just training, but applied learning. Impruver certified four of the customer’s frontline leaders—Devaughn R, Cohen S, Dante T, and Rodrique A—in Lean Six Sigma Green Belt.
The solution leveraged the Impruver Platform and Impruver University to drive the initiative:
- Targeted Training: The leaders engaged in comprehensive coursework covering advanced Lean tools and project management.
- Applied Coaching: Utilizing the Impruver Storyboard, the team received structured coaching to set performance goals and track improvements in real-time.
- Project Execution: The certification required the completion of live projects. Each leader was tasked with tackling a specific operational failure point:
- Devaughn R (Warehouse Manager) focused on the off-site warehouse and dead stock reduction.
- Cohen S (Warehouse Supervisor) tackled the dry storeroom organization.
- Dante T (Storeroom Clerk) addressed beverage storeroom inventory accuracy.
- Rodrique A (Dock Master) concentrated on the main dock container offloading times.
Result
The implementation of Lean Six Sigma principles through Impruver generated a massive shift in operational efficiency. In just 10 weeks, the four Green Belt candidates delivered a combined $1.71M financial impact, achieving an ROI of over 100X on the investment.
Key outcomes included:
- Dead Stock Elimination: Devaughn R achieved a 96% reduction in dead pallets, clearing out obsolete inventory and generating $29K in immediate cash from a deadstock sale. This contributed to a $2M increase in working inventory capacity.
- Warehouse Optimization: Cohen S achieved a 75% reduction in dead pallets in the dry storeroom, unlocking capacity that facilitated $1M in cost savings initiatives.
- Inventory Accuracy: Dante T achieved a 90% reduction in inventory inaccuracy, reducing excess inventory variance by $150K.
- Process Speed: Rodrique A achieved a 75% reduction in container unloading time, slashing the time per container from 60 minutes down to just 10 minutes. This efficiency reduced the opportunity cost of lost profit by $0.2M.
By empowering frontline leadership with the right tools and methodology, the customer didn’t just clean a warehouse—they transformed their operational culture.
Conclusion
The customer’s success story serves as a powerful testament to the efficacy of combining Lean Six Sigma education with a robust execution platform. By moving beyond theory and focusing on value creation, they solved critical logistical failures and unlocked millions in value.
For Operations leaders, this case illustrates that the path to operational excellence lies in empowering your workforce. When you equip your team with the right tools to identify and solve problems, the ROI speaks for itself.
