Transforming store productivity through operational excellence

In a highly competitive retail environment, operational excellence at the store level has become a decisive lever for profitability. As labor costs remain one of the largest components of store operating expenses, improving productivity without compromising the customer experience is both a necessity and a strategic opportunity.

Following a broader transformation journey, the organization embarked on a new cycle of performance improvement designed to structurally enhance the ratio between labor costs and sales, ensuring sustainable efficiency without compromising key business indicators.

This case study outlines how a structured, shopfloor-driven approach was used to redesign store processes, starting with the core of the store: the truck-to-shelf process, improving all replenishment processes and strengthening leadership routines.

Starting with a pilot store and evolving into a scalable deployment model, the initiative demonstrates how eliminating waste, creating flow, and building internal capability can unlock significant and sustainable productivity gains across the retail network.

The retailer behind the transformation

The company operates large-format retail stores across Australia. With several hundred stores nationwide and a workforce of tens of thousands, it is a major player in the Australian retail market. Its operating model combines:

• Large-format physical stores supported by e-commerce.
• Centralized merchandising and sourcing.
• A mix of branded and private-label products.
• Distribution through a national and regional distribution center (DC) network.

Building on this operating foundation, the company has completed a significant transformation journey and established a solid performance baseline. The next strategic priority is to launch a new wave of operational improvements designed to structurally enhance the ratio between labor costs and sales, while safeguarding key performance indicators:

• Sales.
• Customer Satisfaction (NPS).
• Employee Satisfaction.
• Stockouts.
• Loss.

The focus shifted to store-level execution — specifically to the efficiency of the truck-to-shelf process, which represents the core operational activity of the business.

The challenge: High labor costs and inefficient product flow

Despite strong market positioning, store-level profitability fell short of expectations due to high operating costs and structural inefficiencies.

The core issue was not isolated to one activity; it was systemic. The truck-to-shelf process, which underpins store operations, lacked flow, standardization, and clear leadership control. As a result, productivity was inconsistent, workload allocation was inaccurate, and labor hours were being absorbed without proportional value creation.

The real barriers to store-level efficiency

A detailed diagnostic phase was conducted in the pilot store to move beyond symptoms and understand the structural drivers of labor inefficiency. Rather than focusing on isolated issues, the analysis examined how activities were sequenced, how leadership routines were executed, and how workload was planned and monitored throughout the day.

This assessment revealed that inefficiencies were not the result of a single bottleneck, but of multiple interconnected gaps across product flow, execution management, and performance visibility. The following key problems were identified as the primary contributors to elevated labor consumption and reduced operational effectiveness.

1. Product flow inefficiencies (Truck-to-shelf)

The truck-to-shelf process was heavily fragmented. Instead of a linear, synchronized flow from unloading to shelf availability, products were being handled multiple times across different locations and activities. The lack of clear sequencing and adherence to standards resulted in congestion, rework, and extended processing times.

Operational observations showed that activities such as sorting and filling were often overlapping instead of being executed in a structured order. This lack of discipline directly affected speed-to-shelf and labor efficiency.

Store visits revealed:

• Multi-touch handling of products from unload to shelf.
• Sorting standards not followed.
• Pallets traveling to secondary backroom locations.
• Decanting performed with customers in store.
• Filling starting before decanting was complete.
• Cardboard movement and congestion.
• Mixed responsibilities between unloading and sorting.

In many cases, the pallets were still being processed at midday, indicating that the load was not flowing efficiently through the system.

2. Filling & inventory execution gaps

Beyond physical flow inefficiencies, execution management gaps were evident. The planning system was disconnected from actual workload, and leadership routines were insufficient to manage variability during the day.

Rosters were created based on forecasted volumes rather than confirmed carton arrivals. This resulted in a mismatch between capacity and workload, manifesting as either idle time or pressure peaks. Additionally, managers were frequently absorbed in operational execution rather than leading, coaching, and pacing the team.

Execution weaknesses included:

• Rosters based on forecast rather than actual carton volumes.
• No detailed daily work plan.
• No progress measurement during the shift.
• Managers frequently filling instead of leading.
• Replenishment during the day overlapping with filling.
• Team members multitasking across processes.
• No daily huddle structure.
• No visual performance measures beyond sales.

3. Performance monitoring & visual management

The operational system lacked visibility and structured performance dialogue. Without clear KPIs beyond sales and without standardized daily routines, managers had limited tools to monitor productivity in real time or address deviations effectively.

Key gaps included:

• No structured KPI routines.
• No visual daily management system.
• No standard pace tool.
• No clear workload allocation before shift start.

Additionally, broader structural factors were influencing execution, such as too many label and planogram changes, mixed pallets from DC, high frequency of replenishment routines, and end of range products overlapping with new products.

The pilot store did not suffer from a lack of effort. Instead, it suffered from a lack of flow, structure, and leadership tools. Labor was being deployed, but not optimized. Processes existed, but were not sequenced. Standards were defined, but not consistently followed.

The opportunity was therefore structural — redesign the system to eliminate waste, create flow, and equip leaders with the tools to manage execution.

Baseline and target

A quantitative baseline confirmed the structural opportunity. In the pilot store:

• Hours used: 1,676 vs. 1,726 forecasted in the labor plan.
• Filling exceeded plan by 75 hours.
• Service hours were partially used to cover filling gaps.

Although total hours appeared below the forecasted labor plan, the distribution of hours revealed internal imbalances. Filling absorbed excess time while other areas underspent, masking the true inefficiency within the truck-to-shelf process.

The target was defined as:

• 8% reduction in total store hours.
• Equivalent to 20% reduction in filling and inventory hours.

The pilot store baseline identified:

• 201 hours per week reduction potential.
• 12% total hours reduction.
• Approximately $360k annual savings.

The objective was not incremental improvement but structural correction. A 8% reduction in total store hours was established as both ambitious and achievable, based on observed waste and quantified inefficiencies in filling and inventory routines.

The solution: Redesigning the store operating model

After clearly identifying where labor was being lost, the solution did not focus on “working harder”; it focused on working differently.

The transformation concentrated on three structural areas:

1. Improving product flow (truck-to-shelf).
2. Strengthening filling and replenishment execution.
3. Creating real performance visibility and leadership control.

Instead of isolated fixes, the objective was to redesign the store’s operating model.

1. Product flow redesign

The biggest inefficiency was not effort — it was a lack of flow.

Products were being handled too many times, moved unnecessarily, and processed in the wrong order. The first step was to introduce a planning tool based on actual carton volumes rather than forecasts. This allowed stores to calculate the real labor required for each load.

From there, the physical flow was redesigned.

Sorting and filling were clearly separated rather than occurring simultaneously. Filling was moved earlier in the day to accelerate stock availability. Sorting was restricted to controlled backroom areas instead of being done on the shop floor.

Operational discipline was introduced:

• Only roll cages are allowed on the shop floor (no pallets or trolleys).
• Knives are banned from the shop floor for safety and control.
• A dedicated runner role was created to reduce unnecessary movement.
• Multi-touch handling was reduced.

The objective was simple: Create a smooth, continuous flow from truck to shelf.

2. Filling & inventory management

The second major shift was managerial, not physical.

Previously, managers were frequently filling instead of leading. There was no structured coaching during the shift and no clear allocation of work before the day started.

The new model clarified roles:

• Store manager focuses on planning, monitoring, and leadership.
• Dedicated fill and sorting leaders manage execution.
• The filling team focuses exclusively on filling.

To support this, new management routines were introduced. To operationalize these routines, a Pace Tool was introduced to define, prior to the start of each shift:

• Which roll cages each team member fills.
• How long it should take.
• What the expected progress should be throughout the day.

To reinforce this structure, daily huddles were formalized and communication routines standardized. Filling and replenishment windows were clearly separated to eliminate overlap, ensuring the team starts and finishes together and operates as a single coordinated unit rather than multitasking across activities.

During the pilot phase, the total time required for filling and sorting activities was rigorously measured, including all related tasks (huddles, unload, waste, runner activities, packaway). This created clarity on the true labor requirement.

Overall, the objective was to shift from reactive execution to structured, progress management.

3. Trial execution

Before scaling anything, the new model was tested in a structured trial. The trial focused on:

• Standardized sorting processes.
• Management progress routines.
• A new sorting layout.

Importantly, the trial was executed without requiring any additional investment, as the existing stockroom space was fully leveraged.

Additionally at the end of each day, structured debrief sessions were conducted with both team members and store leadership, enabling immediate adjustments and rapid iteration.

This reinforced a critical principle: Go to Gemba. Observe reality before making decisions. Direct observation on the shop floor replaces assumptions with facts.

The solution was built from what actually worked on the shop floor — not from assumptions.

Results: When flow drives profitability

The results confirmed that the opportunity was not marginal — it was systemic. By eliminating non-value-added activities, improving flow, and equipping leaders with structured monitoring tools, the store was able to reduce hours while increasing execution discipline and product availability.

Beyond the quantitative impact, the transformation also demonstrated that sustainable productivity gains are achievable when operational standards, leadership routines, and workload planning are aligned.

Pilot store results

The pilot delivered measurable results:

• 201 hours saved per week.

Beyond the numbers, the operational impact was visible:

• The physical process is now followed as designed.
• Store is filled as a team, not in silos.
• The stockroom became cleaner and fully decanted.
• Stock reaches the shop floor faster.
• Product availability improved, including online.

Most importantly, the project instilled a strong belief that stores can operate with fewer hours without compromising the customer experience.

Scaling the transformation

After validating the pilot, the next question was the scale. Under a moderate rollout scenario, the full deployment represented:

• An 12% decrease in total hourly labor spend, applied to a $508M annual wage base (excluding salaries), generating an estimated $61M in yearly savings.
• The full financial impact will be captured by 2027.
• 39-week program timeline.

This transforms the initiative from a store project into a structural lever of profitability.

Deployment model

The rollout followed a structured wave approach to ensure quality and sustainability.

It started with a Pilot, followed by several waves. Each wave includes:

• Training sessions for store leaders.
• On-site deployment support.
• Process confirmation and audit.
• Preparation for the next wave.
• Recognition for stores that meet standards.
• A workshop to teach leaders how to identify waste (“Waste Goggles”).

This structured sequencing prevents overload and builds capability progressively.

Governance structure

Scaling required discipline, not just enthusiasm. Three main roles supported the rollout:

Kaizen consultants

Guide process improvements, remove barriers, and transfer capability.

Group managers

Lead store managers, ensure standards are followed, and resolve people and roster issues.

Internal project team

Remove cross-store roadblocks and align stakeholders.

Lessons learned

The scale of change requires a strong leadership presence on the shop floor. Standards alone are insufficient; coaching and active involvement from managers is necessary.

Two layers of improvement were critical: improving rostering based on actual carton volumes and strengthening execution discipline through leadership routines.

Additional opportunities remain above-store, including DC pallet configuration, markdown optimization, labeling processes, planogram changes, and product lifecycle synchronization.

Conclusion: Sustainable productivity through structured transformation

This transformation demonstrates that significant labor productivity improvements are achievable without compromising customer experience or sales, by:

• Redesigning truck-to-shelf flow.
• Introducing workload-based planning.
• Equipping managers with monitoring tools.
• Standardizing execution.
• Embedding governance and capability building.

The transformation is self-funded, structured, and sustainable — combining operational improvement with leadership development.

Through a structured Kaizen-based transformation, the retailer significantly improved store productivity, reduced labor costs, and enhanced product availability. By redesigning core processes, clarifying roles, and equipping leaders with the right tools, the company established a scalable operating model capable of sustaining continuous improvement across its store network.
