Project Details

Project Title: Speed & Safety Experiment

Company Name: Target Corporation

Program: Replenishment Process Optimization / Safety & Efficiency Initiative

Location: Fifty (50) stores in South Florida

Role: Pilot Operations Manager/ Project Manager for Expansion

Timeframe: 2013 (one year) / 1 Month Pilot, 2 Month Test, and 9 months for Full Adoption.

The Challenge

Who: Logistics and Replenishment teams across a high-volume 50-store group.

What: The organization faced a "triple-negative" operational failure. While attempting to speed up replenishment to cut costs, the incident rate spiked to 6.2 cases per 100 workers. This rush caused process breakdowns, dropping in-stock rates to 85% (empty shelves) and ironically increasing the workload for other teams due to rework.

Where: In the back-of-house receiving docks and sales floors, specifically during the high-intensity truck unload and replenishment shifts.

When: During a period of aggressive payroll reduction targets where stores were operating on approximately 110 hours per truck or 1,100 replenishment hours per week but failing to clear volume efficiently.

Why: Teams were confusing "speed" with "rushing." With an average of 10 trucks per week carrying 2,000 cartons each, backroom teams were spending 80 labor hours per truck just to back-stock the freight and pull later from system generated requests. Teams were staffing almost the entire team to unload quickly, to then be looking at freight scattered across departments with everyone exhausted from unloading quickly. This was highly inefficient leading to fatigue, injuries, rework, and ultimately a failure to get product to the shelf

Advisory

The Insight

We analyzed the flow of 20,000 cartons per week against the standard 110 labor hours allocated for each truck with 80 hours for backroom functions. The data revealed that injury spikes were perfectly correlated with chaotic unload processes, broken product and messy work areas."

The Big Idea

"Standardized Safety IS Speed." We hypothesized that by slowing down the movement to follow a strict, safe cadence, we would actually speed up the outcome. We proved that a deliberate, organized flow reduces "touch-time" per carton, creating a fuller store with less physical exertion while improving brand and instock levels.

Strategy

Timeline

Phase 1 (Baseline): Root Cause Analysis of the 190-hours-per-truck (110 Unload, 80 Back-stock) inefficiency. Single store experiment moving Back-stock payroll to auditing and assisting with unload/stocking. Developing a standard playbook for stores.
Phase 2 (Pilot): Implemented the "Speed & Safety" protocol in 7 strategic locations. Supported strategic rollout and refined SOP for broader usage.
Phase 3 (Rollout & Competition): Scaled to all 50 stores in the group once the pilot proved that safe processes yield higher instock rates and reduced overall payroll usage.

Framework / Model

We utilized a Root Cause Analysis (RCA) framework to identify specific friction points in the unload line, followed by Standard Operating Procedure (SOP) deployment to eliminate variability.

Empathy (The Employee View)

To ensure adoption, leadership (including myself) physically worked the lines at pilot stores for weeks.

The "Why": We demonstrated to the line workers that their chaotic "rushing" was actually creating more work for the sales floor teams.
The Connection: We showed them that by sorting accurately and safely on the dock, they eliminated rework for their peers, resulting in a perpetually fuller, "on-brand" store with less total effort. This connected their backroom labor directly to the customer experience.

Gaming (Incentives & Behavior)

We gamified the transformation to drive engagement:

Internal Competitions: We established leaderboards tracking Speed (Cartons per Hour), In-Stock %, Backroom Location Usage % and Safety Incidents.
Benchmarking: Once baselines were established, we set aggressive but achievable goals for stores and monitored through weekly calls and metric dashboards for key metrics.

Accountability

Weekly operational calls were used not just for reporting, but for "public glory" where top-performing stores shared best practices, driving a competitive spirit to be the "safest and fullest" store in the group.

Management

The project was managed through a Continuous Improvement Loop:

Standardization: We created a documented "Speed & Safety" unload process, removing ambiguity from strategy. We provided calculators to forecast payroll based on truck predictions.
In-Person Training: We rejected "read-and-sign" training. Instead, we conducted in-person sessions at every store to build muscle memory for the new process. We gathered Champions or SME’s from each store to help spread the benefits through experience.
Feedback Loops: We established a weekly accountability process to review payroll utilization against carton flow, ensuring that efficiency gains were sustainable and not just a temporary burst of effort. This also allowed for additional improvements to be suggested and expanded into other processes like merchandise display redesigns and clearance markdown strategy to also gain improvements.

Power Thought

Quantitative Results:

Cost Savings: Decreased payroll usage by 4%, resulting in $20M annual savings.
Revenue Growth: Increased in-stock rates from 85% to 94%, driving a 6% increase in total sales.
Safety: Reduced the incident rate from 6.2 cases per 100 workers to 2.3 (a 63% reduction), significantly lowering Workers' Compensation claims.

Qualitative IMPACT:

Identity: Shifted the logistics team's identity from "Backroom Grunts, Clean-Up Crew” to "Revenue Generators/In-Stock Champions."
Mission: Aligned the entire store on the mission that "A great logistics process means a safer store, increase in sales, and balanced workload across teams."
Purpose: Every backroom action will be linked to a customer experience, ensuring each move contributes to a customer centric strategy and moving away from arbitrary unload speed metrics.
Attitude: Moved from a defensive posture (placing blame externally) to a proactive posture (competing to have the fullest and safest store while also owning opportunities).
Core Values: Identify inefficiencies, take action, measure results and share your learning. Deliver Results incrementally across processes.
Trust: By working the lines alongside the teams, leadership restored trust. Workers realized the new process was designed to make their lives easier, not to cut their hours.

External Sources & Benchmarks

To validate the significance of these results, we can reference the following industry standards:

Safety Incident Rate:
- Benchmark: The Bureau of Labor Statistics (BLS) and OSHA report the average Total Recordable Incident Rate (TRIR) for retail trade is typically between 3.0 and 3.5.
- Comparison: Reducing your rate to 2.3 places your operation significantly safer than the industry average, validating the "Speed & Safety" hypothesis.
- Reference: OSHA/BLS Retail Industry Injury Statistics
In-Stock & Sales Lift:
- Benchmark: Research by McKinsey & Company and Harvard Business Review consistently shows a strong correlation between On-Shelf Availability (OSA) and sales. A 3% increase in OSA typically correlates to a 1% increase in sales.
- Comparison: Your 9% increase in in-stock (from 85% to 94%) correlating to a 6% sales lift aligns perfectly with these global supply chain standards.
