OAK4 Inbound and ICQA
Operations Manager at OAK4 (Amazon's Oakland fulfillment center) from December 2014 to October 2016. Owned the Inbound (IB) department across two operational phases (IB Round 2 and IB Round 3) plus the ICQA (Inventory Control and Quality Assurance) function. Inbound is where shipments arrive at the fulfillment center and get inducted into the storage and retrieval system. ICQA is the quality control function that ensures inventory integrity (right item, right count, right location).
Two operational layers ran in parallel. The shift execution layer (300+ associates working a daily shift to hit volume targets and quality bars) and the standardization layer (Standard Work documents, problem-solving processes, Kaizen events, headcount planning, station mastering) that allowed the shift to run consistently across leadership rotations.
Standard Work Artifacts I Authored or Owned
The standardization layer. Each artifact converted operational practice into documented process. Multiple iterations on each one as the operation matured.
PSolver Task List. Three Iterations
The Problem Solver task list went through three versions during the role. Each version reflected what the operation had learned about how PSolvers should integrate with stowing, receive, and inbound flow.
Team Leader Pipeline. The Mechanism Behind 11 Promotions in 3 Months
Designed the Team Leader role with experienced associates leading 8 to 10 stowers. The pipeline produced 11 promotions to leadership in 3 months and 15% stow rate improvement.
IB Round 2, Round 3, and Kaizen
The IB department operated in two distinct phases during the tenure: IB Round 2 and IB Round 3. Each phase had its own configuration of Standard Work, station masters, headcount planning, and Kaizen-driven improvements. The Daily Plans folder contains shift-level plans across the period. Kaizen events ran between phases to identify and codify improvements before standardization.
The Kiva integration deserves a specific call-out. Amazon's robotic stowing system (Kiva pods) required dedicated shift planning and headcount mastering. The Kiva Sort IB Shift Planner went through 3 versions during the tenure, integrating Kiva-pod throughput targets with traditional manual stow stations.
What the Role Produced
265 to 290 units per hour. Driven by Team Leader pipeline and Standard Work standardization.
9 to Tier 3, 2 to L4. The Team Leader pipeline produced demonstrable upward mobility.
Including coverage during leadership vacancies across multiple teams.
Month over month improvement during tenure.
The Pattern Behind the Result
Operations Manager work at Amazon scale combines two disciplines that rarely show up together. The first is daily execution under pressure with hourly targets, headcount churn, and quality gates that cannot slip. The second is the standardization layer that lets execution survive the next leadership rotation. The Standard Work, the Task Lists v1 to v3, the Open Stations Master, the IOL Wash Templates. The artifacts make the role outlast the person.
This is the same pattern that produced the AM/VM Responsibility Matrix v4 at Brand Concierge, the PEAK Operating Framework at Amazon Ads, and the three-phase WFM operating model. Diagnose, document, deploy, iterate, hand off.
