A Warehouse Charter That Blames the Process and Misses the Customer
Northline Distribution's main warehouse ships about 9,000 orders per month. The VP of Operations chartered a project to reduce late shipments from 14% to 3% within six months. The charter lists the team as the warehouse supervisor, a picking lead, and a Black Belt; it excludes IT, carrier management, and customer service. The problem statement says warehouse picks are slow and inaccurate and the goal says improve on-time shipping. Customer complaint logs from the last quarter were sorted into 180 entries: 72 about missed delivery dates, 41 about wrong items, 33 about damaged goods, 22 about poor communication, and 12 about invoicing. The sponsor wants the project to cover all five regional warehouses because the same problem exists everywhere. The Black Belt has two weeks to complete Define and present at the tollgate.
1. Critique the charter's problem statement, goal, scope, and team. Rewrite the problem and goal so they are measurable and bounded.

The problem statement is solution-blamed and unmeasured: it names picking as the cause before any data analysis, and it says slow and inaccurate without a baseline, location, or customer effect. The goal says improve on-time shipping, which is not a metric, target, or deadline. Scope covering all five warehouses conflicts with a six-month goal and one team; it also prevents the team from diagnosing local causes. The team excludes IT, carrier management, and customer service, yet the complaint Pareto includes missed delivery dates, communication, and invoicing, which sit outside warehouse picking. A better problem statement: From January through March, 14% of the 9,000 monthly orders at the Northline main warehouse shipped after the promised ship date, versus a customer requirement of 3% or less. Goal: reduce orders shipped after the promised ship date at the main warehouse to 3% or less by December 31, without increasing damage or cost per order. Scope: order release through carrier pickup at the main warehouse. Exclude carrier transit performance, invoicing, and the other four warehouses in this phase, with a follow-on replication plan. The team should add IT for system timestamps, carrier management for pickup and transit data, and customer service for complaint definitions.
2. Identify the missing stakeholders and SIPOC gaps, and explain how each missing voice could bias the CTQ definition.

Missing stakeholders include the customer service team that receives complaints, carrier management and carriers that control pickup and transit, IT that owns warehouse and order timestamps, and Finance or billing for invoice accuracy. Without customer service, the team may define on-time as ship-date compliance while customers judge on delivery-date compliance; the 72 missed-delivery complaints could be caused by late shipment or by carrier transit, and the team would misdirect the project. Without carrier management, pickup delays and transit variability are invisible, so a warehouse fix may not move the customer metric. Without IT, timestamp definitions, time zones, and order release rules remain ambiguous, making the CTQ unstable. Without Finance, invoicing complaints appear out of scope even though they affect overall customer satisfaction. SIPOC gaps: suppliers include carriers and the order-entry system; inputs include order release time, pick confirmation, packing quality, and carrier pickup; process steps include release, pick, pack, stage, and load; outputs include ship-date compliance, order accuracy, damage rate, and notification; customers include the retailer and its receiving dock. Each gap should be resolved before CTQs are finalized.
3. Translate the voice of the customer into CTQs with operational definitions and data sources. Distinguish which complaints are in scope for this project and which are not.

The 180 complaints are not one metric. Missed delivery dates, 72 entries, may be a ship-date failure or a carrier transit failure; operational definition: order handed to carrier after the promised ship date, measured from the WMS ship confirmation timestamp. Wrong items, 41 entries, map to order accuracy: line-item quantity and SKU match the order at pack verification and at customer receipt. Damaged goods, 33 entries, map to damage rate: units received damaged divided by units shipped, from claims and receiving audits. Poor communication, 22 entries, map to proactive notification: customer notified of a delay before the promised delivery date, measured from notification logs. Invoicing, 12 entries, maps to invoice accuracy but is outside warehouse scope; it should be routed to Finance. The primary CTQ is ship-date compliance, with order accuracy and damage as secondary CTQs because they are within the order-to-ship process. Each CTQ needs a data source, owner, and sampling plan; complaint counts alone are biased by reporting behavior and should be validated against transaction data.
