D473 Task 1 — Original Practice Analysis
Northstar Sealants synthetic example • 2026 rubric-architecture study aid • Not an official submission
Workbook section Purpose
Identifies one service-problem variable and supports it with quantitative
A1_Service
evidence
Identifies two distinct cost-problem variables and supports each with
A2_Cost
quantitative evidence
Maps root causes to immediate process effects and business impacts for all
A3_Cause_Effect
three variables
Source Data Contains the 24-month synthetic dataset and transparent formulas
Assumptions Stores all management targets used in the analysis
Rubric Map Connects A1–A3 and B1a–B3b to the practice artifacts
,Academic-use notice
This workbook is a fully worked practice model using a different fictional organization and
synthetic data. It demonstrates analytical technique and rubric organization only. It must not be
represented as Endothon data, an official WGU answer, or an evaluator-confirmed passed
submission.
, Analysis Assumptions
Editable targets are centralized here so every calculation is traceable.
Assumption Value Unit
OTD target 95.0% %
Freight cost per unit target $6.00 $/unit
Annualized carrying-cost target 20.0% %
