Course Overview

What this course is designed to develop

Most product owners learn inventory the painful way: they stock out of their best seller during a rush, then drown in dead stock that froze their cash. This course replaces that guesswork with a small set of reliable methods used across retail and operations: ABC analysis to focus effort, reorder points and safety stock to time replenishment, SKU rationalization to cut the long tail, and simple, defensible demand forecasting you can run in a spreadsheet. By the end you can decide what to stock, how much, and when to reorder, with the numbers to back every call.

Learning Outcomes

What the learner should be able to understand, build, or execute.

Calculate reorder points from demand, lead time, and a deliberate safety buffer

Size safety stock against demand and lead-time variability instead of guessing

Run an ABC analysis to focus management on the SKUs that drive revenue

Rationalize your SKU list by cutting unprofitable and dead inventory

Build a basic demand forecast using moving averages and exponential smoothing

Measure inventory health with turnover, days of supply, and fill rate
