DBA PRO CORP

Services

Sherwin Shao is the principal consultant at DBA PRO CORP. He is referred to as the “Inventory Guy” at his
client organizations, as he helps focus on improving inventory operations.

Background

The techniques he developed for inventory management were motivated by the difficulties he faced when he
owned physical retail stores. “Selling supplements retail was a very competitive environment”, Shao says. “The
intense margin pressure left no room for operational mistakes.
When asked about systems support for his operations, Shao said, “The existing systems did not help optimize
our operations. Inventory On Hand is a static number, but I wanted context on how long that inventory will last.
Sales reports were all based on time ranges such as months, which is a rough measure that ignores real-time
information.

Retail Science

Shao continues:  “So we built our own system, leveraging best practices in finance and engineering. We simply inverted the bucketing concept, and came up with a new Speed metric representing the number of days between sales for each UPC.”

“Here’s the problem we’re solving. If your report shows you sold 25 items last month, you may order 25 more to restock. What if all the sales were in the first week, and inventory on shelf did not move in the last 3 weeks?”

“So imagine items flying off the shelf every 2 days regularly.  In that case 30 items in inventory should last 60 days.  Now imagine 3 days pass before the next sale, then 4 days pass, instead of the regular 2 days. It’s clearly slowing. Traditional reports using time range buckets will show nothing until two months later. Using dynamic data from Retail Science, you can be alerted to the change in speed immediately, and respond quickly.”
