Detailed Description of WOS Calculations

Lowe’s WOS - Current unit inventory / Last week’s unit sales (This is at whatever level the report is built - store, market, category, etc. Note this is also a very volatile metric, and is often misleading during the beginning and ending of each season as sales change.)

Store WOS is calculated using 2 factors:

  • The weekly sales rate you set in your User Preferences

  • The WOS target you set in each order template.

User Preference Weekly Sales Rate in units is the combination of these 2 parameters:

This creates a weekly sales rate for a single week (per store/item). This is then multiplied by the WOS setting you choose in your order template.

Market WOS is the value of the store inventory in units for all the stores in a market divided by the average POS for the market over X weeks (Ross getting X; need to know if this is adjustable or fixed.)

Blended WOS is the value of Store WOS + Market WOS / 2; (Rarely used except in special situations, which we should specify. Also, is the Store WOS the value of the inventory of all the stores in the market / the inventory of all these same stores?)

Effective WOS is the value of  your User Preferences Effective Inventory setting / the calculated one weekly sales rate (see first box above).

In using the WOS metrics we recommend the following order of importance in evaluating your inventory:

  • Effective WOS

  • Market WOS
