On-shelf availability (OSA)

OSA (On-shelf availability) is a quantitative measure of the assortment matrix fulfillment at a point of sale. OSA is measured in percentage points, and ranges from 0 to 100, where:

  • 0% — not a single product from the matrix is on the shelf;
  • 100% — all products from the matrix are on the shelf.

Assortment matrix is a list of products that should be on the shelf. Matrices are set in relation to points of sale. Several different assortment matrices can be linked to each outlet at the same time. For each of them, its own OSA will be calculated.

A group of interchangeable goods — one or more SKUs, where each SKU can be counted instead of any other one for the purpose of calculating OSA.

Example

The matrix consists of one productAand there is an itemBon the shelf. If goodsAandBare interchangeable, then OSA = 100%.

As a rule, groups of interchangeable goods for OSA calculation are specified:

  • for a specific matrix;
  • globally per project.

How OSA is calculated

When calculating the numerator, groups of interchangeable goods are taken into account. Depending on the places of sale, OSA formulas are divided into:

  • OSA at the main place of sale (on shelf) — the numerator of the formula takes into account the goods that are presented in the main place of sale.
  • OSA in the store (in store) — the numerator of the formula takes into account the goods that are presented at any place of sale in the store (main, additional, at checkout, etc.).

In addition to these two main options, variations can be used. For instance:

  • OSA at checkout — only goods at checkout points are taken into account;
  • OSA at additional place of sale — only goods at additional points of sale.

Reasons for Out of Stock situations (OOS)

If there is no product from the matrix on the shelf, you can indicate the reason for its absence in the mobile application.

Notes

The list of reasons is configured individually for the project, and may differ in different tasks of the visit (categories, points of sale, etc.).

The statistics of the reasons for the absence of goods, in different views, can be found in the BI dashboard.

OOS Reason check workflow

Some responses to OOS causes may have the option to take a photo confirmation. For example, a photo confirmation of a “Recognition Error” is a photo of an unrecognized item, such a photo is called a photoproof.

The following algorithm is run to process the photo confirmation:

  • Sending photo confirmation to the server
  • Sending to IR for recognition (algorithms there recognize SKUs on the photo confirmation)
  • Recognition results are sent back to the server and saved
  • If the recognized photo has the desired item, then OOS is confirmed, SKU is updated and OSA is recalculated.
  • If the recognized photo does not contain the desired product, OOS will not be confirmed (SKU is not recognized on the photo).

In case the SKU on the photoproof is not recognized, there are 2 possible options:

  1. Accounting of any photo spring automatically (regardless of whether it has a recognized SKU or not).
  2. Manual re-recognition of SKU (with further recalculation of OSA).
