Supplier concentration dashboard

What does the supplier concentration dashboard produce?

Aggregate your nonnegative volume measure by exact supplier ID. Calculate supplier shares, top-N concentration, HHI and the effective supplier count using exact decimal operands.

The working area above runs the supported record workspace in the browser. It keeps the result inspectable and preserves every unresolved item for responsible review.

What do you need before you start?

• A named owner has defined the task and the organization’s intended use.
• The customer has authority to use every supplied record, source or connection.
• Prepare the result in this browser and resolve visible input errors before exporting.

What information do you enter?

Prepare only the bounded inputs listed below for this record workspace.

• Approved measure, population and period (required). Identify the complete supplier population, reporting period, volume measure, exclusions and responsible reviewer. The source must use one nonnegative measure.
• Common currency or volume unit (required). Each source row must use this exact unit. No currency or unit conversion occurs.
• Number of suppliers in the top-N share (required). Whole number from 1 through 5000. The calculation uses the smaller of this number and the actual supplier count. Equal-volume ties use exact supplier ID order.
• Independent expected population total (optional). Optional plain nonnegative decimal with up to six places. A mismatch with the source total withholds shares and HHI. Leaving this blank cannot establish population completeness.

What you can download
