About this ranking

What this page ranks

This page ranks 7 of the 22 assessed business consulting agencies in New South Wales, Australia — the ones carrying a published score — out of 27 listed.

The score measures how well an agency documents its own work in public — named clients, quantified outcomes, and whether those outcomes are attributed to the agency rather than described as the client's own results. It does not measure client satisfaction, price, or availability.

Cohorts and awards

Agencies are compared within a cohort — here, Business Consulting in New South Wales, Australia. A cohort must be large enough to express the band being awarded: at least 8 assessed agencies for a top 25% award, 20 for top 10%, 40 for top 5%, and 300 for top 1%. This one holds 22, so the strongest award available here is top 10%.

The 6 business consulting agencies not yet assessed are listed on this page but not ranked.

A further 15 were assessed and no published evidence of their work was found, so no score is shown for them.
