Every case study in this ranking passed the same checks: the page is on the vendor's own domain, it describes testing work, it names a logistics system or client, and every quoted figure is on the page. You can run the same checks in a few minutes.
The checks
- Domain: the case study URL is on the vendor's own domain. Listings on directories do not count.
- Testing work: the text describes testing activities, test types or a testing outcome. A team list with one QA role is not enough.
- Logistics: the text names a system (WMS, TMS, fleet, last-mile, freight, EDI) or a logistics client such as a 3PL, carrier or courier.
- Client: the client is named in the text, not only shown as a logo.
- Figures: each outcome has a number and a unit; note the period it covers.
- Date: a visible date or a date in the page metadata. Undated pages lose one grade here.
