Supplier Ratings Data: Internal Travelers Share Travel managers have always listened to feedback, solicited or not. Some make it easier for travelers to share their experiences, recommendations and criticisms via internal social media sites. Others opt to build supplier-rating tools on internal company portals.Pros & Cons: Such efforts are in their infancy. Formal review tools may be bundled for sale with other tools but often require a budget to build and monitor such resources. Traveler participation can be inconsistent, which reduces value. Such tools enable travel managers to apply data on supplier quality to the procurement process and to address issues as they develop.Access/Format: Depends on the tool used. Informal social media stats may be fairly unstructured.
