If you have logged into LinkedIn in the past few months, you may have noticed a new function called Endorsements. This allow users to certify other members of their LinkedIn network in a particular skill or industry. If I’ve worked with Bob on a project and he’s proven to have strong SAP Materials Management skills, I can “endorse” him in SAP-MM. Other users viewing Bob’s profile can see this endorsement alongside all the other endorsements he has received. On each profile, you can now see a pseudo-barchart ranking that user’s endorsed skills. But of what value is this feature?
