This is very quick but helpful IMHO.
Scenario: you are an external consultant and you need to run a job from the Team Foundation Server web services (ProcessWarehouse, just to mention one of them), but you cannot access the server itself because of some security policy.
You ask someone in the IT department to run it on behalf of you, but of course you want to check how long does it take. How?
By using the TFS Operational Intelligence. If you check the Job Queue list, you will get all the running and scheduled jobs for the server.
If a job is running you will get the actual running time, otherwise the last execution’s time.
