The processes screen lists your processes and, for each process, the results bar for the last run of the process. If you hold your mouse pointer over a results bar, a results summary for that particular run will pop up.
This screen will also give you visibility to who last ran a process, with the exception of any processes ran using SFTP, in which case the column will be blank.
By default this screen will only display processes that you have some level of access to. However, if you uncheck Visible to me you will be able to see (although not access) all the processes.
