So I previously showed how I used a taskboard at home. Just to give you another example I wanted to show you what I did last week to keep track of the customer issues I was working with together with the customer.

Status Board 

I guess the "who" and "what" fields are pretty easy to understand. The last three columns I used to track the status. A magnet in the "wait" column meant I  was waiting for customer feedback on some question I asked them. "Work" meant I could work on the issue in some way. At a minimum ask a new question. The "WI/D" column was used to track work item number (WI) and once issue was resolved it was "D" as in done.
