Do I need to have a "Completed" column on my board?

While it's not necessary, there are two main reasons you may want to have a "Completed" column.

No, it is not necessary, it depends on personal preference and the needs of your team. There are two main reasons to have a "Completed" column:

1. If you want to review tickets that have been completed within a specific timeframe, such as the last day or week, then having a "Completed" column can be helpful.
2. If you want to provide a designated place for technicians or engineers to drag tickets to once they are done. 

If neither of these reasons align with your workflow, then you may not need a "completed" column on your board. Technicians can still mark tickets as completed or close, even if there is no column for it.
