It's easy for teams to forget to work on a specific item. This visual makes the forgotten items easy to see
Having decided the states which we want track work across select them from all the states across your board (1). It's easy to see the items that have been there the longest - shown in days up the Y axis. User stories and bugs are shown in different colours.
The red line (2) shows the average time that items have spent in that state in the last 30 days.
Click on a column (1) to see details on the item and then open it (2) directly in TFS
