There are a few different ways in which to track individual productivity within Kanban Tool.
The easiest one is to simply review the Done column, while possibly having the board filtered by assignments.
A more systematic approach to productivity tracking would base on the automatically generated metrics, which build up as work is being done on a board.
The Breakdown Chart can show current workload per person or per type, the Time Report gives the amount of time worked on tasks per each person, Lead and Cycle Time presents the time tasks spent in each stage, and Cumulative Flow visualises all work completed over time.
Furthermore, a lot can be read from the boards themselves, using global search functionality - with it, you can locate tasks related to virtually any given parameter.
Using the same search syntax, it is also possible to generate own, custom reports, and have them sent to specific users via Process Automation.
Also, let’s not forget the My Work part of Time Tracking. My Work is designed specifically for individual productivity. All tasks assigned to you across all boards get listed here and can be sorted, activated, timed, and worked on directly from it.
Do keep in mind, that you can also review and update your work progress from a smartphone, wherever you are, via a mobile app.
