Hi @Liam_Higton-Shirt, welcome to the Asana Community Forum!
We currently don’t offer a Performance Dashboard for each team member. However, you can create reports of tasks completed on Time and Overdue tasks using the Advanced Search feature. You can then export your report and see “Due date” vs “Completion Date”.
We also have a couple of threads with more tips from other community members, you can join the conversation here:
- Reporting “On Time” Completion of Tasks
- Can is see “Completed time stamp” in search result or report?
- Overdue Tasks Reports
I hope this helps! Let me know if you have any other questions!
