You can record and track the pure time you have spent on a given task or a subtask by manually logging time. Tracking time is useful for billing purposes and for future estimates and planning.
To log working hours against a card/subtask, just right-click on the card itself to open the context menu and select "Log time". You can log time against the card or any of its subtasks on as many separate occasions as it is required based on your work item.
To learn how to log time, please check out the dedicated article.
Businessmap tracks the working hours logged by users. When you want to review the logged time you can use any of the following methods:
The Card Metrics Tab

The Advanced Search tool
Using the Advanced search tool you can create filters and get tasks with logged time per board, user, etc.
Open the short video below in a new tab to get a closer view of the most common search scenario* for cards with logged time. Note that you can refine and configure your search according to your use case. For example, you can filter cards by Type and the system will generate a report for cards with a logged time of a certain type only.
* The video below filters all cards on a certain board and provides an overview of those which have been logged time. Then, using the refine search criteria, you can filter by an Owner to further narrow down your search.
The Worklog Reports
To generate Log time reports on a global level, you can use the Worklog report tool from the top right of the menu.
The Worklog report tool can generate a report with the time logged per each of the users for each workitem, for a given period of time. Moreover, the tool allows you to get data for a selected workspace/board/columns and lanes. On top of that, you can also export all the data from the report in a CSV format.
