Lead times (created to done) and cycle times (in progress to done) are the flow management tools used with a kanban practice. We mostly use these for Goal and Initiative records. Currently creating list report and export for charting in excel.
Thank you for your idea. This is currently possible using calculated columns. Within a list report you can create the calculated column to calculate the difference between the completion date and created date (or start date.) You can then switch the report type to a pivot or chart for additional visualization options.
This support article provides more details on how to use calculated columns.
Measure cycle and lead time in Aha! Develop
Agile development teams can now measure cycle and lead time in Aha! Develop — so you can set delivery expectations with confidence.
However there is no way (to my knowledge as I have asked Aha! Support) to show TRENDING of lead time and cycle time over time. This is a health metric critical to lean agile / kanban. This is the use case they are probably exporting to Excel or another tool to produce, as I am doing.
