Average Time to Complete -- Reporting

I saw this topic regarding dashboards, but not for the reporting function. I was messing around with some reporting metrics and stumbled upon “Average Time to Complete” a task as shown through projects (see below)

This one chart is great for reporting to upper management and also super humbling for a project manager such as myself :face_with_open_eyes_and_hand_over_mouth:

I am having trouble seeing value in such a metric since all tasks and projects have really various sizes, isn’t it?

It depends on how you utilize your portfolios really. This was just a general portfolio of ours, but if you break it down to be more specific it becomes more valuable
