Timespan is a frame to understand.
Timespan is the language of context to understand what is happening now in relationship to the past and future. Anecdotal references to the “big picture” or “50,000 foot level” can specifically be measured in timespan.
We can look at business processes, over time, and examine the cause-effect relationships of process elements. We can also look inward, look at ourselves, over time, and examine the cause-effect relationships of our own internal decisions. What happened in the past shapes the present. What is happening now gives us insight into the future, but only if we can see the context.
Who are you now? Who will you be in one year? Who will you be in five years?
