Question:
That post was completely opaque. What did you mean by “the time span of the team member”? Experience, availability, something else?

If you don’t mind a piece of advice, when you’re blogging in the middle of the night, don’t post right away. Wait until the next morning so that you can reread and correct your post with a clear head. -GH

Response:
Time Span is a recurring theme in this blog. For those unfamiliar with the concept, you can access the Time Span Category on our site where we have 190 other posts about Time Span.

Time Span isn’t experience or availability. Time Span refers to a team member’s capability and is based on the research of Elliott Jaques. Elliott discovered that each person is born with an ability to handle a certain amount of complexity in their world. This ability (capability) is measurable. The metric is Time Span.

Time Span is the length of time that a person can work into the future, without direction, using their own discretionary judgment to achieve a specific goal. It is an objective measure of capability and a cornerstone for delegation.
