From the Ask Tom mailbag:

Question:

I have been reading the section of your website on Time Span and I am curious. How do you measure objectives in terms of Time Span?

Response:

Time Span is a concept I have been working with since 2001. It is based on the research of Elliott Jaques (1917-2003). Time Span is most useful as a measuring stick to determine the complexity of any task. The longer the Time Span of the task, the more complex the task is likely to be.

Attaching a Time Span to an objective is extremely helpful in understanding the breadth and scope of the objective. For example:

Objective – As the department manager, hire a person to fill the vacant position on the team.

In the short term, if the Time Span is described as two weeks, then you can imagine that the tasks involved would include posting an ad, reviewing resumes, conducting some interviews and making a selection.

However, if the Time Span is described as six months, you might imagine a much broader scope for this project. The tasks would extend to bringing that person on board, moving them through the training process and evaluating their initial skill level. This might be followed by supervising additional training and re-evaluating their skill level. Once on the production floor, the manager would select appropriate assignments for this new recruit, then advance them to more complex tasks as time passes. After six months, it might be expected that this new person now possesses the skills and competence to fill the position as a productive member of the team.

Taking this one step further, if the Time Span is described as 12 months, you would imagine an even broader scope. The tasks would extend to evaluating proper staffing levels to determine, if indeed, this vacant position needs filling in the first place.

Time Span, as a unit of measure, helps us understand the breadth and scope of the task, and ultimately the scope of the role. -TF
