Examples of Span
For example, in construction, the span of a bridge is the distance between its supports. In communication, the span of control refers to the number of subordinates a manager can effectively supervise. In psychology, the span of attention is the amount of time a person can focus on a task.
Case Studies
Research has shown that individuals with a longer attention span tend to perform better in tasks that require sustained focus. Companies that have a larger span of control may experience challenges in communication and decision-making due to increased complexity.
Statistics on Span
A study found that the average attention span of a human has decreased from 12 seconds in 2000 to 8 seconds in 2020, possibly due to the rise of digital distractions. In business, organizations with a narrower span of control have been found to have higher levels of employee satisfaction and engagement.
