Jon Husband points out that while the organizational chart may remain the same, the way people are working has changed dramatically over the past 15 years.
The organization in which you work has probably involved everyone in using computers for at least 15 years now. People sit behind laptop or desktop screens, and increasingly are on the move or working remotely, using laptops, tablets and smartphones. Web access is growing in ubiquity, and access speeds are increasing. The people in the organization are interconnected and exchange information with each other all day long.
