Can you help me to answer discussion questions in the case study below in details? Thank you very much.

CASE APPLICATION 1 It's estimated that the average corporate user sends and receives some 112 e-mails daily.73 That's about 14 e-mails per hour and, even if half of those don't require a lot of time and concentration, that level of e-mail volume can be stressful and lead to unproductive time. Once imagined to be a time-saver, has the inbox become a burden? Back in 2007, US. Cellular's executive vice president, Jay Ellison (who has since retired), implemented a ban on e-mail every Friday. In his memo announcing the change to employees, he told them to get out and meet the people they work with rather than sending an e-mail. That directive went over with a thud. One employee confronted him saying that Ellison didn't understand how much work had to get done and how much easier it was when using e-mail. Eventually, however, employees were won over. Forced to use the phone, one employee learned that a coworker he thought was across the country was, instead, across the hall. Now, in 2012, other executives are discovering the benets of banning e-mail. Jessica Rovello, cofounder and president of Arkadium, which develops games, has described e-mail as \"a form of business attention-decit disorder.\" She found her- selfand her employeesputting e-mail in the inbox ahead of everything else being worked on. What she decided to do was only check her e-mail four times a day and to turn off her e-mail notification. Another executive, Tim Fry of Weber Shandwick, a global public relations firm, spent a year preparing to \"wean\" his employees off their e-mail system. His goal: dramatically reduce how much e-mail employees send and receive. His approach started with the firm's interoice communication system, which became an internal social network, with elements of Facebook, work group collab- oration software, and an employee bulletin board. And then there's Thierry Breton, head of Europe's largest IT firm, Atos. He announced a \"zero e-mail policy\" to be replaced with a service more like Facebook and Twitter combined. 0 DISCUSSION QUESTIONS 14-13. What do you think of this?
