Opening Case

Can Slack Really Replace E-mail?

E-mail has presented a productivity problem for employees for some time. Over 200 billion e-mail messages are sent and received every day. Employees receive some 122 e-mails per day. Dealing with those e-mails consumes 23 percent of the average employee’s work­ day. In response, an increasing number of organizations are finding that limiting, or even eliminating, e-mail actually increases employee productivity.

MIS

Slack ( www.slack.com ) may provide one answer to the prob­ lems with e-mail. Launched in 2013, Slack is a cloud-based team com­ munication and collaboration software program that helps company

employees communicate in real time. Slack allows different parts of a business to set up different channels for discussions. One channel might be for the information technology group, another for the mar­ keting group, and so on. Anytime someone wants to alert you about something, he or she tags your name to a message. You can follow your colleagues’ exchanges in real time, or you can return to that conversa­ tion later.

Slack offers many features, including chat rooms (called chan­ nels) organized by topic, private groups, and direct messaging. All content inside Slack is searchable, including files, comments, conver­ sations, and people. Channels enable team members to communi­ cate without the use of e-mail or texting. They are open to everyonePlease read these 4 chapters (chapter 6,7,8,9), and write a short reflection essay (least 2 pages) to reflect upon the learning experiences in these 4 chapters.
