Slack

It is especially valuable in helping with communcation between remote team members. The ability to call and share screens is really helpful, and has become our go to method to communicate, eliminating the need for skype and our various conference call systems available in our company. Using Slack for calls and meetings is now extensive within our group, and is done many, many times per day. it is easy to add people and to share and give sharing capabilities to other team members.

Cons

Slack

  • The sorting of channels - it's a bit confusing, could be better sorted, it would make it easier to search and make it more agile.
  • Search - It could also improve, it is not bad, but in some cases (rare) it is difficult to find the term that you want.
  • Heavy performance in other operating systems - At least in Linux, Slack seems to do a little more machine performance than when it is used on a computer running Windows.

Slack sitll lacks in functionality. It's better than Skype for Business in many ways, but it is still another chat/message board app. It has limits in free version and paid versions. Also Windows app has errors that bother me, for example, I see number on one of my team's icons. It suggests that one of channels has unread messages; I check all channels - no unread messages, but that "1" still appears

It's an amazing communication tool. It's like Slack took everything that made Skype amazing at the time, made it much lighter and tailored it to make it work in a business setting. I love that, even though Slack isn't a project management tool, it can help you manage and not stress the day-to-day stuff.

We haven't really had any issues with Slack -- so that's part of their support: Having a product that works perfectly out of the box and doesn't need additional setup/support.

Alternatives Considered

Slack

Slack is a more all-around complete platform than either Skype or Google Hangouts. Skype is better at video conferencing, but Slack is better for project management and archiving. Google Hangouts is simple and easy, but Slack offers way more features and is all very user-friendly. Slack can become the go-to service for all office communication and replace all other similar products.

Return on Investment

Slack

  • One of the metrics we have watched over the years is our average resolution time. Prior to two years ago when collaboration was accomplished via email, phone calls, or visiting offices within the department, our average resolution time was around 72hrs. Over the past year we have reduced that to around 48hrs.
  • While not quantifiable, the reduction in email noise has allowed our technicians to prioritize more effectively, and provide important information to colleagues in a timely manner. We know that these factors have improved overall service.
  • Prior to our use of Slack we typically had weekly staff meeting that ran 2-3 hours in length. Today we meet bi-monthly, or even once a month since Slack allows us to post updates on projects, and note outages/emergency issues that have appeared.
