Slack is well suited for quick communication. I appreciate that people don't crowd my email with items that can be handled in a quick response. It's also great for sharing links and such with others. You can also communicate without words. Emojis work just fine. It helps avoid an influx of noise. Slack is not at all well suited in situations where you need to list many things. I find the bullet function not easy to use.

Pros
Chatter
- Chatter provides us with a live internal conversation for all to see without the noise that other mediums have i.e. e-mail.
- One of the main features that really works well is the 'Groups' that you can join. We have multiple groups set up to not only distribute procedural changes and communicate news etc, but also have conversations around upcoming tasks in the months ahead.
- Chatter works really well in instances where we need to look over historical conversations that have been had and the sentiment of those conversations with our shareholders, often using hashtags.

Slack
- Communication with members of a project ( via channels features where you can create specific dedicated groups for project members only)
- Third-party app integration ( Integration with Asana, Gmail, JIRA, GIFy, etc.)
- Daily Huddles - This has been one of the latest addition to the features, and this has been liked by all of our team members. It makes running daily huddles super easy, considering the WFH environment that we are in.

Chatter
- Groups does not have the private messaging functionality. Since most collaboration takes place in Groups, private messaging would allow for relevant conversations to be contained and not reside separately.
- On a Group index page, there are two boxes for Information and Description. These content types seem redundant. You could replace both with a content type called About the Group. There could also be another box listing the Owners for quick reference.
- On the main index page, the newsfeed has the same look and feel of most social platforms like Facebook, LinkedIn, Jive, IBM Connections, SharePoint. There could be an alternate display of tiles that shows People you interact with most frequently, Files you access most often, most recent Topics, etc. The display could be something like Delve in Microsoft Office 365.
- On the main index page in the right rail, it would be useful to have the ability to incorporate RSS feeds to gather outside content. Many departments heavily leverage RSS feeds to compile competitive intelligence and cultivate general awareness.
- For user profiles, can we combine Feed and Overview into one consolidated view? It would save users a click to find relevant information about the person. Also, the Contact module should also have the person's phone number for convenience.
- The Files feature does not allow for real-time, concurrent document editing. You have to download the document, make your edits, save, and then upload a new version, which only allows for one editor at a time.

Slack
- You can have a voice call with you team. But, it's better to have a video call function.
- Sometimes it's hard to find the direct message in threads.
- When opening the software and app. The refresh rate after logging in is slow.
- If you manage 2 businesses. You can't manage them in one platform because you need to create a separate Slack link for it.

Chatter can fulfill at least 85-90% of our business requirements in an easy-to-use platform. Usability is a key requirement and we have had our share of bad usability experiences. In our experience, even the most novice users were able to pick up Chatter in a relatively short amount of time with little/no assistance.

As useful as Slack has become within our company, I feel fairly confident we will continue to use Slack as a communication tool. They continue to improve their software and add value to its use within our office. Customer service delivers, which is an absolute must. Looking forward to how they improve.

It is easy to use but the impact of it feels like it is a bit antiquated. It does not feel collaborative and real time. Chatter is more akin to email versus Slack or Hangouts where it feels like problems are being solved as you are communicating.

As long as you use the basic chat features and nothing more, it really is super easy to understand and use. Once you want to take advantage of some of the more advanced features and capabilities, that's when things get complicated. Anyone who has use SMS or a chat program before will be able to figure out the basics though, so rolling this out should be relatively straightforward and not required exhaustive training. Teaching chat etiquette is something else though.

If I ever came to a situation where i needed help they do a very good job of getting back to us quickly to explain our error or why we are not seeing something. The support is quick to help provide groups or teams if you seek. Fortunately it is user friendly so I rarely need support

I've never had to contact support for Slack which is a great testament to its ease and use. Adding people outside of the organization takes a little getting used to, but ultimately allows for greater collaboration between FTE and contractors. There is no clear alternative to this software, so it's the best we can do for now.

It always helps if you communicate to everyone in the organization how important it is to drop whatever other chat tools they are using and jump quickly to Slack. They will all fall in love with it.

Chatter
Skype is used more for audio calls. Chatter is used to track updates on items of interest in Salesforce. Chatter is deeply integrated with other Salesforce products. No other competing products come close. Slack is a traditional project management tool. So it does not compete with Chatter. Because of its close integration with Salesforce, it is a unique tool for Salesforce users.

Slack has expanded functions and much better connection. Slack is heavily customizable whereas 3CX and Google Chat are standard across the board. To my knowledge 3CX and Google Chat do not have the thread function, expanded reactions function, group channels vs group messages, profile photos/titles for users, or customized viewing preferences

Chatter
- Chatter has closed deals faster, and brought us in revenue at a quicker rate in turn.
- Chatter has left some things undone simply because people didn't see it and it has cost us a few deals.
- Overall, Chatter has brought us a cleaner, more efficient Salesforce process and brought in revenue because of organization.

- Positive -> Easier collaboration as and when required with the ease of use of the tool.
- Negative -> Too much communication (partly because of the ease of use) which might result in introducing a lack of structure and makeing it overly informal.
