Atlassian ConfluenceSlack
Considered Both Products
Confluence
Chose Atlassian Confluence
Atlassian Confluence is more intuitive than MS SharePoint, however, SharePoint has some reach features because of the MS integration with its tools stack.
Chose Atlassian Confluence
Confluence smashes competitors out of the ballpark. There is no compromise for quality and great product design with Atlassian
Chose Atlassian Confluence
Atlassian Confluence is better than all Google Drive, Dropbox as we can just store files in them without specific versioning, but with Atlassian Confluence file is stored in versions.
It is easily integrated with other softwares like Jira so one can keep track on all the …
Chose Atlassian Confluence
It's quite famous and consistency and alignment are what we're after with using Confluence and all of Atlassian's products. This has helped us to be more transparent with out product and development teams as well.
Chose Atlassian Confluence
There are complementary and we are in fact using both of them in out organisation. We are using Google Drive for advanced real-time cooperation when creating documents, since Google Drive can handle this in a more streamlined and easier way than Confluence. Still, Confluence …
Chose Atlassian Confluence
I think the only comparable product is Google docs. Google docs is a much simpler product, however, it doesn't have all of the features that confluence has. I think if confluence improved their UI to make it a little better, it can really improve.
Chose Atlassian Confluence
I have used other tools that allow for documentation and housing of other business-related documents but none that I used had the same integration or general ability to add and edit information. I am also a general user so I don't know how easy/difficult the backend is, but …
Chose Atlassian Confluence
To keep the user stories together, we used the Microsoft Office tools. It took a lot of time to search for the relevant stories, so we moved to Atlassian Confluence which is now saving a lot of time.
Chose Atlassian Confluence
SharePoint is great, I use it and I love it. Confluence is a lot like SharePoint with a more modern look and a fancy suit. If you have the skills for implementation, it is great and developers will enjoy it more.
Chose Atlassian Confluence
Although similar in the way in which they can be used, Atlassian provides great archival and search features, as well as editing capabilities that set it apart. Security through 2-step verification is an important feature often overlooked, being tested now in beta. Overall it …
Chose Atlassian Confluence
With this tool, everyone is in the same place. You and your teams will have the information that is usually lost in email inboxes as well as shared network drives. Data become much easier to find, use, and update with Atlassian Confluence.
Chose Atlassian Confluence
For our needs, Confluence absolutely blew both SharePoint and Google Docs out of the water. We were able to get more granular security than with SharePoint while maintaining the collaborative tool sets found in both SharePoint and Google Docs. Additionally, the integration into …
Chose Atlassian Confluence
The Knowledge Base was something we created. We found Confluence to be a superior tool. The fact that Atlassian is constantly working to make it better continues to be a bonus.
Chose Atlassian Confluence
We really only use Confluence because we use JIRA and Hipchat and it seemed to work well within the suite of Atlassian products. I would personally prefer a custom made internal website for our organization plus the integration of google docs/hangouts (or the use of something …
Chose Atlassian Confluence
So much better, in many ways. You can use it for many differents options. Trello is more just a scrum board, but Confluence is for the whole communication process. It's super organized and very trackable. It has helped the tech team to be very connected! They love it, and we …
Chose Atlassian Confluence
Confluence is much easier to use, it's philosophy is more modern because of social, and it's a by far lower investment (better value for money).
Slack
Chose Slack
While teams is better for conference calls and telephony, Slack surpasses it with it's ease of use, integration possibilities and search capabilities. Having one place where all your collaboration takes place, together with notifications and alerts from all other portals is …
Chose Slack
Slack is much more modern and sleek compared to both Webex Chat and Microsoft Teams. Slack is specific for what the purpose is, and it doesn't over engineer too many other features.
Chose Slack
I think Slack is very straight to the point and a tool you can't live without. It is where you find light, info, share and build results as a team player.
Chose Slack
- MS teams Vs Slack - Slack athread View is incredible - API integration helps with our product - Multiple Domains Login is seemless - Google Chat Vs Slack - google is too messy. Great for chatting and productivity as individual tools. But as integrated productivity …
Chose Slack
Provides the huddle feature, sending attachments and get integrated with the meetings scheduled.
Chose Slack
I would say slack outperforms Microsoft Teams in many areas. The big one would be ease of use and user interface. I strongly prefer Slack's interface and the ease to switch between conversations and calls very quickly. Slack also seems to run a lot better on Mac computers, …
Chose Slack
Easy to setup and use compared to other similar products.

Screen sharing makes the discussions a lot more effective.
Chose Slack
Slack is more user-friendly than Microsoft Teams, at least in my opinion. Microsoft Teams integrates natively with Office 365 tools. Microsoft Teams has a limit of five users on paid plans unless you buy more licenses, whereas Slack allows unlimited external collaboration with …
Chose Slack
We used Spark Instant Messenger before and Slack blew them out the water with a wealth of features we hadn't used before. We didn't need to be on the VPN to communicate and we could do video calls and make our own groups. Everything was better with Slack, as it kind of merges …
Chose Slack
We felt Slack [had] more community friendly tools to share thoughts and an individual view to achieve better and bigger goals. It is also easier to browse and search compared to our previous HipChat tools. It encourages more IT people to get involved in ongoing discussions.
Chose Slack
Having had to use Skype/Lync in a former life as a Fortune 100 contractor, I can say that Slack's ease-of-use, customizability, and solid integrations with online tools puts it far ahead. It's nice to not be beholden to the Microsoft Stack for every little thing, as well. …
Chose Slack
Slack blows Skype out of the water. It is a new, quicker and more efficient instant messaging tool. The capabilities are continuously being updated and can be configured to protect your organization. Slack emojis bring color to your messages and help you feel closer to the …
Chose Slack
Slack is a bit more simplistic than the other pieces of software, but creates more meaningful conversations. The other programs create more of a forum based platform, than a social network like Slack. Slack encourages everyone to get involved with the conversation as opposed to …
Chose Slack
Slack is definitely the marketplace leader for chat / digital communication. Overall Slack has done a very good job of making communication and collaboration easy and non-disruptive. The biggest feature that sets Slack apart from the other tools is the clean interface and …

It has a comment option on the page, where you can tag other teammates tagging them. it sends the mail notification. Comment at the page end is pretty good for referring to other stakeholders and future references of the topic on the page. Creating the highlights of the discussions, and meeting held points with highlighted tagging. Easy shortcuts such as to add a date just type "//". The interface is cool and has easy shortcuts for quick page making.

I think Slack works really well in office settings, or even for any group of people who need an easy way to communicate with each other through organized channels. It may not be the best for those who intend to use it as a social media type app, it is more geared towards business use.

  • Automated Notifications: Integrated tools like Jira, Trello, and Google Drive to receive automated notifications and updates directly in Slack, improving visibility and efficiency within the team
  • Message Encryption: Slack encrypts the messages in transit and at rest, ensuring the security and privacy of sensitive information and making our IT team's life much easier.
  • Reminder Bots: We used Slackbot to set reminders, automate follow-up actions, and provided information based on user queries.
  • SurveyMonkey Integration: Integrated our Slack with SurveyMonkey to distribute surveys and collect feedback from team members, streamlining the feedback-gathering process which was a huge support to our HR and Admin team.

Cons
Atlassian
  • Navigation. Similar to other Atlassian products, users have complained that aspects of Confluence are difficult to learn right away[.]
  • An issue that users can face when using Confluence is attempting to edit a document while someone else is editing. Although users can access the document and save it, they are unable to see the changes happening in [real-time] that other users are implementing until they refresh their page. Some users have also noted that this can result in loss of edits.
  • Another drawback of using Confluence is its specific organizational structure. All information is stored within one page or project, although the page is able to be broken up into sections, some users do not prefer this style. Users can use the ‘page tree’ on each page to organize the different elements of each project.

  • The only thing I can think of is that it is easy to create too many channels. This has more to do with the team using Slack and less to do with Slack itself. maybe some direction on Slack's part on how best to utilize channels would be helpful.

I am confident that Atlassian can come with additional and innovative macros and functions to add value to Confluence. In 6 months, Atlassian transformed a good collaborative tools into a more comprehensive system that can help manage projects and processes, as well as "talk" with other Atlassian products like Jira. We are in fact learning more about Jira to evaluate a possible fit to complement our tool box.

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.

Usability
Atlassian
Confluence can - and in my personal opinion, it will - be a bit hard to use in the first moment. Atlassian is a great company and is eager to help you with any question you have, though. The interface seems to be a bit clumsy at first but the customization options are enough to make it easier and simpler. In general, Confluence is easy to use when you understand what each section does, but this can take a while.

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.

Pages load very quickly, which makes it useful for quickly obtaining information. The search functionality is also very quick and is able to parse through all of the documents to provide the most relevant results for the query. Other information based software gets bogged down, but so far Atlassian Confluence maintains its performance.

Atlassian
This rating is specifically for Atlassian's self-help documentation on their website. Often times, it is not robust enough to cover a complex usage of one of their features. Frequently, you can find an answer on the web, but not from Atlassian. Instead, it is usually at a power user group elsewhere on the net.

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.

We used to use Google Drive to store all of our documentation, but it is disconnected from our every day working environment and it was easy to lose documents and become disorganized within the broad drive environment. [Atlassian] Confluence has kept us more organized and its tight coupling with Jira has made documents more accessible and more likely to be kept up to date.

Return on Investment
Atlassian
  • We've gone from folders and folders of Word documents and PDFs into a single system with a search feature to bring all of our data together and trackable
  • While onboarding took a bit longer for the company (to switch from a Word document centric mindset - to a web-based one), overall the company has embraced the features and power of Confluence within the working stack
  • However, as costs continue to climb for the Atlassian product, we are forced to continue our evaluation of the product - with replacing it a remote possibility if it begins to outprice its usefulness to us.
