Editing features improve document accessibility
There is a holiday calendar, however, I need to install an app or add something to it. The add-on feature is not readily available or well-documented. Guidance on this should be available in a forum. Recently, I used a feature in another tool—perhaps GitHub—where it helped prepare a chart. It involved listing resources, like having fifteen people in the X team, ten in the Y team, and seven in the Z team. It created a bar chart showing these numbers. This chart used AI to offer users the option to create it based on the data. It was then created on a separate page and made available.

Has transformed how I manage documents through metadata and automation while enabling structured collaboration
Microsoft should restore some functionalities from older versions of Microsoft Office SharePoint Server 2003 and 2010. Specifically, bringing back something similar to SharePoint Designer would be beneficial. SharePoint Designer was both advantageous and challenging - developers found it limiting and preferred Visual Studio, while non-developers struggled to use it effectively. A new tool for configuring webpage design and development for content pages would be valuable. The current system is too basic. While integration of filtered lists and libraries is possible, it requires knowledge of Python or jQuery. A WYSIWYG editor would be preferable to requiring programming knowledge or Visual Studio.

Automation features and user-friendly interface support seamless communication
Slack is very supportive in terms of communication between my colleagues and clients. While working with the reimbursement feature, I found the automation capabilities on Slack to be incredibly useful, allowing me to automate messages for specific dates or times and even to greet someone on their birthday. I haven't specifically used the channel organization feature of Slack, as I am added to channels, but I use it with Airtable, which automates notifications to a specific Slack channel when a user fills out a form on our website. In my experience, Slack is a stable product for communication, and I appreciate its automation features and integration of AI capabilities for enhancing specific functions.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Scalability-wise, I rate the solution a ten out of ten."
"We have found limiting permissions and history very valuable."
"The customization that Confluence offers is one of its most useful features. You can customise it based on the specific project you are working on. It also supports multiple languages."
"Confluence can link any ticket or task from JIRA to be included on the Confluence page."
"It's easy to search for information."
"The most valuable features are hyper-linking, the Drawing Tool, and enhanced tables."
"Collaboration is most valuable. You can upload or create your documents on Confluence and share them with your team members. Your team members also can share documents."
"What I find the most valuable about Confluence is how easy it is to use."
"The most valuable feature is the "Alert Me", which provides the ability to set an alert when content is either added or changed and that the alerts can be either real-time or aggregated for the day or the week."
"The software is friendly to use for mixing data and analyzing it."
"The level of stability is good."
"The collaboration, the ability for multiple users to work on a single document."
"The most valuable feature of this solution is the Communication Site."
"Document management and records management features are the most valuable."
"The solution is scalable. You can do both horizontal and vertical scaling."
"It is a decent tool for collaboration, especially if you are already using other Office products."
"It's valuable for announcements and communicating between team members."
"Slack offers several valuable features. Firstly, they have a message deletion feature, which is now available in other software as well, but Slack was the one who introduced it in enterprise solutions."
"The integration with Google Calendar is easy to use and allows us to receive notifications before meetings."
"The most valuable feature for me was the different channels."
"Slack makes it easy for employees to contact each other and exchange documents or information."
"I use Slack for communication with my colleagues."
"Slack is very supportive in terms of communication between my colleagues and clients."
"It has become easier to use than Teams, which is the main benefit of Slack Business - Enterprise; it is simple and connected."
 

Cons

"When we import the data in Confluence from Word or any other document, the formatting is not correct."
"Some elements of the user interface could be more user-friendly, including embedding diagrams."
"The dashboards should be improved."
"Atlassian Confluence could improve how information is shared outside our company. We had some negative experiences with the rights we have with our information when sharing it within Atlassian Confluence and with other teams outside the company. It's due to the limitations on the rights we have on the export capabilities. We don't have sufficient rights to do so."
"It would be interesting if they had graphical templates that allowed typical agile ceremonies to be documented better."
"The way Atlassian Confluence handles tickets could be improved."
"There is a holiday calendar, however, I need to install an app or add something to it. The add-on feature is not readily available or well-documented."
"Atlassian Confluence's old versions consume too much memory, making it an area where optimization is required from an improvement perspective."
"It is a bit restrictive to develop in the cloud version. A lot of features are in the cloud now, and you have to develop on the outside. As far as the platform and the programming side of things are concerned, it is moving more towards configuration management rather than programming. When we are doing solutions, we are basically just configuring it to make solutions happen rather than actually using the Visual Studio code and developing from scratch in the cloud. It is almost like creating an app. You have created an app for your phone, but the app doesn't really sit on your phone. It sits somewhere on a server, and the database sits on another server. The app is just pulling and pushing information. The whole development has changed. We used to install things directly on the server and then run the application from the server. Now, it is more of a modular architecture."
"The solution needs to enable better sharing capabilities between users and external users. Several users also have problems with linking their emails to their Microsoft account."
"Sharepoint doesn't integrate well with Oracle, and we use a lot of Oracle products at our company. Therefore, it makes more sense for us to go to Oracle instead of continuing to use Sharepoint."
"I would like to see more Agile techniques and seamless integration with other applications."
"Making it more intuitive could help teams adopt it faster and use it more effectively by being more user-friendly."
"The GUI is outdated."
"Workflows could be simplified."
"The document management features of Microsoft Office SharePoint Server are not very good compared to OneDrive."
"Slack's Canvas feature could be improved in terms of its user experience."
"The solution should have less frequent updates."
"I have found it cumbersome to create and set up groups, or channels."
"The tool should be able to fetch a conversation when we search for it even if it is in the thread."
"I haven't experienced any noticeable return on investment since starting with Slack."
"The reason is we are moving towards a new CRM, so we have a suitable solution to integrate with the new CRM."
"The UI could be a little bit better."
"In Slack, there are areas for accessibility improvements."
 

Pricing and Cost Advice

"When you purchase this solution you get some support."
"We have a site license for Atlassian Confluence and there are some limitations on external users."
"There are some cases where you can go on Confluence as a public site without a license, but you will not have all of the features. You can also have a Confluence site that does not require a license just to read the articles. When you have Jira Service Management attached to Confluence, then you can go through the portal of Jira Service Management and read the Confluence articles without the license. This is good because when you are in an ITSM environment, you have many customers, and you do not want them to have to pay just to read articles. Regarding the use of the full features of Confluence, there is a license cost, and it depends on how many users you want."
"I am using the paid version. My company has purchased it for company employees. We are using Confluence as a company. I don't know how much it costs, but its price is good enough. Its price is not so high."
"The issues I have with the pricing are in respect to the add-ons."
"Licenses are quite expensive"
"Maybe we're only using 10% of it, but we have to pay for everything."
"We pay $350 a month to use the solution."
"One of the reasons why we don't recommend the cloud version of SharePoint is the cost. With the on premise version, you pay for the license once. For the cloud version, there is a recurring fee. It is very expensive. They expect everyone to pay $20 or $30 per user per month."
"It can be expensive for on-premises deployments, especially when you have to support SQL Server as your backend database. That's where the cost comes into play. SQL Server has its own licensing, which Microsoft keeps on changing. Therefore, it can become costly. In the earlier versions of SharePoint, version 2007 or 2010, they had an express version where the SQL Server licensing was free. It wasn't like a full-blown SharePoint. It was only a slimmed-down version. It used to be whatever your hardware costs. You would install the free software and work with it, but you were very limited in what you could do in SharePoint. If you wanted the SharePoint Enterprise Server with all the bells and whistles, then you had to pay more to get the SQL Server license based on the number of users or servers. The subscription model is different for cloud deployments. Licensing is per user and per month. The cost also depends on the storage required. If you have a lot of sites or documents, then you need to expand it based on your needs."
"There are some aggressive discounts offered by Microsoft for organizations that are not for profit, which we are, and it makes it quite attractive to consider."
"Pricing plans may be flexible depending on volume usage and your corporate relationship with Microsoft."
"The tool's pricing could be cheaper."
"I would rate the tool's pricing a four out of ten."
"It is an affordable solution."
"Slack is definitely worth the money."
"It is an expensive tool. We pay 15 to 20 USD monthly per user."
"We use the free version that does not have a license."
"It's on the more expensive side."
"The solution’s pricing is cheap."
