Room For Improvement

Users seek improvements in Confluence's search, UI, integration, collaboration, content organization, pricing, and project management features.

Slack Business requires enhancements in video, integration, notifications, organization, customization, security, AI, multimedia sharing, and scheduling.
The company using Atlassian Confluence needs to have a very clear structure for where information will be organized.

Enterprise buyers find Atlassian Confluence costly due to licensing, user volume, and plugin-related expenses, requiring strategic cost management.
Enterprise SharePoint pricing varies widely; careful planning and professional guidance are essential for cost-effective, tailored solutions.

reviewer2811600 - PeerSpot reviewer
SDE 1 at a educational organization with 501-1,000 employees
Centralized document governance has boosted collaboration and made knowledge sharing structured
SharePoint is a powerful platform, but there are a few areas where I think it could be improved, such as user experience. For new users, the interface and navigation can feel quite complex, specifically when working with multiple sites and document libraries. Another improvement would be search functionalities. While it is good sometimes, it does not always return the most relevant result unless a document is very well-structured and tagged. Also, initial setup and customizations can be time-consuming and may require technical expertise, specifically when configuring workflows or permissions. From a modern development perspective, tighter and more seamless integrations with tools including Power Automate and better support for custom backend integrations through APIs could make it more efficient. Overall, simplifying usability and enhancing search and integration capability would make SharePoint even stronger. One additional area I would appreciate improvement would be performance and responsiveness, especially when dealing with a large document library. Sometimes loading or navigating through large datasets can feel quite slow. Another aspect is permissions management. While it is very powerful, it can become complex to manage at scale, specifically when there are multiple levels of access across teams and projects. Improving developer experience would also be beneficial. Making customization, API integrations, and extensions more straightforward would help teams, especially backend developers, leverage SharePoint more efficiently.
Akhil Viswam - PeerSpot reviewer
Senior Consultant at a consultancy with 10,001+ employees
Threaded collaboration has transformed how our team tracks tickets and monitors automation updates
One suggestion I would make for improving Slack Business - Enterprise is the support of multimedia such as images and videos that we can easily share through Slack. That would be great. Additionally, another thing is AI integration; if Slack has some AI capabilities to get insights about conversations or summarization, that would be a great feature. If Slack has an AI feature that can summarize a particular Slack thread and provide a summary of that, that would be a great feature for us. I would rate it a ten if it comes with some AI features, particularly using generative AI to produce summarization and other kinds of insights from communication in a more secure, data-secure way.
