Room For Improvement

Atlassian Confluence struggles with search, pricing, user interface, editing, integration, administrative roles, and reporting features needing improvement.
SharePoint needs improvements in co-authoring, permissions, search, integration, mobile optimization, user interface, workflows, and interoperability for better usability.

This chart used AI to offer users the option to create it based on the data.

Configuring chats and pinning in Teams is easier, even though Slack has these features, they are not intuitive enough to engage with.

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.

Streamlined collaboration through seamless integration and customization
I have been an administrator for SharePoint and have used it as an end-user for document storage. Predominantly, I've been involved in administration SharePoint helps a lot since we've moved from using it directly to using it as a backend for Teams, which makes collaboration easier. It supports…

A competitive solution that improves collaboration and productivity
Slack has been around for a long time, and it's an industry leader. Of course, Salesforce owns Slack now and is starting to integrate into it. I have attended Slack conferences and met with product and support managers. They're an excellent organization. Choosing Slack depends on the organization's size, so you need to plan your deployment and make sure you put some controls and standards in place and not just turn it on. If you're a Slack shop, you will have to have something like a Zoom or Microsoft Teams platform for when you need to do video conferencing internally or externally. Many shops have both products, but they use Slack for collaboration, chat, and so on, and use Teams for video and audio conferences. At the end of the day, Slack is missing those capabilities, so either you're going to be a Slack/Zoom shop or you're going to be a Microsoft Teams shop. I rate Slack an eight out of ten.

Jive vs Sharepoint vs Drupal Commons
At Mediacurrent we often get requests to compare Drupal to other platforms used for intranet sites and social business platforms (like https://dev.twitter.com/ for example). This is often referred to as “Social Business Software”, which has grown in popularity in recent years. I decided to do a…
