TL;DR: MS Teams and Slack are the top 2 choices for instant communication, and Tettra is the choice for internal documentation and processes.

The pandemic-induced shift to remote work has brought new challenges and emphasized the importance of internal communication and a shared knowledge base

According to a recent study by Gallagher, 68% of employers plan to reset their internal communication strategies in 2023 to adapt to the changing work environment. The study also found that 70% of organizations consider improving internal communication a top priority for the coming year. 

With the right tools, businesses can improve their internal processes, communication, collaboration, and productivity, regardless of location.

As businesses continue to navigate the challenges of remote work, it has become increasingly important to have effective internal communication channels, such as async communication.

What are the types of internal communication software?

Internal communication is used to facilitate communication within an organization. It helps ensure everyone is on the same page and that information is shared effectively, especially in the digital workplace age.. Internal communication can take many forms, including team meetings, emails, and instant messaging. Businesses need effective internal communication and efficient internal documentation to achieve their goals and stay competitive.

There are several types of internal communication software, including:

  • Team messaging apps enable teams to communicate in real time through instant messaging. Examples include Slack, Microsoft Teams, and Google Chat.
  • Project management software enables teams to collaborate on projects, assign tasks, and track progress. Examples include Asana, Trello, and Monday.com.
  • Collaboration apps enable teams to collaborate on documents, presentations, and other projects in real time. Examples include Google Docs, Dropbox Paper, and Notion.
  • Intranets or internal knowledge bases that are accessible only to employees can be used for sharing company news, policies, and other information. Examples include SharePoint and Confluence.

Why do you need internal communication software?

Without proper internal communication, team members may feel disconnected, leading to misunderstandings, missed deadlines, and a lack of accountability.

Here are some of the key reasons why businesses need internal communication software:

  • Facilitating Collaboration: Internal communication software enables team members to collaborate on projects, share ideas, and provide real-time feedback. This can help ensure everyone is working toward the same goal and that the project progresses smoothly.
  • Enhancing Productivity: With internal communication software, team members can easily communicate about project timelines, status updates, and deliverables, leading to more efficient work processes and increased productivity.
  • Improving Transparency: Internal communication software can help create a more transparent work environment, allowing team members to see what others are working on, the progress they are making, and any potential roadblocks.
  • Encouraging Innovation: With the ability to share ideas and provide feedback, internal communication software can help foster a culture of innovation within a business. This can lead to new ideas, processes, and products that can help the business grow and stay ahead of the competition.
  • Supporting Remote Teams: With the rise of remote work, internal communication software has become even more important for businesses.

By choosing the right internal communication software, businesses can create a more efficient and effective work environment, leading to greater success and growth.
