Top 14 internal wiki tools | Introducing services that help you share information within your company

This post is also available in: 日本語


Here are a few suggestions for the 2020 version of the internal wiki tool.

What is an internal wiki?

An internal wiki is a tool that organizes the company’s stock information, including rules, manuals, structures, and know-how. It’s the same concept as Wikipedia, an online encyclopedia that anyone can edit and make together.

Why an internal wiki?

The more work you do, of course, the more information you accumulate. As information accumulates, the need for efficient access to that information increases. Systematic information gathering is critical because failure to get the right information can lead to lost productivity.

Key activities that leverage in-house Wiki tools

Specifically, what kind of work can be used for the in-house wiki? Here are some examples:.

  • Internal Structure
  • business flow
  • Place for job regulations
  • Responsibilities and rosters of each team
  • Track important announcements
  • storage of know-how
  • Location of various manuals


Key points in choosing an in-house Wiki tool

Here are a few key points to consider when choosing an in-house Wiki tool:.

Flexible permission settings

Flexibility in who can create and who can view them reduces the likelihood of confusion in your organization’s information management. It is a very important function in terms of organizing information that can be viewed by job type and layer and information that is not.

You can check the edit history.

Wiki tools are basically a constant update. That’s why it’s important to be able to see the latest version and who updated it. If you accidentally edit it, it’s important to be able to return to the correct version.

Be highly searchable

The more searchable an internal wiki is, the more useful it is. It is important to be able to access the document directly without having to memorize which folder to access.

There are many formats for viewing information.

The more formats you stock on the internal wiki, the more useful it is. For example, tools that allow you to instantly view information in a variety of formats, such as storing video content and viewing PowerPoint content as is, are very useful.

Diverse collaboration with external services

One of the more important aspects of choosing a wiki tool is its integration with external tools. For example, the more collaborative a Wiki tool is, such as posting updates to the targeted Slack channel, the more efficient the team becomes.

affinity with internal infrastructure

I think the compatibility with the services already used in the company is one of the selection points. For example, if you’re already using Jira, it’s easier to work with Confluence, and if you’re using Microsoft Teams, you can use the Wiki feature seamlessly. Considering the internal infrastructure environment beforehand, you can use it without additional operations.
