What should you look for when selecting an internal knowledge base?

Think about these 5 factors when evaluating your next knowledge base.

1. Does it have a good search function?

A knowledge base is only as good as its search capability. To be effective, it should be able to answer the query posed by the employee or customer accurately. To do this, it should ideally support deep searches, and make use of detailed search parameters.

2. How is the knowledge base UI?

The software or portal must be easy to use and have an intuitive interface, even for novice users.

3. Can you manage content easily?

Contributors should be able to submit and edit content quickly, while editors and admins in charge of the knowledge base should be able to edit and publish content efficiently and conveniently. 

4. How are its access controls?

For internal knowledge bases, you’ll want software should possess adequate access and permission controls for information security. For customer service knowledge bases, the portal should be protected from unauthorized revisions by external actors.

5. What does the knowledge base integrate with?

Make sure your chosen vendor integrates with your existing productivity tools. This could be anything from your CRM software to messaging tools, like Slack, MS Teams, or Google Docs.   

What’s the difference between internal and external knowledge bases?

The creation and management of a knowledge base channel is part of the broader field of knowledge management. Knowledge management aims to collect all the valuable knowledge, best practices and routines of the company for the benefit of the entire organization.

In terms of the audience, there are two types of knowledge bases:

The internal knowledge base is designed for use within the organization. As such, it usually possesses data security features like log-on credentials, permissions and access management.

On the other hand, an external knowledge base is meant for use by customers to find answers to common problems. As an open resource, it may not require a log-in credential. External knowledge bases may also be linked to other customer support channels such as chat support or contact pages in case the information displayed is insufficient, or doesn’t solve the customer’s issue. 

Who uses an internal knowledge base software?

The knowledge base is a very useful resource for different types of audiences. These include:

Customer support teams: An internal knowledge base provides your customer support and success teams a secure space to store sensitive or internal information that shouldn’t be shared with customers. It also contains procedural documentation, troubleshooting guides, and internal FAQs that assist support agents in resolving complex issues efficiently. Additionally, an internal knowledge base fosters collaboration among support team members, allowing them to share insights and solutions, ultimately enhancing the quality and speed of customer support.

Employees: In the course of their everyday tasks, whenever they need to look up data, a procedure, or information possessed by other departments. These are mainly for internal knowledge bases.

Customers: A self-help channel can help clients solve issues on their own instead of going through a customer support agent. External knowledge bases are set up for this.

New hires: For onboarding, training, or company culture

Promotions or lateral transfers: Allows them to get up to speed quicker 

Inter-department collaborations: When different teams or departments need to work together, the knowledge base offers a reliable source of information.

External partnerships: With the appropriate clearances and restrictions in place, external users like business partners, consultants, suppliers and agencies can also find the knowledge base useful.

What are the benefits of a good knowledge base software?

A good knowledge base software can bring a ton of benefits to your business, making it worth more than the initial time and investment required. These benefits include better customer service, higher productivity, and a connected source of truth. This article about choosing knowledge base software has more info.

How do I keep my knowledge base up-to-date?

There are two ways:

  • Assign a panel of moderators to manage the content, including updating, revisions and approval of submissions.
  • Crowdsource the content creation by letting employees submit new topics, revise or update existing material, just like a wiki.

To ensure that your knowledge base stays relevant and updated, it is useful to have a knowledge management strategy.

Who is in charge of managing the knowledge base?

A knowledge manager should be appointed to oversee the implementation and maintenance of the knowledge. The knowledge manager will ideally come from a related field, such as project management, training and development, or IT.

For more information, see our article “What is a Knowledge Manager, and Why Do You Need One?

What software integrations should an internal knowledge base software have?

The internal knowledge base should integrate with your organization’s preferred messaging app like Slack or MS Teams, so that employees can quickly share and collaborate knowledge.

Likewise, it should ideally support productivity tools, so that users can look up information without leaving the tool or app they are currently using.
