Why your company needs a Slack wiki

Organizations capture information around their business in a central knowledge portal. When employees need access, they have to context switch from their core work, understand the organization of information in the knowledge portal, and optimally search for the information they are looking for. The information they need at a given moment is not easily accessible. Employees get reluctant to consume information from traditional knowledge sources. The challenges with adoption will affect motivation to keep the company wiki updated and vice versa. Eventually, this leads to a stale wiki that nobody is using or updating.

It is essential to solving the engagement problem to drive the adoption of your company wiki. It makes sense that Slack be the primary way for employees to access knowledge quickly and in context. Slack apps like Troopr allows you to integrate your company wiki right into Slack and automate the way company knowledge is surfaced and shared in Slack
