How we automated FAQ responses at Grab

摘要

Knowledge management is often one of the biggest challenges most companies face internally. Teams spend several working hours trying to either inefficiently look for information or constantly asking colleagues about information already documented somewhere. A lot of time is spent on the internal employee communication channels (in our case, Slack) simply trying to figure out answers to repetitive questions. On our journey to automate the responses to these repetitive questions, we needed first to figure out exactly how much time and effort is spent by on-call engineers answering such repetitive questions.

We soon identified that many of the internal engineering tools’ on-call activities involve answering users’ (internal users) questions on various Slack channels. Many of these questions have already been asked or documented on the wiki. These inquiries hinder on-call engineers’ productivity and affect their ability to focus on operational tasks. Once we figured out that on-call employees spend a lot of time answering Slack queries, we decided on a journey to determine the top questions.

We considered smaller groups of teams for this study and found out that:

• The topmost user queries are “How do I do ABC?” or “Is XYZ broken?”.
• The second most commonly asked questions revolve around access requests, approvals, or other permissions. The answer to such questions is often URLs to existing documentation.

These findings informed us that we didn’t just need an artificial intelligence (AI) based autoresponder to repetitive questions. We must, in fact, also leverage these channels’ chat histories to identify patterns.
