[How would you measure the success of Facebook Groups?](https://www.interviewquery.com/questions/group-success)

Try answering this on your own before continuing. Use the hints below if you are stuck.





What is the point of Facebook Groups? Primarily we could say Facebook Groups provides a way for Facebook users to connect with other users through a shared interest or real-life/offline relationship. 

How could we use the goals of Facebook Groups to measure success?


As we further define the user’s goal, we can narrow it down to feeling a sense of community. By doing so, we derive our business goal of increasing user engagement with Facebook Groups.

What general engagement metrics can we associate with this value?


When defining metrics, we prefer metrics that are objective. The most obvious metric is that of monthly active users, which we can monitor to see if this metric is increasing or decreasing.

We may also want to monitor general engagement metrics such as posting, commenting, and sharing.


# Solution

One thing that helps with product questions is to go back to the raw understanding of what the product feature is for.

Facebook Groups provide a way for Facebook users to connect with other users through a shared interest or real-life/offline relationship. This space enables these Facebook users to easily socialize in a group-like setting, planning events, discussing topics, etc. Facebook also allows groups to be private or closed off, or more open and public-facing.

The power of Facebook groups is bringing the world closer by uniting individuals from all over the world over shared interests, but even when this happens, users may not feel a sense of community.

Let's think about how we then need to deliver on the user goals:

* By making sure that a group is welcoming
* By encouraging  friendly associations
* By maintaining a supportive and respectful environment
* By ensuring that the group is active
* By ensuring that users find it easy to communicate with each other


In this case, the user’s goal is to experience a sense of community. By doing so, we derive our business goal of increasing user engagement with Facebook Groups. What general engagement metrics can we associate with this value?

For example, we need something objective. The most obvious is monthly active users, which we can monitor to see if this metric is increasing or decreasing. We may also want to monitor general engagement metrics such as posting, commenting, and sharing.

What about something that seems more intuitive? In this case, we can think about newsfeed quality and examine if Group posts clog the newsfeed or contribute to higher engagement levels. There is also the possibility of adding more diversity of opinion and exposing users to new “things” (events, people, etc.).


## User flows

Let’s additionally think about how a user interacts with Groups. This way, we can go through the flow mentally to understand the interactions that a user has with the actual product.
