Identification of the Key Metric:

In this case, the key metric that has fallen is daily active users (DAU) in India. This is an important metric as it signifies user engagement.

Investigate Nature of the Drop:

Next, I would seek to understand whether this 20% drop was a sudden or a gradual one. If it was sudden, I would look for specific incidents or changes that occurred around the same time. If it was gradual, it might indicate a shift in user behavior or market dynamics, which requires a different approach.

Examine Possible Internal Factors:

Some possible internal factors could be changes to the platform (like UI/UX changes, pricing adjustments), technical issues (like server downtime, app crashes), or changes in the algorithm that may have negatively affected user experience specifically in India. It might also be a consequence of poor data tracking, so I would verify the accuracy of this metric drop as well.

Examine Possible External Factors:

In terms of external factors, this could involve a new competitor gaining market share, legal or regulatory changes in India, shifts in consumer behavior, economic conditions, or even the launch of a large-scale event by a competitor. There could be cultural or language issues that are specific to the Indian market that have caused this drop.

Analyze Related KPIs:

After that, I would check if there are other related KPIs that have seen changes. For instance, if the churn rate has increased, or if the user acquisition rate has decreased, it might provide some insight into the situation.

Collaborate with Relevant Teams:

If the issue seems to be internal, such as a bug or server problem, I would coordinate with the engineering and IT teams to resolve it quickly. If it's a more strategic issue, such as pricing or UI/UX, I would work with those respective teams to discuss potential modifications.

Develop a Response Plan:

Depending on the root cause, the response plan might include improving the product features, changing marketing strategy, strengthening the server infrastructure, addressing bugs, improving customer support, or conducting a more localized user research to understand the unique needs and behavior of the Indian user base.

Communicate with Stakeholders:

It's essential to keep all stakeholders informed about the situation and the steps being taken to address it. This includes internal teams, senior management, and potentially the users themselves, if appropriate.

Monitor the Metrics:

After implementing changes, closely monitor the DAU and other related metrics to see if the situation improves.
