• External factors like economic conditions and competitive landscape impacting customer churn are not considered in analysis.
• Analysis might not facilitate personalized strategies for individual customer retention due to generalized findings from aggregated data.
• Analysis might provide insights at a specific point, lacking continuous monitoring and adjustment to adapt to evolving customer behaviors.
• Analysis is based on the historical data and this may be not true in future.
• This project will not accurately predict the customer churn in future.
