INTRODUCTION
In the dynamic realm of the telecommunications industry, understanding and leveraging data has become paramount for sustainable growth and customer satisfaction. This Churn Analysis project delves into the intricate patterns of user turnover, a critical aspect that can significantly impact a company's success. Through comprehensive data analysis, I aim to unearth actionable insights that not only shed light on the reasons behind customer churn but also empower telecom companies to implement strategic measures for enhancing customer retention. In an era where data is synonymous with competitive advantage, this analysis stands as a testament to the pivotal role data analysis plays in shaping the future of the telecommunications landscape.
PROJECT APPROACH
Data Source
The dataset for this analysis was obtained from Kaggle and encompasses a comprehensive array of customer-related variables. Key attributes include customer demographics (Gender, Age, Marital status), service specifics (Phone Service, Internet type, Contract duration), usage patterns (Monthly charges, Total revenue), and crucially, indicators of churn (Churn Category, Churn Reason).
Data Cleaning and Preprocessing
Commencing the Data Cleaning and Preprocessing phase, I strategically managed missing values by excluding columns with substantial data gaps deemed non-crucial. Emphasizing enhanced clarity, I employed formatting techniques such as bolding headers and restructuring the dataset. Delving deeper, DAX functions were utilized to compute crucial Key Performance Indicators (KPIs) for a comprehensive analysis. Specific headers were thoughtfully renamed to facilitate clear communication, establishing a dataset conducive to in-depth analytical exploration within our report.
Furthermore, I executed a meticulous process using the "find and replace" method to replace empty cells in the "Churn category " Column with "No churn" and "Not applicable" with "No churn" in the "Churn Reason" Column. Contract duration details underwent a concise transformation, changing from "One year," "Two years," and "Month to Month" to "1 Yr," "2 Yr," and "Mth-Mth" for improved legibility in visualizations.
I also addressed empty cells in columns that contain service specifics, "No sub" was assigned to cells with no subscription, signifying instances where service usage couldn't be measured due to each user's absence of a subscription.
Subsequently, the refined data was seamlessly transferred to Power BI for further comprehensive analysis.
USING POWER BI
In leveraging Power BI for analysis, I diligently verified the data types of each column to ensure their alignment with specific data details. Additionally, I introduced new measures pivotal to the depth of my analysis. These measures encompass essential Key Performance Indicators (KPIs) like Average Monthly Revenue per User (AVPU), Churn Count, Churn Rate, Count of Churned Customers, Customer Lifetime Value (CLV), Estimated Lifespan of Customers, Total Refunds, Total Revenue, Total Customers, and other pertinent details crucial to this analysis.
This step is of utmost significance as accurate data types are foundational for precise calculations and trustworthy visualizations, enhancing the reliability of derived insights. The newly introduced measures serve as quantitative benchmarks, offering a comprehensive snapshot of key aspects, including revenue, customer retention, and overall business performance. These KPIs provide valuable insights, steering strategic decision-making and enriching the understanding of the dataset's complexities.
DATA MODELING AND VISUAL INSIGHTS WITH POWER BI
Data modeling played a vital role in this project by structuring and defining relationships within the dataset. It ensured accurate representation of key variables such as customer demographics, service usage, and contract details to identify potential patterns influencing customer churn. This also enhanced the precision of calculating key metrics. This organized approach supported reliable visualizations which I will show below, enabling a more insightful exploration of this analysis. In essence, data modeling played an indispensable role in producing accurate, meaningful insights and facilitating informed decision-making throughout this analysis.
VISUALIZATION- UNCOVERING INSIGHTS AND TRENDS
In the presented visual analysis, key insights are gleaned from various aspects of the dataset, shedding light on critical factors influencing churn within the telecommunications company.
Each of these visualizations contributes to a comprehensive understanding of the dataset, facilitating strategic decision-making to reduce churn. The upcoming visuals will delve further into specific churn insights, providing a more nuanced perspective on customer behavior and potential areas for intervention to enhance customer retention strategies.
CHURN INSIGHTSIn this phase of the analysis, the second set of visualizations provides deeper insights into the churn dynamics of the telecommunications company. These findings illuminate critical factors influencing customer retention and overall business performance.
These findings, collectively analyzed, provide actionable intelligence for strategic decision-making. The correlation between contract duration, payment methods, demographics, and churn rates offers valuable insights to guide effective churn management strategies. Subsequent visualizations will further explore specific aspects, providing additional layers of insight for comprehensive churn analysis.
The final phase of the analysis delves into the intricate details of churn, shedding light on specific reasons behind customer attrition. This comprehensive view aids in understanding the dynamics of churn categories and their implications for the Californian telecommunications business.
The previous visualization reveals a total of 182 users for whom churn categories cannot be definitively determined. Notably, 46 users moved, 6 are deceased, and the churn reason for about 130 users remains unknown, emphasizing the challenge of pinpointing reasons for churn in this subset. This matrix also provides a granular breakdown of churn categories, uncovering specific reasons for customer attrition. This includes dissatisfaction with service, product, and price, as well as issues related to support expertise, network reliability, and additional charges. Noteworthy reasons include competitors offering more data, higher download speeds, better devices, and dissatisfaction with the attitude of support personnel and the service provider. The line and stacked column chart illustrate the relationship between estimated lifespan, average revenue, and customer status. It discerns that retained customers exhibit the highest estimated lifespan, followed by churned users, and then joined users. Simultaneously, the average revenue experiences a decline across these customer statuses.
Impact on the Business
These insights collectively provide a nuanced understanding of churn dynamics and their impact on this Californian telecommunication business. The challenges in determining reasons for churn in a subset of users highlight potential areas for improved data collection and customer feedback mechanisms. This detailed churn category pinpoints specific pain points experienced by customers, ranging from dissatisfaction with services and prices to competition-related factors. The inverse relationship between estimated lifespan, average revenue, and customer status underscores the correlation between customer retention, longevity, and financial contribution to the business.
Understanding these dynamics equips the business with actionable intelligence to implement targeted strategies. Addressing specific pain points identified in churn categories can lead to improved service offerings, and enhanced customer satisfaction, and ultimately contribute to reducing churn rates. Additionally, optimizing data collection processes for users with indeterminate churn categories can provide a more comprehensive understanding of the factors influencing customer attrition.
