Please read below to answer the question for the opening Vignette

A telecom company (named Access Telecom [AT] for privacy reasons) wanted to stem the tide of customers churning from its telecom services. Customer churn in the telecommunications industry is common. However, Access Telecom was losing customers at an alarming rate. Several reasons and potential solutions were attributed to this phenomenon. The management of the company realized that many cancellations involved communications between the customer service department and the customers. To this end, a task force comprising members from the customer relations office and the information technology (IT) department was assembled to explore the problem further. Their task was to explore how the problem of customer churn could be reduced based on an analysis of the customers’ communication patterns (Asamoah, Sharda, Zadeh, & Kalgotra, 2016).

Big Data Hurdles

Whenever a customer had a problem about issues such as their bill, plan, and call quality, they would contact the company in multiple ways. These included a call center, company Web site (contact us links), and physical service center walk-ins. Customers could cancel an account through one of these listed interactions. The company wanted to see if analyzing these customer interactions could yield any insights about the questions the customers asked or the contact channel(s) they used before canceling their account. The data generated because of these interactions were in both text and audio. So, AT would have to combine all the data into one location. The company explored the use of traditional platforms for data management but soon found they were not versatile enough to handle advanced data analysis in the scenario where there were multiple formats of data from multiple sources (Thusoo, Shao, & Anthony, 2010).

There were two major challenges in analyzing this data: multiple data sources leading to a variety of data and also a large volume of data.

1. DATA FROM MULTIPLE SOURCES: Customers could connect with the company by accessing their accounts on the company’s Web site, allowing AT to generate Web log information on customer activity. The Web log track allowed the company to identify if and when a customer reviewed his/her current plan, submitted a complaint, or checked the bill online. At the customer service center, customers could also lodge a service complaint, request a plan change, or cancel the service. These activities were logged into the company’s transaction system and then the enterprise data warehouse. Last, a customer could call the customer service center on the phone and transact business just like he/she would do in person at a customer service center. Such transactions could involve a balance inquiry or an initiation of plan cancellation. Call logs were available in one system with a record of the reasons a customer was calling. For meaningful analysis to be performed, the individual data sets had to be converted into similar structured formats.
2. DATA VOLUME: The second challenge was the sheer quantity of data from the three sources that had to be extracted, cleaned, restructured, and analyzed. Although previous data analytics projects mostly utilized a small sample set of data for analysis, AT decided to leverage the multiple variety and sources of data as well as the large volume of data recorded to generate as many insights as possible.

An analytical approach that could make use of all the channels and sources of data, although huge, would have the potential of generating rich and in-depth insights from the data to help curb the churn.

Solution

Teradata Vantage’s unified Big Data architecture (previously offered as Teradata Aster) was utilized to manage and analyze the large multistructured data. We will introduce Teradata Vantage in Section 9.8. A schematic of which data was combined is shown in Figure 9.1. Based on each data source, three tables were created with each table containing the following variables: customer ID, channel of communication, date/time stamp, and action taken. Prior to final cancellation of a service, the action-taken variable could be one or more of these 11 options (simplified for this case): present a bill dispute, request for plan upgrade, request for plan downgrade, perform profile update, view account summary, access customer support, view bill, review contract, access store locator function on the Web site, access frequently asked questions section on the Web site, or browse devices. The target of the analysis focused on finding the most common path resulting in a final service cancellation. The data was sessionized to group a string of events involving a particular customer into a defined time period (5 days over all the channels of communication) as one session. Finally, Vantage’s nPath time sequence function (operationalized in an SQL-MapReduce framework) was used to analyze common trends that led to a cancellation.

Results

The initial results identified several routes that could lead to a request for service cancellation. The company determined thousands of routes that a customer may take to cancel service. A follow-up analysis was performed to identify the most frequent routes to cancellation requests. This was termed as the Golden Path. The top 20 most occurring paths that led to a cancellation were identified in both short and long terms. A sample is shown in Figure 9.2.

This analysis helped the company identify a customer before they would cancel their service and offer incentives or at least escalate the problem resolution to a level where the customer’s path to cancellation did not materialize.
