Case Study on Google Cloud for Call Centers

Introduction:

In today’s competitive business landscape, delivering exceptional customer service is paramount for retaining customers and gaining a competitive edge. Call centers play a crucial role in this domain, serving as the frontline for addressing customer inquiries, concerns, and support requests. To streamline operations and enhance customer satisfaction, many organizations are turning to cloud-based solutions. This case study explores how  a leading telecommunications provider utilized Google Cloud to improve customer service at its call centers.

            HSBC: Using Google Cloud to Improve Customer Service at Call Centers

            HSBC is a digital bank, with over 90% of its retail transactions globally and in Hong Kong being conducted through digital platforms.

            However, while digital banking is increasingly popular, call centers remain an important service and business channel. The Hong Kong Contact Centre for HSBC, which celebrated its 30th anniversary in 2020, serves over 1.5 million customers through over 20 million annual interactions.

            Enter HSBC’s Intelligence Hub

            The Intelligence Hub is a team of data scientists, engineers, and architects dedicated to migrating data and analytics workflows onto Google Cloud and looking for ways to leverage the data using AI and machine learning. This team works closely with different departments and business units to design and build end-to-end data and AI solutions.

            The HSBC Intelligence Hub is a team of data scientists, engineers, and architects dedicated to migrating HSBC data and analytics workflows onto Google Cloud and looking for ways to leverage the data using AI and machine learning. This team works closely with different departments and business units within HSBC to design and build end-to-end data and AI solutions.

            “People in the team come from a broad range of disciplines and backgrounds, from mathematics, business, computer science, behavioral economics, and engineering. You don’t necessarily have to be an expert in statistics. The most important thing is for our people to stay curious and have a drive to learn new things,” says Richard Bates, Global Head of HSBC’s Intelligence Hub.

            “Google is one of our strategic partners,” continues Richard. “We’re investing in machine learning and data capabilities with them because their cloud solution is approved to handle personal information securely and reliably.”

            “As we continue to build a customer-centric culture, data empowers us to conduct a more scientific and quantifiable assessment of our services,” adds Yusuf Demiral, Head of Data and Analytics, Asia Pacific at HSBC. “We see AI as an opportunity to better understand customers’ needs, hear their voices, and alleviate the risks for customers and our bank.”

            An Automatic Quality Management System

            Within the Intelligence Hub is the Data Science Squad, led by Mary Chu, Senior Analytic Architect, who took on the Contact Centre Language processing challenge.

            “We turned to AutoML Natural Language and Speech-to-Text to train machine learning models to classify, extract, and detect customer sentiment,” says Mary. “Using Google Cloud computing resources and BigQuery as a data analytics warehouse, we applied Speech-to-Text powered by Google’s AI technologies to the data, which accurately converted spoken combinations of Cantonese and English.”

            The result was an Automatic Quality Management system (AQM), the first in-house voice-processing solution powered by AI that helps to identify areas of improvement in customer conversations, a key milestone for HSBC’s Hong Kong Call Centre.

            Better Agent Service

            The HSBC Intelligence Hub Data Science Squad completed this development in just three months, and, working closely with 10+ HSBC teams, launched the solution in September 2020.

            “With Google Cloud, we could run a machine learning model in an hour, rather than a full week as would have been required in an on-premises environment, which considerably shortened our rollout time,” says Mary.

            HSBC now processes through this solution every Cantonese-English call into the contact center that involves presentation of information on terms and conditions.

            The solution helps the institution quickly identify sales agents with room for coaching and improvement. The monitoring team automatically receives alerts to such calls, which enables them to follow up with agents in a timely manner. It also allows HSBC to capture more insights to sharpen the way the bank serves its customers. “These insights also become valuable resources for us when we design our future customer journeys or work on staff training and reinforcement. Theoretically, it will involve 1,200 man-hours to monitor 100% of our sales calls. It is now unnecessary to spend this amount of time for monitoring,” says Richard.

            Optimizing ATM Cash Stocks

            Over the last six months, the HSBC Intelligence Hub has used its Data Science Workbench to develop capabilities in addition to AQMs. For example, HSBC has launched an internal tool, known as iCash, that predicts the stock of cash in ATMs and enables optimization to ensure they never run out of cash. iCash also provides strategic solutions for cash forecasting and planning for further development and rollout.

            Conclusion:

            By harnessing the power of Google Cloud, successfully transform call center operations, delivering superior customer service while optimizing operational efficiency. The implementation of Google Cloud Contact Center AI and Google Cloud Platform empowered the company to address key challenges, improve scalability, and gain valuable insights into customer interactions. As a result, a company  solidifies its position as a customer-centric organization committed to delivering exceptional service experiences.
