Flevy Management Insights Case Study
Customer Experience Re-engineering in Telecom


There are countless scenarios that require DMADV. Fortune 500 companies typically bring on global consulting firms, like McKinsey, BCG, Bain, Deloitte, and Accenture, or boutique consulting firms specializing in DMADV to thoroughly analyze their unique business challenges and competitive situations. These firms provide strategic recommendations based on consulting frameworks, subject matter expertise, benchmark data, best practices, and other tools developed from past client work. Let us analyze the following scenario.

Reading time: 10 minutes

Consider this scenario: The organization is a mid-sized telecommunications provider facing escalating churn rates and declining customer satisfaction scores.

Despite investing heavily in customer service and support infrastructure, the company has not seen a corresponding increase in customer loyalty or market share. The challenge is to leverage DMADV to systematically improve the customer experience, thereby enhancing satisfaction and reducing churn.



The initial observation suggests that the organization's customer experience strategy may not be aligned with customer expectations or industry benchmarks. One hypothesis could be that the customer service workflows are not optimized for efficiency and effectiveness. Another could be that the customer feedback mechanisms are not adequately capturing the voice of the customer, leading to misinformed strategic decisions. Lastly, it's possible that employee training and engagement do not fully support a customer-centric culture.

A comprehensive DMADV (Define, Measure, Analyze, Design, Verify) methodology will guide the optimization of customer experience processes. This data-driven quality management framework is beneficial for creating processes that are repeatable, measurable, and capable of meeting customer needs.

  1. Define: Identify critical customer touchpoints and define the desired customer experience at each stage. Key questions include: What are the customer's expectations? What is the current experience? Activities include stakeholder interviews and mapping the customer journey.
  2. Measure: Collect data on current performance metrics. Key activities include customer satisfaction surveys and analysis of support interaction logs. Insights into where the experience falls short are crucial, as are common challenges like data silos.
  3. Analyze: Analyze the data to identify gaps between the current and desired customer experiences. This phase involves root cause analysis and identifying improvement opportunities.
  4. Design: Develop solutions to bridge the experience gaps. This involves redesigning processes, training staff, and implementing new technologies. Potential insights include innovative customer service techniques and digital transformation initiatives.
  5. Verify: Test the redesigned processes and verify their effectiveness. This includes pilot programs and collecting post-implementation data to ensure the changes have led to the desired improvements.

Key Considerations

Senior leaders may wonder how this methodology will integrate with existing operational structures. The DMADV approach is designed to be complementary, working within the framework of the organization's current operations to enhance, rather than disrupt, service delivery.

Another concern may be around the time and resources required to implement such changes. While there are upfront investments, the long-term benefits include increased customer retention, which is far more cost-effective than acquisition.

Finally, the adaptability of the DMADV process to the rapidly evolving telecom industry might be questioned. The methodology is inherently flexible, allowing for continuous improvement and iteration as market conditions and customer expectations change.

Expected business outcomes include a 10-15% reduction in churn rates and a 20% improvement in customer satisfaction scores within the first year of implementation. Streamlining customer service processes can also lead to a 30% reduction in service-related costs.

Potential implementation challenges include resistance to change from employees, the complexity of integrating new technologies with legacy systems, and ensuring consistent execution across all customer touchpoints.

DMADV Best Practices

To improve the effectiveness of implementation, we can leverage best practice documents in DMADV. These resources below were developed by management consulting firms and DMADV subject matter experts.

Adapting DMADV to a Changing Telecom Industry

The telecom industry is characterized by rapid technological advancements and changing consumer behaviors. The DMADV methodology, with its emphasis on the Measure and Analyze phases, is designed to be adaptive. For example, during the Analyze phase, the organization can use tools like sentiment analysis to understand changing customer sentiments in real-time, allowing for quick adjustments to service strategies.

Furthermore, the Verify phase is critical in ensuring that the improvements are yielding the desired outcomes. According to a Gartner report, 89% of businesses compete primarily on customer experience. This suggests that telecom providers must continuously iterate and refine their customer experience strategies to stay competitive. DMADV's iterative nature fits well with this requirement, enabling telecom companies to remain agile and responsive.

Overcoming Implementation Challenges

Resistance to change is a common challenge in any transformation project. To address this, companies must invest in change management practices. For example, creating a sense of urgency and communicating the vision for change can help in aligning employees with the new direction. Regular town halls and workshops can be used to address employee concerns and gather feedback.

When it comes to integrating new technologies, Accenture highlights the importance of adopting a "fail fast" approach to innovation. This means quickly prototyping and testing new solutions, learning from failures, and iterating. Such an approach can mitigate the complexity of technology integration by breaking it down into manageable experiments.

Improving Customer Service Efficiency

Streamlining customer service processes often leads to improved efficiency. For instance, implementing AI chatbots for handling common inquiries can reduce Average Handle Time (AHT) and increase First Contact Resolution (FCR) rates. According to Deloitte, chatbots can handle up to 80% of routine questions. This allows human agents to focus on more complex issues, improving overall service quality.

In addition, re-engineering workflows to remove unnecessary steps can drastically reduce the effort required to resolve customer issues. This not only improves the Customer Effort Score (CES) but also has a direct impact on employee satisfaction, as they are able to perform their tasks more efficiently.

Measuring Success with KPIs

KPIS are crucial throughout the implementation process. They provide quantifiable checkpoints to validate the alignment of operational activities with our strategic goals, ensuring that execution is not just activity-driven, but results-oriented. Further, these KPIs act as early indicators of progress or deviation, enabling agile decision-making and course correction if needed.


Tell me how you measure me, and I will tell you how I will behave.
     – Eliyahu M. Goldratt

Net Promoter Score (NPS) is a widely used metric for gauging customer loyalty. A study by Bain & Company found that leaders in NPS grow at more than twice the rate of their competitors. This underscores the importance of tracking NPS as part of the DMADV implementation KPIs.

Other KPIs like CES and FCR are also vital. They provide insights into the operational aspects of customer service. By tracking these metrics before and after implementing DMADV, the organization can quantify the impact of the changes. For example, a reduction in AHT indicates that processes are more efficient, while an improvement in FCR suggests customers are getting better first-time support.

Enhancing Employee Training Programs

A critical aspect of the DMADV implementation is the focus on employee training programs. These programs should not only cover the technical aspects of new processes and tools but also emphasize soft skills such as empathy and communication. According to McKinsey, companies that excel at customer experience have employees who are 1.5 times more engaged than less customer-focused companies.

Moreover, continuous learning opportunities should be provided to ensure that employees keep up with the latest industry trends and customer service innovations. This could include regular workshops, e-learning modules, and participation in industry conferences. Investing in employee development is a key factor in sustaining a customer-centric culture.

Utilizing Advanced Analytics and AI

Incorporating advanced analytics and AI in the Analyze phase can significantly enhance the understanding of customer needs and behaviors. For example, predictive analytics can help in anticipating customer issues before they arise, leading to proactive customer service. According to PwC, AI is set to become a "mainstream customer experience investment" in the coming years, with 72% of business decision-makers believing it will offer a competitive advantage.

AI can also personalize customer interactions by analyzing past behaviors to tailor recommendations and support. This level of personalization can be a key differentiator in the telecom industry, where products and services are often commoditized.

Creating a Continuous Improvement Culture

The Verify phase is not the conclusion of the DMADV process but a gateway to continuous improvement. A culture that values feedback and iterative development is essential for sustaining enhancements in customer experience. Real-time data analytics enable the organization to monitor performance and quickly adapt to changes in customer expectations or market conditions.

Encouraging a test-and-learn environment, where employees are not afraid to experiment and learn from failures, is crucial. This approach fosters innovation and keeps the company at the forefront of customer experience excellence. As per a report by McKinsey, organizations that continuously iterate and refine their customer experience see a 10-15% increase in revenue and a 20% increase in customer satisfaction.
