Centro is a global business process outsourcing company operating contact centers for clients across healthcare, retail, and financial services. This post explains how our quality assurance process works and how it supports a 91% customer satisfaction rate.

In the world of contact center outsourcing, quality is everything. It is what turns everyday customer interactions into experiences that build trust, loyalty, and long-term growth.

At Centro, we take that seriously. Maintaining a 91% satisfaction rate across our global delivery centers does not happen by chance. It comes from a deeply ingrained commitment to excellence, innovation, and people.

Why Quality Assurance Is More Than Just a Process

For many organizations, outsourcing customer support is a strategic move. It allows them to focus on growth while ensuring that customers receive the attention they deserve. But none of that matters without one key ingredient: quality assurance.

At Centro, QA is not a one-time check or an end-of-month report. It is part of everything we do. Every conversation, every ticket, and every data point is measured, analyzed, and optimized to ensure we deliver experiences that truly represent our clients’ brands.

The State of Quality Assurance in Contact Centers

According to COPC Inc.’s Global Benchmarking Series, 92% of organizations have a formal QA program in place. Having a program and using it to drive customer experience improvement are different things. Manual review typically covers only a small percentage of total interactions, which leaves most conversations unexamined.

That gap is why automation and data-driven QA tools are becoming central to contact center performance.

The outsourcing market itself continues to expand. Grand View Research values the global call and contact center outsourcing market at $102.9 billion in 2025, projected to reach $240.5 billion by 2033. As more customer interactions move to outsourced providers, the quality standards governing those interactions carry more weight.

These figures highlight one thing: as customer expectations rise, QA must evolve from a traditional control function into a strategic capability.

Future Trends in Call Center QA

The world of contact center quality assurance is evolving quickly, shaped by new technologies and changing customer expectations. Here are the top trends defining QA in 2025 and beyond:

1. Emerging Technologies

AI and machine learning are transforming QA. By 2027, AI will handle 60% of QA tasks, helping teams forecast customer issues before they occur and improving overall efficiency and CX.

2. Proactive and Predictive QA

Instead of reacting to issues, contact centers are using predictive analytics to prevent them. By identifying trends such as long average handle time or high escalation rates in real time, QA teams can act faster. Predictive QA has been shown to improve CX by 15%, and in one retail example, it reduced escalations by 10%.

3. Integration of Omnichannel QA

As omnichannel support expands, QA now includes phone, chat, social media, and email to ensure customers receive a consistent experience everywhere.

4. Focus on Agent Well-Being

The next phase of QA will emphasize agent wellness. AI tools are already being used to monitor stress levels and provide personalized support, resulting in 12% higher agent retention.

These innovations prove that QA is no longer just about measuring performance—it is about enhancing the human experience for both customers and agents.
