Call center quality assurance (QA) is essential for maintaining high service standards. But traditional QA in call centers relies heavily on manual evaluations, where QA teams review only a small percentage of calls. This approach is slow, inconsistent, and leaves gaps in visibility.
That’s why many companies are shifting to automated quality assurance (Auto QA). With AI and automated quality analysis, call centers can evaluate 100% of customer interactions instead of just a fraction. This improves accuracy, speeds up feedback, and helps managers spot trends across all calls.
But does this mean manual QA is obsolete? Not at all. A hybrid approach—combining Auto QA for large-scale monitoring with manual reviews for coaching and nuance—delivers the best results.
What is Manual QA in Call Centers?
Manual QA is the backbone of call center quality assurance. It gives teams the ability to dig deep into customer interactions, assessing not just what was said, but how it was said. QA analysts listen to calls, review transcripts, and evaluate agent performance based on predefined scorecards. This process helps uncover root causes of customer issues, pinpoint coaching opportunities, and ensure agents follow compliance guidelines.
Why Manual QA is Essential
Manual QA provides insights that automation alone can’t fully capture:
- ✅ Human expertise: Analysts assess tone, intent, and emotional cues to evaluate soft skills like empathy and active listening.
- ✅ Root cause analysis (RCA): By analyzing specific cases, teams can identify trends, policy gaps, and operational inefficiencies that impact performance.
- ✅ Coaching and training insights: QA teams provide personalized feedback tailored to an agent’s strengths and areas for improvement.
Challenges of Manual QA
While manual QA is invaluable for in-depth analysis, it comes with scalability challenges:
- 🔹 Limited coverage: Only a small percentage of interactions can be reviewed, often chosen at random, which may not reflect broader trends.
- 🔹 Time-consuming process: Reviewing calls, analyzing transcripts, and completing evaluations takes significant effort.
- 🔹 Delayed feedback: Since evaluations take time, agents may receive coaching weeks after an interaction, making it harder to course-correct in real time.
Despite these limitations, manual QA remains a critical piece of call center quality monitoring. It ensures that businesses don’t just track surface-level performance metrics but truly understand the “why” behind customer interactions.
What is Automated QA?
Auto QA transforms call center quality assurance by using AI, conversation analytics, and automation to analyze 100% of customer interactions. Instead of relying on random sampling, Auto QA processes every call, chat, and email, identifying trends, compliance risks, and coaching opportunities at scale.
How Auto QA Works
Auto QA applies AI-driven speech and text analysis to evaluate interactions based on customized quality criteria. It detects keywords, sentiment, policy adherence, and escalations—all in real time. This allows QA teams to move beyond limited manual reviews and gain a data-driven view of performance.
Why Auto QA is a Game-Changer
- ✅ Scalability: Evaluates all interactions, ensuring nothing is missed.
- ✅ Consistency: Applies the same scoring criteria across every call, eliminating human bias.
- ✅ Real-time insights: Surfaces trends immediately, allowing for proactive coaching and adjustments.
- ✅ Compliance monitoring: Flags policy violations, regulatory risks, and customer escalations before they become major issues.
Limitations of Auto QA
While automated quality assurance delivers broad insights, it has its own challenges:
- 🔹 Lacks human context: AI can detect words and tone, but it may misinterpret intent or emotional nuance.
- 🔹 Struggles with complex, business-specific evaluations: Certain policy nuances, contextual decision-making, and industry-specific compliance factors require human expertise to assess accurately.
- 🔹 Not all criteria are measurable by AI: Some process adherence, discretionary judgment, and situational responses need manual review.
- 🔹 Requires setup and calibration: Auto QA doesn’t work perfectly out of the box. It needs fine-tuning to match business-specific criteria and ensure accurate scoring. Without advanced AI calibration tools, AI may misclassify interactions or miss critical nuances.
While Auto QA streamlines large-scale monitoring, manual QA remains essential for deep analysis, coaching, and uncovering complex issues. Together, they create a more effective, data-driven QA strategy.
Key Differences of Manual and Auto QA
Both manual QA and automated quality assurance play an important role in call center quality assurance. But they serve different purposes. Manual QA provides deep insights and human expertise, while Auto QA delivers scale, speed, and consistency.
Each approach has unique strengths. Manual QA is critical for root cause analysis, deep-dive coaching, and evaluating nuanced customer interactions. Auto QA ensures every interaction is analyzed, helping teams spot trends, surface coaching opportunities, and act on performance insights faster.
But they work best together. By combining AI-driven insights with human expertise, teams can optimize performance, improve compliance, and drive meaningful improvements at scale.
The Most Effective Contact Centers Combine Auto QA and Manual QA
The best call center quality assurance programs don’t choose between manual QA and Auto QA—they use both. Auto QA provides broad coverage, evaluating 100% of interactions to surface patterns, compliance risks, and coaching opportunities at scale. Manual QA brings human expertise, uncovering context, intent, and root causes that automation alone can’t fully capture.
Why Leading Teams Use a Hybrid QA Approach
- 🔹 Auto QA for high-volume analysis: AI scans every interaction to identify trends, flag risks, and pinpoint coaching opportunities across all conversations.
- 🔹 Manual QA for deep-dive reviews: QA teams investigate complex cases, policy adherence, and soft skills that require human judgment.
- 🔹 More targeted coaching: Instead of randomly reviewing interactions, managers focus manual evaluations where they matter most, improving feedback and performance.
- 🔹 Stronger compliance monitoring: Auto QA detects risks in real time, while manual QA ensures critical nuances—like regulatory interpretations—are reviewed with precision.
This hybrid model eliminates guesswork. Instead of hoping manual sampling catches key issues, Auto QA pinpoints where human expertise is needed.
The result? More accurate evaluations, better coaching, and stronger compliance.

How Auto QA Helps Teams Focus Their Deep Dives
A great example of Auto QA and manual QA working together is Upwork’s chatbot quality assurance strategy. Their chatbot was designed to handle customer inquiries at scale, but AI hallucinations, inconsistent responses, and limited visibility made it difficult to ensure accuracy.
At first, Upwork relied on manual QA, reviewing just 1% of chatbot interactions in spreadsheets. This process took 16+ hours per week, yet still left critical blind spots in chatbot performance. Without broader visibility, improvements were reactive instead of proactive.
By integrating Auto QA for large-scale analysis, Upwork could pinpoint exactly where deeper manual reviews were needed. This allowed them to:
- ✅ Cut review time from 16 hours per week to seconds: Automation eliminated the need for random sampling and inefficient audits.
- ✅ Improve chatbot accuracy: Auto QA surfaced patterns and common failure points, making refinements more targeted.
- ✅ Enhance escalation tracking: The team pinpointed where and why chatbot interactions failed, refining escalation logic.
- ✅ Shift from reactive to proactive improvements: With full visibility into chatbot interactions, Upwork optimizes responses before issues escalate.
The takeaway? Auto QA doesn’t replace manual QA—it makes it more effective. Instead of searching blindly, teams know where to focus their efforts, leading to smarter optimizations and a stronger customer experience.
