Challenges of Using Manual Quality Assurance Instead of AI

Traditional manual approaches to quality assurance in customer service face several limitations. These limitations can hinder a business’s understanding of its customer experience, leading to suboptimal support quality.

Manual quality assurance processes are often less efficient and more time-consuming. Human reviewers can typically cover only a small percentage of customer interactions, making it difficult to identify broader trends or recurring issues. This limited coverage means that many potential problems go unnoticed, affecting the overall customer experience.

Human errors and biases are also significant challenges in manual quality assurance. Evaluations by QA teams can be inconsistent due to personal communication preferences, fatigue, or subjective interpretations. This inconsistency can lead to variations in scoring and an unreliable assessment of customer service quality.

Operational and tech stack costs are higher with traditional quality assurance methods. Significant investments in human resources, training, and retaining qualified reviewers are required. Additionally, managing a team of manual reviewers often necessitates additional software or hardware, increasing operational complexity and costs.

Manual quality assurance struggles with scalability. As a business grows, the volume of customer interactions increases, making it difficult for manual quality assurance to keep pace. This requires either hiring more reviewers or compromising the quality of analysis, both of which are not ideal solutions.
