Developing scalable quality assurance pipelines for AI systems: Leveraging LLMs in enterprise applications

Pandhare, Harshad Vijay (2025) Developing scalable quality assurance pipelines for AI systems: Leveraging LLMs in enterprise applications. World Journal of Advanced Research and Reviews, 26 (1). pp. 1871-1894. ISSN 2581-9615

With Enterprises rapidly including Large Language Models (LLMs) in their core operations, from customer service to finance to healthcare to e-commerce, there is an urgent need to pay utmost attention to the scalability and robustness of quality assurance (QA) pipelines. LLMs are probabilistic, sensitive to the context, and non-deterministic, so traditional QA methods fail them. In this article, we look at what organizations can do to build scalable QA frameworks to address the peculiar requirements and possibilities of AI systems built on LLMs. We first look at what sets LLM-specific QA apart from conventional software QA, ranging from output unpredictability to hallucination hazards and the need to ensure bias and fairness. After that, the article specifies the core components of a modern QA pipeline: automation, reproducibility, observability, and continuous integration to share best practices for each. The paper goes in-depth into the technical architecture, data quality validation, synthetic testing strategies, and how human-in-the-loop processes can be used to provide nuanced evaluation. Leading enterprises in JPMorgan Chase, Amazon, and the healthcare industry have demonstrated real-world case studies of how they moved fast and deployed rigorous QA frameworks to gain reliability from these LLMs and compliance and trust from their users. Tools and technology for QA are discussed, ranging from open-source testing frameworks MLOps stacks, and NLP validation platforms. Finally, we examine future relationships between self-healing AI systems, autonomous QA agents, and multimodal validation pipelines in the context of adaptive intelligent QA strategies that define the enterprise AI of the future. The article discusses ideas for building responsible, scalable, enterprise-ready AI systems.
