BPO refers to a form of outsourcing in which a company delegates specific business processes to an external specialized vendor. AI Hybrid BPO, which combines BPO with automation leveraging AI, has been attracting significant attention in recent years.
BPO (Business Process Outsourcing) is a form of outsourcing in which a company delegates specific business processes to external specialized vendors. It covers a wide range of areas, from back-office operations such as accounting, human resources, and customer support, to marketing operations, procurement, and logistics management.
Focusing on core competencies is essential for companies to maintain a competitive advantage. However, as organizations grow, ancillary operations expand, placing pressure on human resources, costs, and management workload. BPO has gradually evolved as a structural solution to this challenge, developing in parallel with the broader spread of outsourcing in the manufacturing sector.
In recent years, BPO has come to be positioned not merely as a means of cost reduction, but as a strategic partnership through which companies source specialized expertise, technology, and scalability from external providers.
The most noteworthy trend in the evolution of BPO is its convergence with AI. Traditional BPO centered on manual processing, but with the growing practical adoption of LLMs (Large Language Models) and AI agents, "AI Hybrid BPO" — which combines an automation layer with a human judgment layer — is on the rise.
In practice, this typically involves the following structure:
This structure is closely related to the framework of In the Loop, On the Loop, and Outside the Loop, which describes the degree of human involvement. Determining how much human oversight to incorporate into each process is a core design decision in BPO.
The following are representative areas where BPO is commonly applied:
There are several issues that tend to be overlooked when implementing BPO.
Information security and data governance are among the most critical concerns. Since confidential information is passed to the vendor, it is essential to verify in advance whether encryption such as AES-256 and an AI governance framework are in place. Compliance with regional regulations — such as the PDPA (Personal Data Protection Act, Thailand) and the EU AI Act — is also a point that warrants careful scrutiny.
Vendor lock-in risk is another factor that cannot be ignored. Excessive dependence on a specific vendor can make it difficult to transfer operations when a contract ends. It is important to clearly document the scope of delegation, KPIs, and quality standards, and to establish a mechanism for ongoing evaluation from the perspective of AI ROI (AI Return on Investment).
In addition, the issue of Shadow AI deserves consideration. Cases in which vendor staff use unauthorized AI tools in their work are increasing, potentially leading to information leakage risks and inconsistencies in quality.
BPO is not simply an act of "outsourcing." Its true value is realized when it is approached as an opportunity to holistically reassess one's own operational design, technology strategy, and risk management.



"Outside the Loop" is a collaboration mode in which humans specify only the outcome requirements and delegate all implementation details to AI agents; it is also known as vibe coding.

An autonomous AI agent that takes on a specific business role and continuously performs tasks in the same manner as a human employee. It differs from conventional AI assistants in that it holds a defined scope of responsibility as a job function, rather than simply responding to one-off instructions.

An AI agent is an AI system that autonomously formulates plans toward given goals and executes tasks by invoking external tools.

An algorithm that merges text based on frequent patterns and splits it into subword units. It directly affects the input/output cost and processing speed of LLMs; for low-resource languages, insufficient dedicated vocabulary leads to byte-level decomposition.

An AI chatbot is software that leverages natural language processing (NLP) and LLMs to automatically conduct conversations with humans. Unlike traditional rule-based chatbots, it is characterized by its ability to understand context and respond to questions that have not been predefined.
