Separating Business Logic from LLMs for Reliable Enterprise AI

The article discusses a blog post titled "Beyond Prompt-and-Pray" by Hugo Bowne-Anderson and Alan Nichol. The authors argue against the "prompt and pray" approach to AI implementation.

Key Points

The piece highlights that relying solely on LLMs to manage workflows becomes problematic beyond prototyping. The authors note that "Complex workflows require more control than simply trusting an LLM to figure everything out… Debugging these systems is a nightmare…"

They propose "structured automation" as an alternative—a development methodology that separates conversational AI's natural language understanding from deterministic workflow execution.

Main Argument

Rather than giving AI systems complete autonomy, the authors advocate for intelligent deployment of their capabilities. As they state: "The future of enterprise conversational AI isn't in giving models more runtime autonomy—it's in using their capabilities more intelligently to create reliable, maintainable systems."

Liana Leahy, the blog's author, agrees that maintaining focused, thoughtful user experiences requires predefined, testable workflows that isolate business logic from conversational features. This separation ensures reliability, security, and safety in enterprise applications while maintaining human oversight.

The post concludes that this approach—combining natural language understanding with clear workflows—remains essential for dependable AI systems.
