Managing the Full Lifecycle of LLM-Based Software Products

As organizations increasingly adopt Large Language Models (LLMs) in production environments, managing their full lifecycle becomes critical to ensuring reliability, scalability, and long-term value. Unlike traditional software, LLM-based systems require continuous iteration, data management, evaluation, and governance. A structured lifecycle approach helps teams move from experimentation to stable, high-performing AI products.

Step 1: Defining Product Scope and Use Cases 🧭
