AB - Generative AI services require lifecycle support for Prompt Engineering, Retrieval-Augmented Generation (RAG), user experience (UX), and continuous improvement, which existing frameworks such as CRISP-DM, OSEMN, MLOps, and CRISP-ML(Q) do not fully address. This paper compares these frameworks using lifecycle-based criteria and proposes an integrated framework that incorporates business understanding, UX, data and RAG design, Prompt Engineering, generative AI modeling, service design, LLMOps-based operation, monitoring and feedback, and continuous improvement. Comparative analysis and exploratory expert evaluation indicate the conceptual applicability and structural adequacy of the proposed framework for supporting the Generative AI service lifecycle. The results are exploratory and do not constitute empirical evidence of performance improvement.
