CAPTURE: A Stakeholder-Centered Iterative MLOps Lifecycle

RWTH Publications (RWTH Aachen)

Abstract

Current ML lifecycle frameworks provide limited support for continuous stakeholder alignment and infrastructure evolution, particularly in sensor-based AI systems.We present CAPTURE, a seven-phase framework (Consult, Articulate, Protocol, Terraform, Utilize, Reify, Evolve) that integrates stakeholder-centered requirements engineering with MLOps practices to address these gaps.The framework was synthesized from four established standards (ISO/IEC 22989, ISO 9241-210, CRISP-ML(Q), SE4ML) and validated through a longitudinal five-year case study of a psychomotor skill learning system alongside semi-structured interviews with ten domain experts.The evaluation demonstrates that CAPTURE supports governance of iterative development and strategic evolution through explicit decision gates.Expert assessments confirm the necessity of the intermediate stakeholder-alignment layer and substantiate the participatory modeling approach.By connecting technical MLOps with human-centered design, CAPTURE reduces the risk that sensor-based AI systems become ungoverned, non-compliant, or misaligned with user needs over time.
