Agile project management has been widely applied, especially in software development projects, but there are still very few implementations in IT Infrastructure projects. This study aims to improve knowledge about the implementation of agile project management on IT Infrastructure. This paper uses case studies and Design Science Research Methodology on a pharmaceutical company that transforms the IT network infrastructure for branch offices from conventional WAN topology to SD-WAN topology, managed by agile project management Lean and Kanban. As a contribution, this study proposes a project management model for IT Infrastructure agile adoption inspired by Kanban and Lean agile project management frameworks for implementing network transformation. © 2021 IEEE.
