This paper discusses Five Management Pillars for Digital Transformation integrating the Lean Thinking Philosophy. It proposes a "Digital Lean Transformation Framework" where its five management pillars - (Digital) Strategic Management, Processes (Re-)Engineering Management, (Digital) Technology Management, Change (People) Management, and (Digital) Risk Management - are enriched with lean practices and tools in order to support a digital transformation journey. A case study is also presented as a validation mechanism for the proposed framework, demonstrating its capability to enable process-culture-technology alignment, which is a key enabler for success in any digitalization initiative.
