This review explores the strategic integration of Lean-Agile change management frameworks and enterprise architecture (EA) alignment in driving successful agile transformations within public sector IT projects. Unlike the private sector, public institutions often operate under rigid regulatory frameworks, legacy systems, and complex stakeholder landscapes, which pose significant barriers to agile adoption. This paper critically examines how Lean-Agile principles—such as incremental delivery, customer-centric value streams, and cross-functional collaboration—can be tailored to the public sector’s unique operational constraints to enhance IT service delivery, transparency, and responsiveness. The study also evaluates the pivotal role of enterprise architecture in aligning business goals with agile practices by providing a structural blueprint that harmonizes governance, digital infrastructure, and evolving stakeholder needs. Key focus areas include the synchronization of EA layers with agile portfolios, the role of leadership in orchestrating agile governance, and the adoption of value stream mapping to eliminate bureaucratic inefficiencies. Through the synthesis of case studies, industry frameworks like SAFe (Scaled Agile Framework) and TOGAF (The Open Group Architecture Framework), and empirical findings, the review highlights best practices, implementation challenges, and metrics for evaluating transformation success. Ultimately, the paper provides a comprehensive roadmap for public organizations aiming to modernize IT delivery through scalable, sustainable agile transformation strategies rooted in enterprise alignment and lean governance principles.
