This paper analyzes the transformation of XYZ's engineering business unit during the company's transition from start-up to SME. Faced with technical debt, delivery delays, and organizational stress, XYZ launched a major restructuring to increase throughput at its operational bottleneck—the engineering department. The new CTO implemented a task-aligned strategy emphasizing process redesign, modern engineering practices, and expert coaching. Using Lewin's Force Field Analysis and Bridges' Transition Model, the study assesses how the organization managed both the structural change and the human transition. Findings show that XYZ's success stemmed from removing restraining forces—such as complexity, mistrust, and skill gaps—rather than intensifying pressure for change. Although the early phase of "letting go" was insufficiently supported, strong leadership, communication, and quick wins helped guide teams through the neutral zone to full adoption. The transformation stabilized operations, improved collaboration, and laid the foundation for sustained organizational learning.
