From Lean to Agile and DevOps: A Personal Journey in Project Management

The author begins by describing how an early encounter with Lean management reshaped their mindset, emphasizing the identification of internal and external customers, defining value based on client needs, and recognizing value streams to eliminate waste and drive continuous improvement.

Concrete Lean lessons are illustrated through personal work scenarios—sales, PMO workflow optimization, and documentation practices—showing how value‑centric thinking guides stakeholder communication, process analysis, and consensus building.

Transitioning to Agile, the author reflects on experiences in a bank’s IT department, adopting iterative, incremental delivery, and value‑flow mapping to address complex, multi‑system projects, while highlighting the limitations of traditional project‑management frameworks.

In the DevOps chapter, the narrative covers a shift to an internet company where tools such as Jira, Confluence, Jenkins, Maven, and Git enable rapid releases, followed by challenges in a legacy environment that prompted micro‑service adoption, Docker containerization, and Sonar‑driven technical debt reduction, underscoring the need for end‑to‑end lifecycle awareness.

The piece concludes with a reflective summary of the author’s professional path, an invitation to peers for shared learning, and a brief author bio emphasizing certifications and a passion for project‑management science.
