Hi, I'm
Ossama Yakhafallah
Operational Excellence Engineer — Lean Six Sigma & Digital Transformation
Dual background in industrial and software engineering. I improve industrial performance through Lean, data, and project management. Currently at Diehl Aerospace, Toulouse.
About Me
About Me
A dual-skilled engineer. First in industrial engineering, where I master the entire value chain, from supplier to customer. Then in software engineering, my specialization, which lets me understand and steer the information systems that keep industry running.
I lead continuous improvement and digital transformation programs: from on-the-ground diagnosis to the rollout of lasting standards, drawing on Lean Six Sigma, data, and project management.
My approach: connecting the shop floor and the data. Understanding a physical flow, measuring it, then optimizing it with the right tools — methodological (Lean, DMAIC) or digital (SAP, BI, Python).
