The present thesis describes the application of Lean Techniques to Site Non Conformities Management Process of GE Oil and Gas Nuovo Pignone Firenze.
Through a problem solving approach, Site Operation Support-the GE Oil and Gas Organization where my internship took place-starts a Lean Project in order to reduce process cycle time.
This work focuses in particular on the most critical portion of the entire process:
the analysis of the defect causes that have generated the Non Conformity and following assignment of the cost of quality to the function responsible for the defect.
Process flow Mapping, sample meausurements and presentation of real cases contribute to give a clear overview of AS IS process.
Going ahead in the core of the project, an overview of all improvements action collected is then given.
Finally a test phase of improvement action is carried on. The result is a description of TO BE process status.
