Renault's financial problems were not all fixed by the privatisation, and Renault's President, Louis Schweitzer gave to his then deputy, Carlos Ghosn, the task of confronting them. Ghosn elaborated a plan to cut costs for the period 1998–2000, reducing the workforce, revising production processes, standardising vehicle parts and pushing the launch of new models. The company also undertook organisational changes, introducing a lean production system with delegate responsibilities inspired by Japanese systems (the "Renault Production Way"), reforming work methods and centralising research and development at its Technocentre to reduce vehicle conception costs while accelerating such conception.
