years of Lean & Agile experience



We are the leaders of Lean management in the services and IT industries.

Operae Partners was created in 2007 by Marie-Pia Ignace and Michael Ballé to develop and deploy Lean in these two sectors. Marie-Pia and Michael are two of the major players responsible for bringing correct Lean management practices to France. Together, they co-founded Institut Lean France, a member of the Lean Global Network.
