Dear Francois,
Organogenesis is a term often used very loosely.  It being the formation 
of organs during embryogenesis, I would say, the beginning would be at 
the first sign of the first organ, the nervous system.  This would be 
around the end of gastrulation, (90%epiboly or so), when the neural 
plate becomes apparent. The nervous system is also considered to be the 
last organ to finish development, and some would even say that it 
continues to develop throughout life.

My two cents.
