Sittin Next To Nelly
Its a training technique in which technical skills and professional skills are not acquired in the classroom but through observation of and gradual participation in practice. It is often reffer to as "learning from experienced workers".
It gained its name because she (Nelly) was the lady who knew the most about it, and who taught you everything that you needed to know. During the 1950 was a popular way to learn a machine skill but collapsed during the 70's and 80's.
