Dear Rudradeva,
Your query is on a macro level whereas forums like this handle micro-level queries.
Just pull out any book on Human Resource Development and you will find a chapter on employee training. If you don't know anything about employee training, then you need to refer to those books and upgrade your knowledge.
Secondly, just search this forum and you will find that lot of material is available on employee training. A lot of seniors (including me) have given replies to the queries on this subject. You could have referred to those before raising the query.
Earlier I have given exhaustive reply on this subject. Click the following link to refer it:
