1. Training is an activitiy that is imparted to someone to perform a specific task. It can be for anyone. In circus, the animals are trained to do cycling, jumping, sitting with two legs, etc. I saw a news article recently in The Hindu, that in a zoo, a chimp has been trained to (bottle) feed tiger cubs with a photo. This is what training. it gets completed once the task is over. Then you move on to different task.
2. But development is something different. It is growth aspect of an individual. You hire a person for your shop floor, teach him the necessary skills to perform the task, do career planning, successiong planning, mould him to match with the requirements of organizaion, so as take high responsibilities. This is what Development. Development can be anything. Developing in career, Developing a child to become a musician, sportsperson, dancer, etc to what you (he/she) want to achieve.
However, without proper training development cannot take place.
