You could have given a little more information about yourself. Are you a student or a professional? Are you from the Training or HR Department? Do you handle the delivery of the training? What is the nature of the industry? What kind of pre-training analysis do you conduct about your organization? There are so many questions associated with your post.
Kirkpatrick Model: Level III and IV
It appears that your post is about Level III and Level IV of the Kirkpatrick Model that measures training effectiveness. Following this model is very difficult. If going from Level I and then rising to Level IV were that easy, then a large number of training companies or HODs of Training Departments would have provided their case studies on how and what changes they could bring through employee training. However, these examples are hard to come by.
You can bypass Level II and III of this model and leapfrog to Level IV. How? To know this, you may check my earlier reply to a similar query. Click the following link to refer to it:
