1. Teach Skills Not Traits
Don’t pay attention to change types of individual personality, let coach and tutor skills that can be taught and learned.
For instance, you work as a field engineer to be responsible for going on customer calls. If he is a reserved person (a trait), don’t attempt to force him to be more extroverted to help you sell.As an alternative, train him how to listen actively (a skill) and how to use terminology customers will understand (a skill)

2. Teach the Appropriate Skill
Need to forcus on teaching skills you ensure that it generates obvious results in range of job’s content.
For example, if a group of salesman consists of hunters (who find new business) and farmers (who develop existing accounts), it's wasteful to train everybody on the team on cold-calling techniques. Limit such training to the hunters and provide training in other skills (like account management) to the farmers.

3. Enhance and Support the Skill
Provide several chances to test on how workers are carrying out those skill and give guidelines as necessary.
Studying a new skill entails turning it into a custom.Unfortunately, doing so usually involves overcoming existing habits, which is inherently difficult. Coaching allows you gradually reinforce the ability and overcome the habits it replaces.

4. Carry out skill-based metrics
Maybe you heard “what gets measured gets done” in business. So if you really want your staffs to make a skill into their daily practice, you have to measure the results of the application of those skills
For example, if you're supplying training on some respects of your sales process, you should evaluate the conversion rate at that stage of the sales process, rather than just measuring the total revenue that's noted at the end of the quarter.

5. Consistently Measure Progress – systematically measure progress
When you complete all of the above, you have responsibility to check the data improve as the new ability becomes second nature. If you don’t have the desirable improvement, there’s something wrong. Either you've been teaching the incorrect skill or not supplying enough supplement and training.
