You should have training available to all your employees. This will give you the largest available pool of employees to choose from for advancement.
Question: Why would I want to include operators and part inspectors in my training plan?
My Response: You never know where your next technician could come from. Technical proficiency is something you can develop over time. When you expose your employees to more information, some will be indifferent, while others will want to learn more and expand their knowledge. Unfortunately, many of the people who want to learn more do not even realize it until the information is made available. Our customers are often surprised at whom wants to learn and improve.
