How can Field Service Engineers receive positive feedback?

Something I've always felt was inportant is making sure you listen to the customer first. Try to understand where they are coming from and what level thier thinking is. The last thing you want to do is come off over powering and aggressive to the customer. You dont want to accidently talk down to them or say things over thier head.

Sometimes it is good that an FSE can think on thier own and think outside the box sometimes. BUT the FSE should always keep thier training as thier base practice. Follow the procedures put in place first.

Managers and supervisors should always make sure that the FSEs are comfortable enough to come to them when they need to. The FSE should always feel he can trust his Supervisor or Manager to help and not chastise. The FSE should also make sure he learns and obtains what he learned so he doesn't continue to make the same mistakes or have to ask for help on that particular subject again.

FSE should have high curiosity and eager for information. For example some of the things is shown at controller display, they should have curiosity on how the controller work; where the value and reading comes from,if they know on the derivation then it will be great means that they know and understand well instead just applying or read only the value or reading from display. The one who into deep regarding things is much more better compared to the one who just applying it.

Everyone who's focusing on his job, does it with the highest level of professionalism and honesty, will always get great feedback, and for a field service engineer, a one should does his service based on a deep understanding of the governing principals and a close studying for each case by reversing the case condition, looking at numbers, know the real meaning of each number and what does it needs to be adjusted, searching of each possible cause, deep diving in the root causes of each case, that will result in the most accurate decision. This approache will always gives the right solutions, and this will keep the customers satisfied to give a wonderful feedback.

they way of communicating with customers and management, Good and technical speaking always give you good feedback .another important thing is your skills satisfied customers and management

Going the "extra mile" takes time and experience. Not every FSE is going to have that. So, in reality, when the experience comes, going that extra mile will just be standard practice of knowing what to look for and check, while doing whatever you may be there to do.
