Are you an expert in IT? I would guess not, since that is not your business, and you probably do not want to be one. However, as IT is now an integral part of almost any type of business, you need your IT infrastructure to work. Any IT failures can lead to a loss of productivity and unnecessary frustration.
What does that have to do with trust? A lot… If you are very reliant on your IT infrastructure and you are not an IT expert, you need someone who is technically competent and who you can trust. If you don’t trust them, you cannot be confident in their recommendations.
So, how do you build trust? A referral is a great place to start. Then, to maintain and deepen the trust, you need someone who can communicate clearly and in terms you (a non-technical person) can understand.
