Relying on trust in the business world is certainly a good decision.
Three important ingredients for trust are positive relationships, good judgment/knowledge and consistency.
How can these be reinforced?
This is where the concept of follow up, follow through and follow back comes in.
Following up on inquiries, contacts, expressions of interest with open-ended questions and your own interest, not only in the business but also in the positive relationship.
Following up on projects, delivering on a promise.
Follow-back of contacts and customers, even if the project is terminated.
What happens?
Is this how positive relationships are created? Does the partner have a chance to assess knowledge and judgment? Is it consistent and consistent?
I think so.
