Has there been a time when a project missed a deadline, there was an error in the source code, or the project did not go as it was supposed to? Whatever the case; this would have resulted in an unhappy client. Unhappy clients mean lost business and happy clients mean long-term business opportunities and new referrals. The client is happy when their perception of your service has exceeded their expectations. The client not only notices your technical performance but also your service performance, which is how you deliver results. Your professionalism, listening skills, availability, responsiveness, and reliability are all factored into the client’s level of satisfaction. These relationship skills can make the difference between a disappointing customer experience and a memorable one, and prove to be your competitive advantage.
