Your ability to communicate effectively with the unique personalities of your customers affects your project’s success. There are several personality typing systems to explore. Check out the CAP Model at Speechmastery to learn about the 4 types: The Controller, The Analyst, The Supporter and The Promoter. Identifying your client’s personality type will help you better understand what motivates their interest. For instance, engineers are typically ‘analyst types’ who will ask infinite questions. They love gathering information before acting. So with an analyst type you want to be as prepared as possible to provide answers, or know where to find them. For instance, if you are designing or building an energy efficient home, you want to be well-versed on the latest information and ready for their questions.
