I learned a long time ago to set realistic expectations with my clients at not only the beginning of a project but also at the beginning our our first meeting.
People simply want to be heard, appreciated and informed.
For example, if we add a home automation system or a distributed audio system at a client’s home, we let them know what is going to happen throughout the process. Additionally, we design systems that are scalable and can expand. If they want to add another room of automation or audio I let them know at the completion of the first phase that they can call me anytime that they need additional work and that it will continue working seamlessly for them.
