You work for a company that specializes in digitalizing veterinarian offices. Your first user interview is with the receptionist. He/she describes the following:

“The client telephones in for an appointment. I first check the appointment book for the next available appointment and provide the client with a date and time. If the client agrees to the date and time, I enter the client’s name, and the pets name into the time block. If the time is unsuitable, I continue to read out times and dates until the client agrees with the time. I then enter that date and time into the appointment book. We really need a web-based tool to allow the client to book their own appointments”.
