From Wikipedia: Web Design is a PROCESS of conceptualization, planning, modeling, and execution of electronic media content delivery via Internet in the form of technologies (such as markup languages) suitable for interpretation and display by a web browser or other web-based graphical user interfaces (GUIs).
The key to a successful website project is the PROCESS that is followed. Here at ISG, we've spent years developing and fine tuning our process. Your project will be orchestrated by a project manager. The project manager works with the customer to define the goals, requirements, and budget for the website. The project manager then communicates and coordinates with the graphic artists and programmers to turn ideas into reality. Our process is iterative and is centered around the customer.
