I believe in triangle concept came from a prespective that there is an invisible mutualism relationship among graphic designer, client, and the society. Client plays the role as producer for goods and services, who need the help of graphic designer to make their products more attractive and commercial for the society as the buyer. Graphic designers need clients for business purposes and to sharpen their skills, but they also need the society to see wether their design has been precisely accepted and has the ability to be a strong advertising or brand imaging that make the society buy the products or use the services offered by clients as the producer Meanwhile, for the society, they need goods and services to meet their needs. Regarding this mutualism relationship, i have value to respect each other so each of us can get the best from each other.
