Now, that certainly tells us just how much thought about context goes into successfuldesigning.Delving a bit deeper into context we find there are several kinds of users about allof whom we need to know.There are at least three types of users; the primary user, the secondary user, and thetertiary user.In case of the office chair, the primary user is the person who is going to sit in the chair.The secondary user could be the people buying and maintaining the chair, and the tertiaryusers are the ones who are manufacturing and transporting.The designer must understand the requirements of each user, so that all the user issuesare taken care of.So, now, we have multiple contexts to look at.So, that was about understanding multiple users, but when it comes to personal issueslike health and diet.We need to understand the socio-cultural context of the users, go to the tab and you know whatto do.
