For the information system designer, as an organization designer, the diversity of individuals is a prerequisite.
Indeed, s/he encounters the confrontation of different skewness of individuals.
The designer should respect this diversity, thinking that each skewness has a reason.
System design is of diverse-user-experience-based.
The design of information system satisfying this prerequistes depends on case (usage, aim/goal, user, contents, etc.). But still the point is to realize, at design and implementation, the 'autonomy' of users, in such form as members' self-service.
It includes enabling individuals to take control of their work-related information, which a sort of self-service web applications would put into .
'Diversity' is not necessarily about personal traits. It includes diversity of situations where eache individual is placed, or conditions which each individual is inclined to choose. In this case, the subjects of 'self-service systems' is such as flexibility enough to encompass a wide variety of access channels and delivery modes (e.g., types of PC, OS, Web-browser).
And, the skewness of designer her/him-self is also the prime key issue s/he should reflect. The designer has her/his own perceptions of how 'good' or 'bad' a system is, which is skewed by her/his personal backgrounds and specialties within given fields.
