Secondary design - as a supplementary knowledge base for HCI design

Traditionally, the HCI design is greatly influenced by active knowledge harnessed during requirement elicitations. However, as the world of ICT moves towards user-centric computing with a need for evolving features, designers face challenges from heterogeneous users with complex needs, accessing technology with myriads of communication mediums. In response, this paper explores peoples' inherent desire and way of engagement with other entities which guides us towards design that is not pre-determined by experts, but by users' response to changes (secondary design). Secondary design is analyzed in an empirical case study of the implementation of new Learning Management System in higher education institution by following end-users appropriation response for a period of 20 months, and conducting more than 30 interviews. The analysis shows that secondary design is not `unfaithful use of technology' but a sensible practice with known triggers and effective re-designing processes aiming to fit new features with practices and identities.
