Abstract:
This study presents a design thinking technique that facilitates the discovery and exploitation of tacit processes in advanced system users. The design thinking technique targets tacit processes that have accumulated over prolonged periods of technology use, in the absence of conscious reflection. Such tacit processes may be impossible for users to verbalize, as the manner in which they have been learned means that users may be unaware that they exist. This makes them difficult or even impossible to uncover with traditional discursive and participatory approaches. For this reason, the proposed technique offers a means of ‘lesioning’ information sources, i.e. removing aspects of the information system and observing how and when behavior breaks down. This deconstruction allows dependencies to be exposed, resulting in a better understanding of tacit processes, and consequently, improved assimilation of them into design ideation. This technique is tested over multiple experimental iterations in the context of Twitter, a social network and micro-blogging service. These iterations present several insights regarding how users determine which users to follow, as well as how information is consumed on a user’s content feed.
