@inproceedings { , title = {Persona cases: a technique for grounding personas.}, abstract = {Personas are a popular technique in User-Centered Design, however their validity can be called into question. While the techniques used to developed personas and their integration with other design activities provide some measure of validity, a persona's legitimacy can be threatened by challenging its characteristics. This note presents Persona Cases: personas whose characteristics are both grounded in, and traceable to their originating source of empirical data. This approach builds on the premise that sense-making in qualitative data analysis is an argumentative activity, and aligns concepts associated with a Grounded Theory analysis with recent work on arguing the characteristics of personas. We illustrate this approach using a case study in the Critical Infrastructure Protection domain.}, conference = {29th Annual CHI conference on human factors in computing systems (CHI 2011)}, doi = {10.1145/1978942.1979274}, isbn = {9781450302289}, note = {INFO COMPLETE (notified by contact 08.12.2021 GB) PERMISSION GRANTED (version = AAM ; embargo = none ; licence = BY-NC ; https://www.acm.org/publications/openaccess\#green 08.12.2021 GB) DOCUMENT READY (downloaded AAM from ResearchGate 08.12.2021 GB) ADDITIONAL INFO: Shamal Faily}, pages = {2267-2270}, publicationstatus = {Published}, publisher = {Association for Computing Machinery (ACM)}, url = {https://rgu-repository.worktribe.com/output/1446700}, keyword = {User personas, User-centred design, Software engineering, Systems security}, year = {2011}, author = {Faily, Shamal and Fléchais, Ivan} }
