Stratexis

Stratexis' intervention, at the crossing of communication, human resources  and information technology, is targeted to facilitate the integration  of the user point of view before, during or after the development of the site. We help our clients to put in practice the principles of Human Centered Conception and determine precisely the way their users will interact with the interface, in order to :

• Understand users’ intentions and connect them with the elements of the user interface.
• Test their behavior early and frequently, using ‘rapid’ prototyping techniques.
• Use the knowledge gathered through design iterations to make the interface evolve in the desired direction.
• Insure an on going optimization of system’s interactivity.

Evaluation & Audit
attention is focused on actual problems and future potential

The audit of an existing interface allows the understanding of a client specific problem set. Thus opening directions to recommendations about the next steps. Experience shows that early evaluation helps to avoid expensive errors. Topics : Informal Inspection ; Heuristic Evaluation ; Expert Evaluation ; User Experience Audit ; Guideline Reviews,  etc.

Context Analysis
attention is focused on the context of use

The research of qualitative and factual data allows to enlighten the project initial requirements . No project can succeed without a previous research. Topics : Business Purpose ; Product Description and Specification ; Circumstances of Use Analysis ; User Requirements Gathering and Specification ; Data Analysis and Consolidation of the Findings, etc.

Interface Design
attention is focused on the users

Rapid prototyping and frequent iterations (prototype, test, re-design, etc.) ease the progressive integration of the user into the design and keep the creative process fluid. Visual layers have to accommodate user’s mental model, i.e. being displayed following the movement and in the order he is expecting them. Topics : Information Architecture ; Paper and Low-Fi Prototyping ; Formative Evaluation; Fast Iterations ; Concurrent Development ; Internationalization - Localization, etc.

Usability Review
attention is focused on product’s improvement

Usability is a dimension which manifests itself only when a product is in use. It is the key underlying the success of any interactive product. It finally guarantees an attractive, intuitive, and ease to use product. Topics:

• Performance : measure test of effectiveness and efficiency in use, e.g. task completion rate, time on task, relative user efficiency, 'eye tracking' (through a partnership with the Experimental and Quantitative Psychology Laboratory at the University of Nice), etc.
• Preferences : exploratory test of information space partitioning and search strategies e.g. visual grid, task design, hyperlinks' rhetoric, text comprehension through 'thinking out loud' and 'co-discovery' protocols, etc.
• Satisfaction : psychometric test for the measurement of user's subjective satisfaction, cognitive load assessment, critical incidents analysis, etc.
