To achieve a more precise understanding of the users’ needs about the INCISIVE system is key in the process of designing the project.

Several INCISIVE UX design workshops were conducted in the first year of the project in the framework of Work Package 2 “User Requirements Definition and System Design”. Within this WP, Task 2.2 involves the organisation, facilitation and conducting of User Experience (UX) design workshops, aiming at better understanding of INCISIVE user needs and experiences, mainly in terms of features required in INCISIVE design and implementation barriers. Kingston University (KU) has been responsible for the coordination of the execution and completion of this task.

In order to achieve a more comprehensive and precise understanding of the users’ needs about the INCISIVE system, the project partners also prioritised the INCISIVE features and implementation barriers through conducting a Delphi study. Delphi is a form of iterative enquiry that builds on ongoing data collection. Its primary research tool is a series of questionnaires built from participants’ stepwise input (i.e.: a series of sequential questionnaires).

Taking into account the main expected results by the INCISIVE project, namely an AI toolbox/platform and a repository of health data including medical images, two categories of users were targeted for the UX design workshops and the Delphi study:

• (1) HCPs (healthcare professionals) involved in cancer care who are anticipated to be the primary users of the proposed AI toolbox and
• (2) AI experts and researchers who are anticipated to be the primary users of the proposed INCISIVE repository.

In total, six workshops were conducted online between August and September 2021. Four workshops were dedicated to the AI toolbox, one workshop for each cancer type analysed in INCISIVE (breast, lung, colorectal and prostate cancer). Two workshops were conducted with potential users of the INCISIVE repository. Additionally, two Delphi studies were conducted, one with potential users of the INCISIVE AI toolbox and the other with potential users of the INCISIVE repository.

Each workshop lasted an average of 60-90 minutes. During the workshops the methodological tools of design thinking were utilised. Design thinking is a design methodology that provides a solution-based approach to solving problems. It is a five-stage process used to understand users, challenge assumptions, redefine problems and create innovative solutions to prototype and test. Different use case scenarios were prepared to facilitate discussion for each workshop with users of the AI toolbox (i.e.: HCPs) and with users of the repository (i.e.: AI developers and researchers).

With respect to the INCISIVE AI toolbox, the workshops allowed for the identification of many aspects that are deemed necessary for guiding the design of the INCISIVE AI toolbox mostly in terms of features, data input and output requirements, level of explainability required from the toolbox, and potential user groups. An interesting finding from the workshops is

The results of both UX design workshops, along with user interviews and gap analysis concerning current practice and pathways, informed D2.2 “INCISIVE User Requirements – Final Version” and contributed to the achievement of milestone 2 “INCISIVE initial system design”.
