Recommendation : 7. Limit the use of hardware components or sensors on user terminals
Do you inform users of the size constraints and accepted file format ?
Are file sizes and formats limited and exposed to users?
Front-end operations may require file transfers between the user workstation and the processing servers. The types and volumes of files accepted must be exposed to the user to avoid transfer loads, storage and processing that would be doomed to failure due to non-compliance with expected formats and volumes. Limiting the volume is essential to reduce the impact of transfers.

Formalized = 100 ; Planned = 75 ; Identified = 50 ; Ignored = 0 / 100
8 other criteria related to the recommendation: Limit the use of hardware components or sensors on user terminals
Are the sensors being used as needed, rather than constantly ?
Are the pause functions available ?
Is the inaccessibility of a sensor, linked to the equipment or to the user's choice, treated to allow the service to be functional nonetheless (if possible) ?
Are predictive algorithms in place to avoid the use of physical sensors ?
Technical User Experience
Is the frequency of the animation appropriate for the functionality ?
Do uploads only allow the list of authorized file types ?
Are the images to be uploaded properly resized and converted to a thin client-side format before transfer ?
Are the exchanged files compressed ?
