7. UX and technical architecture changes made
Axes of optimization
INTERFACE / UX
Maximum value for
minimum resources :
Suppress step when already
known information
Respond to essential
need rather than a
maximum of need :
Minimize the number of
centers/slots displayed
Maximize terminal’s
lifetime :
Extension of devices
compatibility
CODING POLICY
Data gradually loaded
Cache management
Reduce the weight of images
ARCHITECTURE
Angular frontend and backend
for sending data at the end
Cloud-ready &
elastic architecture

Path to the industrialization of Sustainable IT15
Findings :
Key for future investment
Key for prioritization
Based on assumption that need to be apply until the end
Challenges :
Calculation method of some optimization axes
valorization
Lack of return on experience

16. Conclusion
We are only at the start of one of the biggest challenges of
the next decade for our industry
This will require strong coopetition
Fortunately, the ecosystem is answering the call
Little steps can already be done without strong investment
Regulation is coming and will require return on experience
As an ESN, we have the opportunity to act as a catalyst with our client
to accelerate this transition.
