Agile
FSI services should offer an
exceptional end-to-end
personalized seamless
customer journey to clients,
leveraging technology to
create this experience.
FSI organizations have tons
of data about customers.
Using big data, cloud, and
AI to generate insights and
knowledge from this data will
allow companies to improve,
innovate, be proactive, and
develop new business
models.
All communications must
maintain and deliver the
same experience to clients,
keeping the customer
satisfied and connected.
Delivering early, and
continuous, value to
customers, accepting
change, and failure, are just
some of the Agile values
that builds a customer
centric culture.
24/7/365. A bank that
doesn't sleep and it's able to
provide a stable, and
reliable, experience any
time.

6. Innovation
Open APIs
What changes?
More companies, more offers… Open Banking will
force companies to be more competitive if they
want to stand out for clients
Competitivity
New platforms to contact clients
Channels
To support these new operations, and the data
created/analyzed, banks will need to innovate while
adopting new technologies
Fast and cheap
The process it's cheaper and faster because it has
less participants
New Partners
Other companies can offer banks services using the
banks partner APIs. These APIs can be monetized
and these connections can give banks the freedom
to work at their core systems.

CLOUD-NATIVE

Cloud-native Definition
Cloud native technologies empower organizations to build and run scalable applications in modern, dynamic
environments such as public, private, and hybrid clouds. Containers, service meshes, microservices, immutable
infrastructure, and declarative APIs exemplify this approach.
These techniques enable loosely coupled systems that are resilient, manageable, and observable. Combined with
robust automation, they allow engineers to make high-impact changes frequently and predictably with minimal toil.
