The document outlines the importance of digital-driven integration for leveraging legacy systems in digital transformation, focusing on API management to improve customer interaction and business agility. It discusses challenges, solutions, and benefits associated with integrating legacy assets rapidly, enhancing operational efficiency while reducing costs and time. Examples illustrate how organizations can significantly improve their digital services and meet current market demands by effectively utilizing their existing infrastructure.

Drivers For Digital Transformation

Getting Started – Two Approaches

If you build it, they will come
• Identify a baseline of APIs covering major domains
• Design APIs based on APIX and best practices
• Deploy APIs to the broadest platform possible (on-prem <
Private Cloud < Public Cloud)
• Target developers
• Invest in portals, communication and marketing
Pros: Scalable from start, consumer led, signals importance
Cons: Adoption, ROI, Relevance
First and Best
• Identify an internal customer
• Design APIs based on their needs
• Deploy APIs to the platform best fitting use case
• Iterate based on feedback
• Open to broader audience once mature
• Use success to promote
Pros: Adoption, agile, success brings attention
Cons: Scalability, limited scope, concentration risk

Identifying API Opportunities
4
Internal Developers
• What data and transactions would your
own mobile apps need?
• Does generic data exist that is the same
for all app users, such as business
locations, rates and so on?
• Is there data specific to existing
customers that should be accessible
through your app, such as account
balance or open account status?
Partners
• What data and transactions do you share
among your current partners?
• Is partner onboarding a long, difficult
process?
• Would self-registration of partners be of
value.
increasing the number of partners and
broadening geographic coverage, for
example?
Public
• What apps might others write that could
use your data and transactions?
• What information are you currently making
available on your website?
• What other industries or processes might
also use your products? One example
might be a car purchase that needs a bank
loan.
• Think mashups: What other APIs might
make sense with yours? Mapping? Social?
Social
• How do your systems interact with social
media? Can you spot trends in social
media and raise alerts or act?
• Can you gain insight on your brand and
your competition through social media?
• Can you do real-time analytics combining
current customer status, behavior and
history with social interactions?
Devices
• What features of the device might be
useful in conjunction with your APIs?
(GPS, camera)
• What scenarios can apply to the device?
For example, needing repair/supplies,
needing to send status information,
controlling device behavior or enabling
interaction between the device and
enterprise systems.
• How are you positioned to integrate the
next UI technology, such as wearables
like smart clothing or augmented reality
glasses?
Data
• What data do you collect about your
clients? Would this data be of value to a
larger audience inside the enterprise?
• Can your data identify market segments
that would be of interest to a non-related
industry? For example, can it identify a
high volume of expensive credit card
purchases in a region of the city? Or can
it identify a high percentage of wealth
management investments being moved to
low-risk funds for retirement planning in
certain times of the year?

API as a Product

INTEGRATIONS
Supply-side thinking
• Asset oriented
• Project
• Tightly coupled integrations
• Finite scalability (sized for the known)
• Monolithic middleware
• Horizontal teams
• Measured for quality
API PRODUCTS
Demand-side thinking
• Consumer-oriented
• Continuously managed product
• Self-service consumable
• Elastic/infinite resource
• Microservices
• Cross-functional teams
• Measured for value

What problem does digital-driven integration solve?
Legacy systems hold 80%
of the world’s data, and are
in 71% of Fortune 500
companies
Companies know how to
create legacy system APIs,
but it takes months. Digital-
driven integration reduces
risk, cost, time, & resources
Closed legacy systems
are not ‘digital-friendly.’
Over 80% of all digital
transformation projects
are either seriously
delayed or fail due to
integration challenges
The Situation The Challenge The Solution

Why is it important?
7
For the Business:
• Cost savings of MM yearly for large
enterprises
• Do more with less, OR do more with same
• Faster time-to-market, time-to-revenue
• React and respond quickly to market
pressures
• Fiercely defend market share from nimble
start-ups
For the IT Team:
• Increase capacity to deliver with same team
• APIs from legacy systems in days versus
months
• Leverage legacy assets faster, internally &
externally
• Simplify IT stack, lower Total Cost of
Ownership (TCO)
• Commoditize skill sets, Java developers can
do more

Result is that digital
services pass thru these
complex layers which
impacts API performance.
Layers of ESB/SOA add
complexity, requiring more
people and specific
skillsets.
Legacy systems of all
types require special skills
and a dwindling
workforce.
