7. Organizational Strategy & Alignment
 Often Company goals are articulated at a
very high level and have many disjointed
strategies.
 The need to have an aligned Partner, Digital
and API strategy with Clearly defined
Missions and Goals, in line with the
corporate strategy is essential.
 These Missions & Goals should be:
 Clear & Strategically grounded
 Valuable and measurable
 Holistic in scope

across
 Not up to date or
Not defined at all -
Standards,
Guidelines and
Principles not up to
date or not defined
at all.
 More Provider-
Driven APIs
 Inconsistent API
Documentation
 API Ownership
lacking or non-
existent

API Governance & Design

9. 9
API Governance & Design
Provide Guidelines as early as
possible.
Inbuilt governance into your
automation as much as possible.
APIs should talk business
language & should be
system agnostic.
Always have a hybrid
Design review model in
place
Consistency and Repeatability
is the Key
