■ API adoption by both internal and
external consumers is critical
■ APIs need to be easy to find:
catalogue in developer portal
■ APIs need to be easy to access:
ensure self-serve access
■ APIs need to be easy to use:
documentation must exist before
delivery is signed off
Understand the consumption lifecycle
■ Capture and optimise the user journey
for each persona and type of
consumer
■ Consider a pilot or beta programme
with a subset of internal/external
consumers
■ Identify all stakeholders that need to
sign off delivery and invest in ongoing
adoption
Define and document the adoption path
Adoption: turning APIs into value
