Goals should be broadly defined,
measurable, and user-centered
1. To give API consumers a way to discover
and securely access available APIs across
their organizations.
2. To give service providers a way to
manage access to their APIs.

Assumption Generation
Empathize
Assumptions are things that we believe
to be true BUT which are not based on
facts or evidence.
1. Consumers want to access API
documentation for endpoints
2. Consumers have trouble securely
accessing APIs
3. Consumers want to try out (test) an
API before using

Research Synthesis
The goal of
synthesis is to
make sense of
your research
data. Identify
patterns that
improve your
understanding
about users and
summarize your
finding into clear
insights and
problems.

37. 37
API Managers want key
observability
"Information would be absolutely useful"
"Observability would help identify bad
customers”
“Audit trail would be helpful because it
would tell us who accessed what when.”
